剪力键对摩擦摆式支座减隔震效果的影响
Effect of shear-key on seismic isolation effect of FPB
摘要
Abstract
Taking a continuous beam bridge in the highly seismic region of the eastern Guangdong Province as an example, the numerical simulation method for the FPB with shear-key was put forward. Based on the full-bridge finite element model, the effect of shear-key on seismic isolation effect of FPB was analyzed by using the numerical simulation method. By changing relevant parameters of FPB, the influence of the shear-key with different parameters on the isolation of FPB was investigated. The results show that when the friction coefficient of FPB is small and the radius of curvature is large, the shear-key has a great influence on the bending moment of the pier base. It is necessary to consider the influence of the shear-key in the seismic response analysis.关键词
