In this paper,the seismic design of a continuous beam bridge in high seismic intensity area is an engineering example. The seismic de-sign of the bridge is carried out by using the friction pendulum isolation bearing. The finite element software is used to analyze the dynamic char-acteristics of the bridge. The analysis shows that the application of friction pendulum bearing can effectively reduce the displacement of pier top and bottom moment,and make the structure design more easy to meet the requirements of seismic code.
