Seismic Response of Prestressed Concrete Bridge with CFST Piers

Abstract

Large span prestressed concrete girder is among the most reasonable bridge structure in the mountainous regions of southwestern China. However, it is particularly challenging to develop efficient solutions for the unpretendingly tall piers in order to across the steep gorges. In this paper, the nonlinear finite element model of the proposed prestressed concrete girder bridge has been developed, and the seismic response of the high piers of concrete filled steel tube was determined by detailed numerical analysis. Some recommendations have been proposed according to the numerical results.
