Response of Aswan cable-stayed bridge to spatial non-synchronous seismic excitations

Abstract Cable-stayed bridges are important infrastructure facilities serving the world today. Therefore, their safety against earthquake ground motions is crucial. However, due to long spans, affecting seismic excitations might be spatially non-synchronous. This paper presents a study of effect non-synchronous on Aswan cable-stayed bridge located at southern Egypt. Nonlinear time history analysis was conducted three-dimensional finite element model bridge. The spatial variability represented in terms wave passage which simulated via different delay times between arrivals motion supports. Results indicated that has, general, favorable most response parameters. attributed flexibility overall provided by structural system and/or existence isolation.
