| 摘 要： | 桥梁隔震支座在使用过程中可能受到各种水平静载作用.本文介绍了一个桥梁隔震支座的水平静力试验.在试验中,考虑了不同水平位移加载步长、持荷时间、不同的初始位移变化对支座动、静力性能的影响.说明桥梁隔震支座静力性能与动力性能存在不同,随着作用时间增加,存在明显的卸载现象;水平初位移的存在对支座滞回耗能曲线没有明显的影响.

| Abstract: | The Lead-rubber Bearing supported bridge grid in service is subjected to different kinds of static loading.A static loading test on lead rubber bearing is introuded in this paper.Horizontal static testing of a bridge isolator bearing is carried out.Effects of various horizontal displacement increments,loading duration and different initial displacements on the static/dynamic mechanical behaviors of bridge isolator bearing are considered in the course of testing. It can be observed that the static and dynami... |
