Shear Mobilization on Laterally Loaded Shafts
From the results of a pressure cell instrumented rigid shaft embedded in stiff clay and subjected to horizontal static loading the side shear mobilization rate, and its contribution to...
Seismic Acceleration Maps for Oregon
To evaluate the seismic hazard for the Corps dams in the Portland District, operating basis earthquakes (OBE) and maximum credible earthquakes (MCE) were established for seismic zones...
Seismic Resistance of an Elevated Water Tank?A Case Study
Current knowledge of earthquake risk and structural response has raised concern about the safety of elevated water storage tanks which were constructed several decades ago. This paper...
Seismic Risk Analysis of LNG Storage Tanks
This paper presents an approach to the seismic safety review of existing LNG storage tanks. The approach considers the seismic hazards from ground motion, surface fault rupture, and soil...
Attaching Steel Members to Reinforced Concrete Elements
A variety of structural systems have been devised to strengthen existing buildings for improved seismic resistance. Strengthening methods currently in use for reinforced concrete structures...
RC Structures Under Severe Loads?An Expert System Approach
The authors propose the application of expert systems to the post-test assessment of specific structural systems. In the study reported, an existing expert system shell was employed and...
New Techniques in Forced Vibration Testing
Forced vibration testing is a well established technique as indicated by references 1 to 8. This paper describes a system for forced vibration testing developed over two years during work...
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,...
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...
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...
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...
