| 摘 要： | 目前高阻尼橡胶支座在国内桥梁工程建设中使用尚处于起步阶段。本文对高阻尼橡胶支座的力学性能进行了系统的试验研究,研究了该支座的竖向刚度、水平刚度、阻尼比及水平剪切大变形等。该支座的推广应用,将使桥梁结构在地震(中震、大震)时降低地震作用力,对整体结构能进行限位,有效地控制桥梁结构的地震反应,达到桥梁结构隔震减震的目的,弥补我国桥梁结构中现在所用支座之不足,同时可降低成本,节省使用空间,便于施工。

| Abstract: | High damping rubber bearing(HDR) is starting to be used in bridge engineering in China.This report is an experimental study on the mechanical property of the HDR,including vertical rigidity,horizontal rigidity,damping ratio and the damage property of large horizontal shear deformation of this bearing.In the case of using bearing,during earthquake(especially moderate earthquake and major earthquake) the seismic force of bridge can be reduce. This bearing can also confine the displacement of the whole structure and effectively control the earthquake response of the bridge. |
