response of several of these systems. They include an active
bracing system and an active mass damper system installed in a
six-story experimental building, and two hybrid mass damper systems
installed in two actual buildings. The configurations of these
systems are summarized together with their performance

Viscoelastic (VE) dampers were first utilized in the Twin World
Trade Center Towers in New York City for wind induced building sway
in 1969. In the 1980's, the Columbia SeaFirst and Two Union Square
Buildings in Seattle utilized dampers for wind. In 1994 the
Chien-Tan railroad station roof in Taipei, Taiwan utilized VE
dampers to reduce wind induced vibrations. Recent seismic studies
at several universities have demonstrated the benefits of VE dampers
for steel and concrete structures. Full scale VE damper dynamic
testing has met peer review requirements for retrofit installation
of a 13 story steel moment frame building in Santa Clara County in
1994. The results of university testing and building application
installations are reviewed in this paper. (Authors' abstract).

Active control. Active fin systems. Wind structural vibrations.

response control.
Various types of active control systems have been proposed in order
to reduce wind-induced structural variations. The objectives of
this control is to increase structural safety from some distorting
damages while limiting the amplitude of building motion to within
the range of the occupants' sense of safety. An active fin system
has been proposed by authors, and from the preliminary experimental
tests, it has been assured that this system is considerably
effective for reducing wind-induced structural vibrations. In this
paper, more practical investigations for the active fin system are
executed in both wind tunnel tests and natural wind tests. The
active fin adopted here is an up-to-date control device designed as
installing to practical structures. The basic concept for
developing this device is to aim to control structural response
effectively for all directions on a horizontal plane. From wind
tunnel tests, three issues are discussed: 1) Estimation for
practical control forces supplied by the active fin; 2) Construction
of effective control algorithms for the active fin system; 3)
Examination of control effects by using the active fin. Next, those
results are applied to the natural wind tests. Two-dimensional
active control tests are executed for the full-scale active fin
under practical strong wind. (Abstract adapted from text).

Eccentrically braced frames (EBFs) designed improperly can develop
undesirable large inelastic link deformations where energy is
dissipated at only a few floors. This unsatisfactory behavior can
be caused by ill proportioning of the links. Cases drawn from both
analytical and experimental studies are discussed to illustrate the
unacceptable seismic behavior in EBFs with incorrectly proportioned
links. A design procedure for avoiding such behavior, which
illustrates a correct selection of links and the corresponding
behavior of the EBFs, is explained. Primary emphasis is placed on
the link strength distribution along the height of the EBF and its
desirable effect on inelastic link deformations throughout the
structure. (Adapted from authors' abstract).

The research focuses on the behavior of two manufactured houses under
simulated wind loads. Extensive instrumentation was employed to
insure the collection of data that would enable the determination of
the influence of interior wall arrangements. Both concentrated and
uniform lateral loads were applied to the test structures. The
concentrated loads were applied at transverse (shear) wall locations,
one load at a time, to evaluate the in-place stiffness of the loaded
wall in relation to the other walls. Uniform lateral loading to
simulate wind load was cycled up to loads of approximately 25 psf.
Finally, as much as 75 psf lateral pressure was applied in an attempt
to fail the units via racking (lateral) deflection of the shear
walls. The results of the tests and the analyses of the system
behavior are reported. The implications of the results for current
and future design procedures are discussed. (Authors' abstract).

Full scale models. Cyclones. Wind loads. Static lateral loads.
Load transfer paths. Uplift. Damage. Deflection. Data reduction.
Load spreading.
A method to determine the response of full scale houses to cyclonic
wind loads is presented. It entails the use of hydraulically
actuated rams to apply simulated wind loads. The test method uses:
1) static non-destructive lateral loads to determine load transfer
paths within the structure; 2) cyclic uplift and lateral loads to
determine the susceptibility of components to deterioration or
fatigue under repeated loading; and 3) overload to failure for
comparison with equivalent laboratory tests. Throughout the tests,
the applied loads and resulting deflections were monitored to
facilitate the structural analysis and interpretation of the data.
This paper critically examines the test method and indicates areas in
which further improvements can be made. (Author's abstract).

Nonstructural components.
Laboratory tests have shown that conventional internal lining
materials, when fastened according to engineering specifications, can
be used as a bracing medium against horizontal wind forces. The
bracing strength of gypsum plasterboard is approximately proportional
to the length of the wall, but there is only an 85 percent gain in
cladding two faces rather than one. Tests on a full scale brick
veneer house have shown that even nominally non-structural walls have
the capacity to brace the structure more efficiently than
conventional diagonal bracing. The tests demonstrate that ceilings
and roofing material also provide lateral bracing. In some instances
the brick skin can provide racking resistance but there was no
evidence of racking force transfer between the brickwork and the
timber frame to which it was attached. (Author's abstract).

Seismic response analysis. Base isolated buildings. Reinforced

Sendai, Japan Test Facility.
This paper investigates the response characteristics of full-size
reinforced concrete buildings via numerical simulations and actual
observations. The test facility consists of two identical
three-story buildings constructed side by side at Tohoku University
in Sendai, Japan. Since the installation of high-damping isolation
bearings in April 1989, data from over twenty earthquakes have been
recorded. In this paper, three representative earthquake records are
used to study the detailed response characteristics. Numerical
simulations are carried out with the system response program, SISEC.
Results indicate that the advantage of the isolation system for small
earthquakes is insignificant. For relatively large earthquake
motion, however, the effect of isolators in mitigating the
acceleration response becomes more pronounced. Both analysis and
observation demonstrate that the isolation system installed in the
Sendai Building is very effective; stiff enough to prevent building
displacement under minor earthquakes and wind loads, yet capable of
reducing the acceleration response during moderate and strong ground
motion. (Authors' abstract).

In this paper, a full-scale, three story, wood frame building was
subjected to lateral loads to investigate the response to seismic and
wind loads. The influence of the shear stiffness of a diaphragm and
that of a bearing wall perpendicular to the load direction are
investigated. The experimental results are compared to those
calculated from the finite element model, the frame model, and also
on Tuomi's model based on the load-slip relations of a nail joint.
The applicability of these calculation methods to the design
procedure is also discussed. (Adapted from authors' abstract).

and subsequent analytical predictions. This paper discusses the
results from the work on hollow-core prestressed precast diaphragm
floors subjected to in-plane shear forces. The in-plane shear
strength and stiffness of such floors are very important to the
overall stability and behavior of masonry buildings subjected to
earthquake and wind loads. This paper discusses the comparative
parametric comparisons resulting from 16 full-scale tests of plank
floor slabs. (Authors' abstract).

lateral loads were applied to the test structures. The concentrated
loads were applied at transverse (shear) wall locations, one load at
a time, to enable evaluation of the in-place stiffness of the loaded

simulate wind load was cycled up to approximately 25 psf. Finally,
more than 70 psf lateral pressure was applied in an attempt to fail
the units via racking (lateral) deflection of the shear walls.
Subsequent to the full-scale testing, racking tests were performed on
individual walls constructed following the same plans and

Researchers in the determination of wind loads on structures have
long known far more of the structure of the wind than has been used
by the design engineer. Full-scale tests of structures, both of
local pressures and of structure response, have been scant because of
a shortage of funds and because of difficulties associated with the
experimental techniques. At the same time structures are being
designed and built. The firm of Skilling, Helle, Christiansen,
Robertson has been engaged in the design of several tall buildings
ranging in height from 500 to nearly 1800 feet above the ground in
which both theoretical and experimental techniques used for
developing pertinent data of wind velocity and air temperature, the
simulation by wind tunnel models (both pressure and aeroelastic
models) and the synthesis of the wind data with the wind tunnel
measurements. The report attempts to summarize the techniques now
used by engineers in evaluating wind effects on buildings and
structures. (Authors' abstract).

Taller structures subject to wind forces and other dynamic loads
require a more sophisticated engineering approach to analysis and
design. In particular, the interaction of wind forces and building
responses demands attention to the inter-relationship between the
aerodynamics of turbulent wind streams and the building response
characterisitics. The interrelationships between the spectral
components of wind, the macro-geometry of tall structures, and the
micro-geometry of structural components should be understood as
random phenomena and treated by probabilistic methods. To cope with
the mathematical complexities of highly non-linear interactions
presents a formidable difficulty, if not an insurmountable task.
Wind tunnel testing of physical models is now a frequent practice.
Ultimately, however, both the mathematical modeling and the wind
tunnel test practice need prototype corroboration. The Atlanta
studies should provide vital information on building behavior. The
Atlanta investigation involves a full-scale experimental study of the
effects of wind on a 23-story steel office building. The building is
to be instrumented with pressure transducers, differential
displacement gages, and accelerometers at four elevations in addition
to an optical tracking system. Wind data to determine velocity
profiles are obtained from anemometers in the proximity of the
building. Local wind speeds are measured by means of anemometers
atop a 75-foot mast erected on the roof of the building and at three
elevations on a TV transmission tower one-half mile from the site in
the direction of the prevailing winds. Local ground-level winds will
be studied by means of portable anemometers. (Adapted from authors'

distribution. Boundary layer velocity field. Natural wind.
Experimental values obtained in wind tunnel tests on model-scale
buildings have been applied to building design in every country.
However, as the nature of natural wind was investigated in detail,
the difference and similarity between wind pressure distribution on
full-scale buildings in the natural wind and that on models in a
constant velocity field became an important problem. One of the
problems of similarity is that the natural wind has vertical
distribution and its velocity is not constant as is that in a wind
tunnel. Researchers in laboratories in every country notice this and
are trying to obtain useful results using the boundary-layer wind
tunnel. In the present investigation, grids of horizontal rods were
placed at a varying spacing in a wind tunnel in order to produce the
vertical distribution of wind velocity, which is expressed in terms
of V = V sub o times the nth root of h/h sub o, where V sub o is the
velocity at the reference height h sub o. Wind pressure distributions
on model-scale buildings were obtained in this wind tunnel, varying
the height, the width, the depth, and the wind direction. The
results were obtained in the cases of n = 4 and n = 8 because the
velocity distribution of the natural wind can be expressed in the
above equation by varying n from 4 to 8. Besides this, in order to
compare the results, a large-scale model, which was 3.6 meters high,
1.2 meters by 1.2 meters in plan, was placed on the shore and wind
pressure distribution was measured during a strong wind. (Author's

adopted the laser displacement meter, long period vibration detector
and micro-pressure transfer operation. During the year 1981-1983,
when the structure faced multiple typhoons, we adopted for the first
time the laser pressure indicator, together with the optical guided
fiber to test the structure. At that time, the testing result was
very satisfactory. The significant result of wind pressure and

EEA Abstract:
This paper discusses full-scale data on the dynamic properties of buildings in Japan. First, it
introduces the Japanese database on dynamic properties of buildings (JDDB) collected by the
Committee on Damping Data (CDD) of the Architectural Institute of Japan (AIJ). All data
contained in the database have been amended as a result of detailed questionnaire studies to
literature authors, designers and building owners to confirm the measured values, and to obtain
necessary information. The database also includes additional important data on the building and
damping evaluation procedure. Reliable data have consequently been selected for more than 250
buildings and are contained in the database. Next, it discusses the natural frequencies and
damping ratios in a low-amplitude regime based on JDDB. Some other important statistics on
damping ratios and natural frequencies of buildings in JDDB are also discussed. Finally,
nonlinear behavior of the dynamic properties of several buildings varying with vibration
amplitudes is demonstrated and discussed. Precise analyses are still being made. As examples of
database analyses, damping characteristics in the low-amplitude regime for steel structures,
steel-reinforced concrete structures, and reinforced concrete structures are presented. More
analyses are necessary, but a simple formula was found to be valid for the damping ratio in a
reinforced concrete building in the low-amplitude regime. From the results demonstrating
nonlinear characteristics of dynamic properties of buildings, the importance of secondary member
effects both on stiffness and damping was recognized. An accurate predictor model for damping
needs to be established to aid designers in estimating damping ratios based on building
properties. To achieve this, establishment of a high-quality database by international
collaboration is a pressing need.

EEA Abstract:
Various types of active control systems have been proposed in order to reduce wind-induced
structural variations. The objectives of this control is to increase structural safety from some
distorting damages while limiting the amplitude of building motion to within the range of the
occupants' sense of safety. An active fin system has been proposed by authors, and from the
preliminary experimental tests, it has been assured that this system is considerably effective
for reducing wind-induced structural vibrations. In this paper, more practical investigations
for the active fin system are executed in both wind tunnel tests and natural wind tests. The
active fin adopted here is an up-to-date control device designed as installing to practical
structures. The basic concept for developing this device is to aim to control structural
response effectively for all directions on a horizontal plane. From wind tunnel tests, three
issues are discussed: 1) Estimation for practical control forces supplied by the active fin, 2)
Construction of effective control algorithms for the active fin system, 3) Examination of
control effects by using the active fin. Next, those results are applied to the natural wind
tests. Two-dimensional active control tests are executed for the full-scale active fin under
practical strong wind.

EEA Abstract:
Viscoelastic (VE) dampers were first utilized in the Twin World Trade Center Towers in New York
City for wind induced building sway in 1969. In the 1980's, the Columbia SeaFirst and Two Union
Square Buildings in Seattle utilized dampers for wind. In 1994 the Chien-Tan railroad station
roof in Taipei, Taiwan utilized VE dampers to reduce wind induced vibrations. Recent seismic
studies at several universities have demonstrated the benefits of VE dampers for steel and
concrete structures. Full scale VE damper dynamic testing has met peer review requirements for
retrofit installation of a 13 story steel moment frame building in Santa Clara County in 1994.
The results of university testing and building application installations are reviewed in this
paper.

A number of active control systems have been developed, fabricated and installed in full-scale
structures and they have been subjected to actual wind forces and ground motions. The focus of
this paper is on the observed response of several of these systems. They include an active
bracing system and an active mass damper system installed in a six-story experimental building,
and two hybrid mass damper systems installed in two actual buildings. The configurations of
these systems are summarized together with their performance characteristics. Observed
performance of these systems during actual wind storms and moderate earthquakes shows that they
meet their basic design objectives. Furthermore, their performance can be adequately predicted
through simplified analytical and simulation procedures.

EEA Abstract:
A passive control device made of a viscoelastic material, a bitumen/rubber compound (BRC), is
proposed to reduce the response of tall buildings to low to medium seismic or wind loads. The
BRC damper has the following features: (1) it can be shaped into a sheet of any thickness, (2)
the material has strong adhesive qualities and can adhere without any bonding agent, (3) it
induces a large viscous shearing reaction against shearing deformations, (4) it can sustain
large shearing. To determine the effectiveness of the BRC damper for vibration control, a
dynamic loading test was conducted. The coefficients of equivalent viscous damping and shearing
stiffness for a nonlinear spring-dashpot model were found. The accuracy of the established
values was confirmed by a random wave dynamic loading test. Next, the effectiveness of passive
control devices with BRC for a full-scale structure was studied through a numerical analysis of
a simulated 24-story building with a floor area of 2800 sq m on each story. Two devices made of
the BRC compound were set up on each story. The results are discussed.

diaphragm and that of a bearing wall perpendicular to the loading direction on the structural
performance was investigated. The experimental results were compared with the calculation from
the finite element model, frame model, and also Tuomi's model based on the load-slip relations
of a nail joint. The applicability of these calculation methods to the design procedure was

EEA Abstract:
This report describes a combination of analytical and field studies performed for a medium
highrise office building with precast concrete cladding. These studies investigated the role of
the building facade in adding lateral stiffness and resistance to wind and moderate earthquake
loadings to the entire structure. Analytical models were used to study the influence of cladding
on building frequencies and linear seismic response, and finite element studies to determine the
role of cladding connection details and panel support conditions. Experimental studies were
performed on two 24-story steel frame structures to quantify theoretically demonstrated effects
and to confirm analytical models. On the first building, ambient vibration measurements were
taken before, during, and after installation of cladding, and modal response results obtained.
On the second, full-scale forced vibration tests were performed to determine 12 bending and
torsional frequencies and mode shapes. System identification methods were used to estimate
stiffness parameters associated with the core, exterior frame, and cladding stiffness. Studies
of overall building response to earthquake ground motion were performed to determine the
relation of clad and unclad model frequencies to the frequency content of the ground motion. A
simple panel failure model was proposed and results of localized cladding failure were
determined. The usefulness of such studies in understanding curtain wall behavior and improving
curtain wall design is discussed.

EEA Abstract:
Base isolation has been proposed as an economical approach to aseismic design for many types of
buildings and structural systems. In general, the base of a structure is isolated when a support
system with extremely low horizontal stiffness limits the transmittal of horizontal shear from
the ground to the structure. The displacement of such a structure under wind loading will,
however, be excessive since the horizontal stiffness of the support system is so low. The
horizontal deflection of a building with an isolated natural frequency of 0.5 Hz would, for
example, be 4 in. for a wind load of one-tenth the weight of the building. While such a
horizontal deflection would not be acceptable, a base isolation system could be equipped with a
mechanical fuse which would be sufficiently strong to resist wind loading, but which would
fracture during an earthquake, leaving the building free on the isolation system. In this
report, the authors describe an extensive series of shaking table tests of such a device. The
wind restraint consisted of a notched shear pin. Several shear pins were tested in conjunction
with a natural rubber isolation system placed beneath a three-story 40,000 Ib steel frame model
structure. Pins with breaking forces ranging from 3% to 20% of the weight of the model were
tested. The model structure was subjected to various peak accelerations of three earthquake
inputs. The shear pins fractured rapidly and cleanly. The breaking force for each pin was
reasonably predictable. Although higher mode accelerations were induced in the model structure
when the pins broke, these disappeared rapidly. The design of a shear pin mechanical fuse system
for a full-scale structure is discussed at the end of this report in view of the experimental
results described.

EEA Abstract:
Tests were carried out on a single-family, detached house to determine its deflection
characteristics under lateral loads. The house was a two-story building of conventional woodframe construction. Two series of tests were conducted. The first of these was to determine the
stiffness of the house when subjected to a simulation of wind loading. The second was to
determine the dynamic response of the house to a single impulse load.
