Design and Planned Use of a 2-Kiloton Eccentric Mass Vibrator
High-level testing of large civil structures is usually not practical, due to structural damage considerations and available testing equipment. However, in the case of a joint American/German...
Frequency Domain Analysis of a Tank-Soil System
The dynamic response of an elastic cylindrical tank supported on a rigid base under a harmonic vertical excitation is analyzed taking into consideration its interaction with the foundation...
U.S.-Japan Coordinated Program on Masonry Research
An overview of the U. S. -Japan Coordinated Program on Masonry Research is presented. The program consists of parallel efforts in Japan and the United States to develop design methods...
Sequential Earthquake Response of an Earth Dam
Sequential earthquake-response records of the well-instrumented Long Valley earth dam (Mammoth Lake area in California) are analyzed and engineering interpretations are made. The dam,...
Importance of Phasing of Strong Ground Motion in the Estimation of Structural Response
In this paper, the influence on Fourier phase spectrum of seismic source directivity due to rupture propagation along the earthquake source is investigated. The phasing is described using...
Evaluation of Building Response Recorded During the Morgan Hill Earthquake
On April 24, 1984, the Morgan Hill Earthquake (Richter magnitude 6. 2) occurred within approximately 15 km of IBM Corporation's computer-equipment manufacturing facility located...
Dynamics of Fender and Rack Systems for Docking Ferries
A dynamic analysis of a ferry fender and rack system is developed based on the conservation of energy principle and Newton's laws of motion. The dynamics of the interaction...
A Critical Look at Building Instrumentation in Earthquake Engineering
This paper discusses different issues and requirements existing in the area of building instrumentation. Strategies and types of equipment currently being used by the United States Geological...
Dynamic Testing of Structures Using the RESCUE Technique
This paper describes the most recent phase of an NSF supported program at SRI International to develop the technique of repeatable earth shaking by controlled underground expansion (RESCUE)...
Pseudo-Dynamic Testing of Structural Components
The pseudo-dynamic testing procedure is a simultaneous simulation and control process in which inertia and damping properties are simulated and flexibility properties are acquired from...
Seismic Tests of Friction Damped Steel Frames
This paper presents the results obtained from qualification tests of a new friction damping system, which has been proposed in order to improve the response of Moment Resisting Frames...
Nonlinear Behavior of Precast Concrete Shear Walls under Simulated Earthquake Loading
This paper presents experimental and analytical results on precast concrete shear walls under earthquake loading. It was observed in both small scale models tested and the computer analysis...
Hysteretic Behavior of Composite Diaphragms
Floor systems constructed with steel-deck-reinforced concrete are described. When used to resist lateral loads these systems are referred to as diaphragms. A description of a test arrangement,...
Precast Roofs for Blast Shelters
A shallow-buried reinforced concrete blast shelter has been constructed and dynamically tested at the U. S. Army Engineer Waterways Experiment Station (WES). Three thicknesses of precast...
Field Tests of Wind-Structure Interaction
The present study was initiated to investigate the possible causes for excessive lamp failure rates on High Mast illumination towers in the State of Minnesota. The study consisted of two...
Vibration Tests of Reservoir Structures Outlet Tower and Footbridge
This paper presents a field test procedure used in determining the dynamic properties of an outlet tower and footbridge for a major reservoir. Such factors as virtual water mass, soil-structure...
Dynamic Tests of LNG Storage Tanks for Earthquake Analysis of Liquid-Tank-Pile-Soil Interaction
This paper presents a field test procedure for determining the dynamic properties of large liquid natural gas (LNG) storage tanks under operating conditions. Two methods of vibratory excitation...
Floating Bridges in Short-Crested Random Seas
Four large concrete floating bridges located in Washington State have been the subject of extensive analytical modeling for dynamic response to storm waves. The dynamic analysis of the...
