Bridges are indispensable components of the infrastructure of modern society, and their assessment via techniques of structural dynamics is assuming greater importance. Seismic responses of EL-Ferdan Railway Bridge (over the Suez Canal near Ismalia city) were investigated through three-dimensional finite-element model. The Seismic analyses have been conducted from the deformed configuration due to the bridge own-weight for two cases of operation, the open position and closed position. The earthquake records were input in the bridge longitudinal, lateral, and vertical directions simultaneously. Results include dynamic characteristics, time-history, and frequency –domain responses. |
