Numerical Model and Seismic Performance of Cable-sliding Friction Aseismic Bearing
摘要
Abstract
The developed cable-sliding friction aseismic bearing was designed by using the concept of friction energy dissipation and displacement restriction device. Numerical model of this bearing was simulated based on experimental results. Different continuous beam bridge models with different support restraints were established. The effects of seismic mitigation were compared. Some parameters including the initial free movement and the friction coefficient in the bearing model were analyzed. The results show that application of the cable-sliding friction aseismic bearing can reduce the earthquake internal force of fixed pier. The initial free movement and the friction coefficient can be properly increased to improve the effect of seismic mitigation.关键词
