摘要
对一具有抗拉功能的新型叠层橡胶隔震支座抗拉机构(简称新型抗拉机构)进行加工设计,并将加工后的新型抗拉机构安装于一钢框架结构模型的基础底部,进行地震模拟振动台试验,考查4条地震波作用下的结构反应。对试验结果的分析表明:新型抗拉机构具有良好的减震效果、耗能性能及抗拉承载力,且其基本力学性能受拉力的影响不大。
This paper designs a new type of rubber bearing with tensile properties （referred to as the new tensile mechanism） , and install it on the basis of a steel-frame structure model for seismic simulation shaking table test to examine the structure＇s response under 4 seismic waves. The results show that the new tensile mechanism has good damping effect, energy dissipation performance and tensile capacity, and its basic mechanical properties are not greatly affected by the tensile force.
