摘要
简要介绍了钢阻尼器和铅芯橡胶支座的的基本原理和力学参数,结合某框架结构,运用SAP2000对安装有阻尼器和铅芯橡胶减震支座的框架结构进行分析,并与单独设置阻尼器、单独设置隔震支座以及完全没有设置任何消能构件的同一个框架进行分析比较。分析结果表明,混合消能减震结构具有很好的消能效果,比设置单一消能构件的结构具有更加优越的消能效果,可以使目标建筑结构的抗震性能得到显著提高。
In this paper,the basic principle and mechanics parameters of the steel dampers and lead core rubber isolation bearings are introduced. The structure of the frame with a damper and lead rubber bearings is analyzed and compared with other cases by using SAP2000 software. The results show that the mixed energy dissipation structure has more effect than that of setting a single energy dissipation,which can significantly improve the seismic performance of the structure.
