Abstract：The seismic performance evaluation of a high-pier long-span continuous rigid frame bridge is an interesting and formidable issue in seismic analysis of bridges. An elastic-plastic seismic response analysis was put forward based on its characteristics. The simulation of the seismic response of bridge under severe earthquake was carried out by using the plastic hinge element in the text and finite element program on hand. With the intensity of earthquake up to which caused the fracture of the bridge, the elastic-plastic seismic response analysis of a high-pier long-span continuous rigid frame bridge in the west was realized, and some available conclusions such as the failure mode, the greatest intensity that bridge could afford were got, which were useful to the seismic design.
