摘要:
国外对隔震结构竖向地震反应的观测结果和对隔震结构竖向地震作用计算的规定,都与我国抗震规范有较大差别。本文通过反应谱和时程分析,讨论了多层隔震结构的竖向地震作用取值及竖向地震作用效应,对我国抗震规范的有关规定作了探讨,认为除位于近断层附近的隔震建筑外,其它隔震结构的竖向地震作用可取与不隔震结构相同;对于多层隔震建筑,多遇地震下可不考虑竖向地震作用,在罕遇地震下,应对所有隔震结构验算支座是否受拉或失稳,并且组合时应计入竖向地震作用效应。
Abstract:
As to the vertical earthquake responses of the multi-storey isolated buildings,the regulations in Chinese code for seismic design of buildings are different from the investigations of the response of isolated buildings in Japan and USA seismic codes(FEMA 450).To better understand the responses of isolated buildings under vertical earthquakes,the vertical response spectrum and the time history analysis are used.The results demonstrate that the vertical earthquake loads on isolated buildings are the same with the fixed base buildings except from those in near fault.As to multi-storey isolated buildings,which have the small ratio of height-width,the results also indicate that the vertical earthquake loads do not have any effect on the responses of these buildings and can be neglected in small earthquake,while the tension and stability of bearings should be investigated including vertical earthquake loads in large earthquakes.
