在采用了普通橡胶支座的情况下,使用有限元分析软件midascivil建立抗震分析模型对桥梁挡块进行抗震性能分析。分析结果表明采用合适的挡块刚度及挡块与梁间隙,对减轻桥梁结构的地震动力响应有着较好的效果。
In the case of ordinary rubber bearing, the seismic analysis model of the bridge block is established by using midascivil finite element analysis software. The analysis results show that the proper block stiffness and the clearance between the block and the beam have good effect on reducing the seismic dynamic response of the bridge structure.
