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...

Adaptation of Modal Testing Procedure to Shaker Tables
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...

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,...

Nonlinear Response Combination in Seismic Analysis
Simple, approximate methods are developed to evaluate the maxima of response measures which are nonlinear functions of modal responses to seismic input. Examples for such response quantities...

An Experimental Study of Active Structural Control
An experimental investigation is made concerning the possible application of active control to structures under seismic excitation. The experimental facilities and structural model are...

Dynamic Response of Highway Guardrail Post Foundations (abstract)
The highway departments use two types of guardrail posts: a circular wood post and a steel W6 multiplied by 8. 5 post. The current specifications require the steel post to be placed in...

Seismic Isolation of Bridge Structures
Seismic isolation concept has been extensively developed and applied in New Zealand and is receiving increased attention in the United States. Two bridge projects have incorporated the...

Hysteretic Behavior of Precast Cladding Connections
A preliminary experimental study is presented which investigates the behavior of connections for architectural precast concrete cladding panels. The principal objective is to quantify...

Interdependence of Dynamic Analysis and Experiment
This paper emphasizes the importance of experimental research to the development of reliable analytical methods for predicting the behavior of structures subjected to static or dynamic...

Ambient Vibration Testing of the Foothill Communities Law and Justice Building (abstract)
This paper presents the results of two ambient vibration tests conducted on the Foothill Communities Law and Justice Center Building. One ambient test was performed in 1985. The second...

A Stochastic Source Spectrum for Engineering Application
The solution of a point source (double couple) combined with K. Aki/A. S. Papageorgiou's stochastic source model is used to establish the power spectrum at the acceleration...

Engineering Laboratories' Role in Quality
Quality construction of a quality design is one goal which Owners, Design Professionals, and Contractors can all agree is needed if the project is to be truly successful. The Engineering...

Development of Second Generation Plasticized Sulfur Binders as a Paving Material
Plasticized sulphur is produced when melted sulphur is reacted with selected hydrocarbons to produce polysulfides. These polysulfides help retain a 'polymeric'...

Procedures for Predicting Settlements in Sands
In many cases, the prediction of settlements of footings on sands involves use of empirical rules. Although many approaches are reported in the literature, the relative accuracy of these...

Structural Settlements at a Major Power Plant
The foundation design for the Intermountain Generating Station was based on comprehensive geotechnical investigations that included cone penetrometer tests, borings, pressuremeter tests,...

Large Scale Testing Facility for the Evaluation of Structural Systems Under Critical Loads
The Charles Lee Powell Structural Systems Laboratory at the University of California, San Diego, provides, with a 50 ft. high reaction strong wall and a 120 multiplied by 50 ft. box girder...
