本文介绍某学校框架结构的基础隔震分析与设计。通过对非隔震框架结构和隔震框架结构固有特性的分析比较,得出隔震支座能够延长建筑结构的周期。采用7条时程波对框架结构进行中震下的时程分析,隔震结构的动力响应比非隔震结构大幅度降低,说明在地震作用下,隔震支座形成了良好的耗能机制,可以消耗相当一部分的水平地震作用,使主体结构承受的水平地震力显著降低,提高了整体结构的抗震性能。对隔震结构进行罕遇地震时程分析,并对隔震支座进行罕遇地震作用下的验算和隔震支座支敦进行罕遇地震设计。
This article introduces the basic isolation analysis and design of a school’s frame structure. By analyzing and comparing the inherent characteristics of the non-isolated frame structure and the isolated frame structure, it is concluded that the isolated frame can prolong the period of the building structure. The time-history analysis of the frame structure with seven time-history waves is carried out. The dynamic response of the isolated structure is greatly reduced compared with that of the non-isolated structure. It shows that the earthquake-resistant bearings form a good energy dissipation mechanism , Can consume a considerable part of the horizontal seismic action, so that the main structure of the horizontal seismic force to significantly reduce the overall structure to improve the seismic performance. The rare earthquakes of the isolated structure are analyzed, and the rare earthquakes of the bearing of the isolated bearing are carried out under rare earthquakes.
