Structural Behaviors of Cable-stayed Bridge with High Piers

Abstract

Cable stayed bridge is one of the competitive structural solution in the mountainous regions of southwestern China. However, it is particularly challenging to develop efficient system for the unpretendingly high piers. In this paper, the nonlinear finite element model of the proposed cable stayed bridge has been developed, and the static structural behavior, buckling, ultimate bearing capacity and dynamic characteristics were determined by detailed numerical analysis. Some recommendations have been proposed according to the numerical results.
