Changes in Bridge Deck Flutter Derivatives Caused by Turbulence
This paper discusses some of the results of a wind tunnel study that tested the aeroelastic stability of section models in smooth and gusting flow. Wind gusts several times longer than...
Seismic Behavior of a Full-Scale K-Braced Steel Frame?Part I Gross Behavior
As a part of the U. S. -Japan Cooperative Research Program Utilizing Large-Scale Testing Facilities, a six-story, 2 by 2 bay, concentrically K-braced steel building was constructed in...
Seismic Behavior of a Full-Scale K-Braced Steel Frame?Part II Local Behavior
The full-scale six-story concentrically K-braced steel building was subjected to Miyagi-Ken-Oki simulated earthquake whose peak intensity was 500gal. Local behavior of the test building...
Building Identification: Needs and Means
The need to conduct 'system identification' of existing buildings by nondestructive testing is discussed. A recommended flow-chart is exemplified. Existing dynamic...
Slab Participation in Frames under Lateral Loads
A unique opportunity to study slab participation was afforded by the U. S. -Japan Cooperative project on large scale testing. The data obtained from the full-scale 7-story building tested...
Earthquake Response Simulation Capacity of Pseudo Dynamic Testing?Experimntal Demonstration and Analytic Evaluation
The response accuracy of the pseudo dynamic test was evaluated from the shake table and pseudo dynamic tests conducted for a two story steel braced frame model. The obtained responses...
Evaluation of Seismic Strengthening of an Existing Building Using Base Isolation
This paper summarizes a study performed by Englekirk and Hart, Inc. to evaluate the feasibility of using base isolation to seismically upgrade an existing highrise building. To realize...
Earthquake Response of Five Story Reinforced Concrete Masonry Test Building
In 1986, a full-scale five story reinforced masonry test building is to be constructed in the Japan Building Research Institute Large-Scale Structure Test Laboratory, and through 1987...
Stress-Strain Behavior of Grouted Hollow Unit Masonry
Experimental results from axial stress-strain tests including post-peak response on hollow unit masonry prisms are compared to those of previous researchers....
Full Scale Tests of Cladding Components
A full scale, six story, steel frame at the Building Research Institute, Tsukuba, Japan was constructed for a series of projects in the U. S. -Japan Cooperative Research Program. This...

This article presents a technique for adapting current modal testing procedures to shaker table tests commonly used for qualification tests of nuclear and space related equipment. It involves...
Problems of Spectral Analysis in Dispersion Tests
The use of dispersive surface waves and spectral analysis methods is new to the nondestructive testing of airfield pavements. Such tests are to determine whether mechanical properties...
A Discrete Model for the Estimation of the Elastic Abutment Stiffness
The purpose of this paper is the presentation of a simple method for the estimation of the abutment stiffness. In this method, the abutment is represented as a uniform rigid plate with...
Comparative Seismic Response of Damped Braced Frames
The behaviours of braced steel building frames with friction joints and with eccentric bracing, under seismic forces, are compared. Nonlinear time history dynamic analysis is used. Friction...
Effect of Seismic Wave Inclination on Structural Response
A new procedure is developed using the computer program SASSI to evaluate the effects of inclined propagating shear waves on three-dimensional seismic soil-structure interaction (SSI)...
Soil-Structure Interaction at the Waterfront
In 1981 the Naval Civil Engineering Laboratory (NCEL) undertook a review of available material models. Comparison was made between test data and model predictions. Based on this study,...
