Effect of Vehicle Vibrations on The Dynamic Response of Inclined Bridge Spans

Abstract

This research work deals with the bridge vehicle interaction problem. A software program was used to solve this dynamic problem using the substructuring & matrix condensation concepts. This program was found to give excellent performance in terms of accuracy and efficiency. A parametric study was performed on Al Kilo 21 bridge including the different factors affecting this interaction such as the bridge entrance and exit slopes, vehicle speed, bridge continuity, bridge damping, and the existence of bumps at bridge entrance and expansion joints. Another design was performed by Author for the studied bridge to study the effect of the bridge construction type on DAF values. The bridge was designed as steel beams acting with the concrete slab as a composite section and a comparison was made between DAF values for both types of bridge.
