Study on Energy Absorption Characteristics of Basin Rubber Bearing with Trapezoidal Steel Damper

针对在单向力作用下梯形钢阻尼器的变形情况,建立整体结构的水平力-位移表达公式,通过ABAQUS软件进行仿真,得到支座荷载-位移的滞回曲线,分析不同影响因素对支座滞回曲线的影响规律。通过地震荷载响应分析,得到地震荷载下的荷载-位移曲线,同时分析了单向与双向加载下的吸能特性。结果表明:新型支座具有良好耗能特性,可以有效地减少地震波造成的破坏。

To adress the deformation of trapezoidal steel damper under the action of one-way force,the horizontal force displacement expression formula of the whole structure is established,and the load displacement hysteretic curve of the bearing is obtained through simulation by ABAQUS software.Seismic load response is analyzed to gain the load displacement curve under seismic load,and the energy absorption characteristics under unidirectional and bidirectional loading are studied.The results show that the new bearing has good energy dissipation characteristics and can effectively reduce the damages caused by seismic waves.
