Abstract

This paper develops a model of finger expansion joints for seismic analysis of bridges. Expansion joints have been regarded as a minor structural component and they were disregarded in the dynamic response analysis of bridges. However expansion joints are extremely important structural component for controlling the seismic response of bridges. Two models are proposed in this paper. One is the model in which an expansion joint transfers only a small friction force after failure, and the other is the model in which rock of failed expansion joint results in transfer of a large lateral force. Dynamic response analysis which includes the proposed model shows that the effect of expansion joints is very important in evaluating bridge response, in particular comlumn plastic deformation at the plastic hinge and residual drift.
