［摘要］隔震結(jié)構(gòu)所采用的材料與傳統(tǒng)抗震結(jié)構(gòu)有很大的不同，設(shè)計(jì)方法也有差異。以抗震了設(shè)防烈度為9度區(qū)的某小區(qū)高層隔震結(jié)構(gòu)為例，重點(diǎn)介紹了規(guī)范對(duì)隔震計(jì)算分析的相關(guān)要求、豎向地震作用計(jì)算、支座計(jì)算模型選擇、支座拉應(yīng)力分析等內(nèi)容。分析結(jié)果表明，對(duì)于支座參數(shù)設(shè)計(jì)合理、各項(xiàng)指標(biāo)均能滿足規(guī)范要求的高烈度地區(qū)高層隔震結(jié)構(gòu),上部結(jié)構(gòu)地震響應(yīng)明顯降低，抗震性能也得到很大提高。

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.

Keywords: isolated high-rise building; isolation layer; shear-wall structure; bearings in tension
