［摘要］結(jié)合9度（0.40g）區(qū)尋甸匯龍印象住宅小區(qū)的雙塔高層結(jié)構(gòu)，介紹其隔震設(shè)計(jì)的基本步驟及隔震支座受拉應(yīng)力的控制方法。提出按同一時(shí)刻出現(xiàn)拉應(yīng)力的隔震支座數(shù)量占隔震支座總數(shù)量比例不宜超過15%的原則來進(jìn)行隔震支座布置；在對(duì)雙塔結(jié)構(gòu)模型進(jìn)行整體隔震分析的同時(shí)，對(duì)單塔模型也進(jìn)行隔震分析校驗(yàn)，并進(jìn)行包絡(luò)設(shè)計(jì)；對(duì)該雙塔高層結(jié)構(gòu)的超長樓板進(jìn)行了地震作用和溫度作用下的應(yīng)力分析，在樓板應(yīng)力變化較大及應(yīng)力集中處按分析結(jié)果進(jìn)行了板厚及配筋的加強(qiáng)。結(jié)果表明，該結(jié)構(gòu)隔震設(shè)計(jì)滿足要求。［關(guān)鍵詞］隔震設(shè)計(jì); 受拉隔震支座; 雙塔高層結(jié)構(gòu); 超長樓板中圖分類號(hào)：TU352.12 文獻(xiàn)標(biāo)識(shí)碼：A 文章編號(hào)：1002-848X(2016)11-0039-05
Isolation design of a high-rise twin towers in area of 9-level seismic precautionary intensityZhang Jianxin1, Ni Jintao1, Zhang Wensheng2, Liu Zhan1(1 Kunming Civil Institute of Architectural Design & Research Co., Ltd., Kunming 650221, China; 2 Yunnan Earthquake Damping Ann Technology Co., Ltd., Kunming 650211, China)Abstract: The high-rise twin towers in Hui-Long Impression Residential district in Xundian with 9-level seismic precautionary intensity (0.40g) was used to introduce the basic steps for isolation design and control method of tensile stress of isolation bearing. The arrangement principle of isolation bearing was presented that the quantity of isolation bearings appearing tensile force at the same time should account for no more than 15% of total isolation bearing number. Overall isolation analysis was conducted on structure model of the twin towers and the isolated check analysis and envelope design were also carried out on single tower models. Under the seismic load and temperature load actions, stress analysis was carried out on super long floor of the twin tower high-rise structure and the floor thickness and reinforcement were strengthened in positions where floor stress changes largely and there occurs stress concentration according to the analysis results. The results show that the seismic isolation design of the structure meets the requirements.Keywords: isolation design; tensile isolation bearing; high-rise twin towers structure; super long floor
