摘要
简述了桥梁震害的特点,论述了支撑连接件在桥梁抗震中的重要意义,以大同至呼和浩特公路山西境大同至右卫段高速公路鹊儿河大桥为算例,从墩顶弯矩、墩顶位移、支座变形等几个方面研究了HDR高阻尼隔震橡胶支座的减隔震性能,并与普通板式橡胶支座进行了对比分析,为桥梁抗震在连接件的选择上提供了指导性意见。
This paper briefly described the characteristics of bridge seismic damage, discussed the important significance of supporting connection piece in the bridge seismic.Taking a bridge of Dahu expressway as an example, it also studied the seismic isolation performance of HDR high damping seismic isolation rubber bearing from the pier top bending moment, pier top displacement, bearing deformation, and other aspects.Through comparing and analyzing with the common plate rubber bearing, it also provided guidance for the choice of connecting pieces of the bridge seismic.
