Aspects of Wind and Earthquake Dynamics of Cable-Stayed Bridges

by Robert H. Scanlan, Johns Hopkins Univ, Baltimore, MD, USA,



Document Type: Proceeding Paper

Part of: Bridges and Transmission Line Structures

Abstract:

In the course of dynamic analysis of long-span cable-stayed bridges for the effects of earthquake and wind, a number of observations have been made that may be of interest to designers. In particular, some expected effects of strong earthquake motion upon tower leg design and deck-tower interaction are mentioned. Some needed precautions and methods necessary to ensure stability under wind are also underlined.
