Abstract
Bridges are indispensable components of the infrastructure of modern society, and their assessment via techniques of structural dynamics is assuming greater importance. The static and dynamic behaviors of the Aswan-Canal cable-stayed bridge are investigated through a three-dimensional finite-element model. These investigations were carried out under normal stage and under assumed cracking stage. Different load cases are used for the static analysis. The seismic response analyses have been conducted from the deformed equilibrium configuration due to bridge own-weight. Two earthquake records are used in the analysis. Each earthquake record was input in the bridge longitudinal, lateral. and vertical directions simultaneously. The results show that the bridge statical system has dominant influence on the bridge vibrations and that the bridge deflection should be monitored carefully. Also, there is a strong coupling in the three orthogonal directions within most modes of vibrations. Results include static and dynamic characteristics, time-history and frequency -domain responses.
