3‐D Nonlinear Seismic Behavior of Cable‐Stayed Bridges
Publisher: American Society of Civil Engineers
Abstract: The dynamic behavior of three‐dimensional (3‐D) long‐span cable‐stayed bridges under seismic loadings is studied. The cases of synchronous and nonsynchronous support motions due to seismic excitations of these flexible ...
Lateral Earthquake Response of Suspension Bridges
Publisher: American Society of Civil Engineers
Abstract: The lateral response of suspension bridges to multiple‐support seismic excitations is investigated. A frequency‐domain random‐vibration approach is utilized to take into account not only the differences in ground motion ...
Analysis of Behavior of Earth Dam Using Strong‐Motion Earthquake Records
Publisher: American Society of Civil Engineers
Abstract: The seismic records of the Long Valley Earth Dam are utilized in order to shed some light on the salient features of the dam nonlinear behavior. The dam is well instrumented with 22 accelerographs tied with a common ...
Ambient Vibration Studies of Golden Gate Bridge: II. Pier‐Tower Structure
Publisher: American Society of Civil Engineers
Abstract: Dynamic characteristics such as natural frequencies, mode shapes, and damping ratios of the Golden Gate Bridge tower were determined using ambient vibration data. The ambient vibration tests involved the simultaneous ...
Ambient Vibration Studies of Golden Gate Bridge: I. Suspended Structure
Publisher: American Society of Civil Engineers
Abstract: Extensive experimental investigations were conducted on the Golden Gate Bridge in San Francisco, California, to determine, using ambient vibration data, parameters of major interest in both wind and earthquake problems, ...
Importance of Cable Vibration in Dynamics of Cable‐Stayed Bridges
Publisher: American Society of Civil Engineers
Abstract: The present study deals with the dynamic behavior of cable‐stayed bridges when the vibration characteristics of the stay cables are taken into consideration. Such complex vibrations are strongly coupled with the bridge ...
Nonlinear Free Vibrations of Suspension Bridges: Theory
Publisher: American Society of Civil Engineers
Abstract: A general theory and analysis of the nonlinear free coupled vertical‐torsional vibrations of suspension bridges with horizontal decks are presented. Approximate solutions are developed by using the method of multiple scales ...
Nonlinear Free Vibrations of Suspension Bridges: Application
Publisher: American Society of Civil Engineers
Abstract: The basic characteristics of the nonlinear free flexural‐torsional vibrations of two suspension bridges are examined. The Golden Gate Bridge and the Vincent‐Thomas Bridge were chosen to represent both a relatively long‐and ...
Torsional Earthquake Response of Suspension Bridges
Publisher: American Society of Civil Engineers
Abstract: The earthquake‐induced torsional response of suspension bridges when subjected to multiple support excitations is analyzed in the frequency domain by means of random vibration theory. Appropriate rocking and torsional ...
