ABSTRACT
In order to study the structural performance and seismic response of Chinese ancient stone arch bridge, a typical Chinese ancient stone arch bridge, the Putang Bridge, was taken as a study case in this paper. Firstly, the finite element model of this bridge was built up by the software of ANSYS according to the on-site survey and test, the structural performance of this bridge under the vertical static loads was studied, resulting in the weak parts of the whole structure under the static loads. Then, the seismic response of this bridge under different seismic wave excitations were studied, and the weak parts of this bridge under the seismic waves were obtained. The study results can provide basis and reference for scientific conservation for the similar types of stone arch bridges.
