【摘要】 隔震结构所采用的材料与传统抗震结构有很大的不同,设计方法也有差异。以抗震了设防烈度为9度区的某小区高层隔震结构为例,重点介绍了规范对隔震计算分析的相关要求、竖向地震作用计算、支座计算模型选择、支座拉应力分析等内容。分析结果表明,对于支座参数设计合理、各项指标均能满足规范要求的高烈度地区高层隔震结构,上部结构地震响应明显降低,抗震性能也得到很大提高。更多还原

【Abstract】 The design method and materials used in isolated structure is very different from traditional seismic structure.Taking a high-rise isolated building of fortification intensity 9 as an example,the relevant requirements of computational analysis of isolated structure in specification,the calculation of vertical seismic action,the selection of calculation model and tensile stress analysis for isolation bearings were focused on.The analysis results show that,for isolated high-rise building in high intensity region with rational design of bearing parameters and the indicators meeting the specification requirements,the seismic response of upper structure could be significantly decreased,and the seismic performance could be improved significantly.更多还原
