摘要:
以某跨海连续梁桥为例,研究动水压力对拉索减震支座减隔震体系下深水桥梁地震响应的影响,分析拉索减震支座在深水区连续梁桥中的适用性。首先建立考虑动水压力下的深水桥梁地震响应分析方法,然后针对拉索减震支座减隔震体系对该桥进行动力响应分析,并与摩擦摆减隔震体系进行对比。结果表明:动水压力增大了深水桥梁的地震内力和位移响应; 拉索减震支座减隔震体系下,动水压力对地震响应的影响程度明显小于摩擦摆减隔震体系,体现了拉索减震支座在深水桥梁抗震设计中的优越性。
Abstract:
A continuous girder bridge across sea was taken as an example to study the effect of hydrodynamic pressure on seismic response for deep-water bridges with cable-sliding friction bearing system. The applicability of cable-sliding friction bearing system in deep-water continues beam bridges was analyzed. The seismic response analysis method of deep-water bridges under hydrodynamic pressure was firstly established, and then the dynamic response analysis of the bridge with cable-sliding friction bearing system was carried out. The comparison was made with the friction pendulum system. The results showed that the hydrodynamic pressure increased the seismic internal force and displacement of deep-water bridges. The influence of hydrodynamic pressure on seismic response under cable-sliding friction bearing system was obviously less than that under friction pendulum system, which showed the superiority of cable-sliding friction bearing in seismic design of deep-water bridges.
