| Abstract: | Combined with the （30 ＋ 40 ＋ 30）m continuous girder bridge in ＂cross 511 Road Bridge＂ project engineering, this paper introduces the application of friction pendulum isolation bearing in bridge seismic design, focusing on the parameters selection and seismic isolation design scheme about friction pendulum bearings. Through comparative analysis of the seismic response of ordinary bearings and the friction pendulum bearings, this paper demonstrates the effects of friction pendulum bearings in bridge seismic isolation and the potential problems during the application, which can provide references for similar projects in the future. |
