（北京市建筑設(shè)計研究院，北京 100045）［摘要］介紹了需要進行超限抗震審查的空間結(jié)構(gòu)的限值和超限抗震設(shè)計中需要進行的分析工作和構(gòu)造設(shè)計要求。討論了阻尼比選取、整體分析、多點分析和支座節(jié)點的抗震性能設(shè)計，以及空間結(jié)構(gòu)的風荷載等抗震、抗風審查的重要內(nèi)容。結(jié)合空間結(jié)構(gòu)的特點，介紹了空間結(jié)構(gòu)風洞試驗和風振分析的具體要求。最后，給出了進行超限抗震審查應(yīng)提交的技術(shù)文件的內(nèi)容。［關(guān)鍵詞］空間結(jié)構(gòu)； 抗震； 抗風； 審查Seismic and wind design checking on space structureGan Ming, Zhang Sheng(Beijing Institute of Architectural Design, Beijing 100045, China)Abstract:The limited values of space structure in ultra limit seismic checking are introduced. The analysis works and details of seismic design which required in ultra limit seismic design are suggested. Items of seismic checking such as the selecting of damping ratio, global analysis, multi-support and multi-dimension excitation seismic analysis, seismic performance design of supports, wind load are discussed. The detailed demands of wind tunnel test and wind-induced vibration analysis are introduced. The contents of technical files for ultralimit seismic design checking are introduced.Keywords:space structure; seismic; wind design; checking作者簡介：甘明，博士，教授級高工，Email：ganming1@vip.sina.com。參考文獻［1］中華人民共和國建設(shè)部.高層建筑抗震審查要點［S］.
