摘要
提出了一种应用形状记忆合金拉索耗能器复合普通橡胶支座的新型建筑结构隔震体系,给出了该隔震支座的详细构造,并通过分别运用该隔震支座和普通橡胶支座的8层隔震建筑的时程仿真分析,比较两种装置的减震、隔震效果,验证了应用形状记忆合金在高层建筑结构智能隔震方面的有效性与适用性.
In this paper, an intelligent isolation system of highrise building structures applying shape memory alloy (SMA) cables and laminated rubber bearing is proposed,and the constructional detail of the intelligent isolator is presented. Based on the timehistory emulation analysis for the highrise building structures under earthquake excitations, the isolation effects are compared respectively by applying the intelligent isolator proposed and the conventional rubber bearings.The result demonstrates the significant effectiveness and feasibility of the isolator based on SMA in the intelligent isolation for highrise building structures.
