摘要:
为了研究钢筋-沥青隔震层的材料与几何非线性震动特性,对钢筋-沥青隔震结构进行了振动台试验,分析了结构在不同加速度幅值输入时的隔震性能。同时,在钢材的应力-应变关系基础上,考虑构件竖向力的二次矩效应,提出了钢筋-沥青隔震层骨架曲线的计算方法,并结合双线型恢复力模型的滞回规则,建立了相应的恢复力模型。利用建立的恢复力模型,编制程序进行了弹塑性时程分析,并与试验结果作对比。结果表明:当钢筋-沥青隔震层的受力钢筋进入弹塑性阶段时,隔震层能够吸收大部分地震能量,显著降低上部结构的地震反应;弹塑性时程分析结果与试验结果吻合较好,由此建立的恢复力模型准确并且适用,可为钢筋-沥青隔震层的工程设计与非线性地震反应分析提供参考。
Abstract:
In order to investigate the material and geometrical nonlinear vibration characteristics of the steel-asphalt seismic isolation layer,shaking table tests were carried out on the steel-asphalt seismic isolation structure,and the isolation performance of the structure under different acceleration amplitudes was analyzed.Meanwhile,on the basis of the stress-strain relationship of steel,considering the second moment effect caused by the vertical force,an algorithm of the skeleton curve of the steel-asphalt seismic isolation layer was proposed.And according to the hysteretic rules of the bilinear restoring force model,a corresponding restoring force model was established.The elastoplastic time history analysis was made by programming with the established restoring force model,and the results were compared with the experimental results.The results are as follows.When the steel bar in the steel-asphalt seismic isolation layer reaches the elastoplastic stage,the isolation layer can absorb most of the seismic energy and significantly decrease the seismic response of the superstructure.The results of elastoplastic time history analysis are in good agreement with the experimental results,and the established restoring force model is accurate and appropriate,it can provide reference for engineering design and nonlinear seismic response analysis of the steel-asphalt seismic isolation layer.
