(深圳市建筑設(shè)計研究總院有限公司, 深圳 518031)［摘要］合肥要素大市場建筑平面開洞較多，立面開大洞并層疊出挑，多處存在大跨度及長懸挑結(jié)構(gòu)。結(jié)構(gòu)多項指標超限，為多重復(fù)雜高層建筑。通過設(shè)定適用于本工程的性能目標，采用基于性能的設(shè)計方法對結(jié)構(gòu)進行了計算分析，采取了有針對性的抗震加強措施。分析結(jié)果表明，工程能滿足“小震不壞，中震可修，大震不倒”的抗震設(shè)防目標。此外，針對工程的特殊性，對層疊出挑結(jié)構(gòu)、連體結(jié)構(gòu)和超長結(jié)構(gòu)亦進行了詳細分析和多方案比較，分析結(jié)果表明工程結(jié)構(gòu)設(shè)計是安全可行的。［關(guān)鍵詞］連體建筑；大跨度；斜柱；桁架；舒適度中圖分類號：TU318+.2文獻標識碼：A文章編號：1002-848X(2011)04-0074-05Structural design of Key Element Market in HefeiWang Bigang, Wang Qiwen, He Xiaoxue, Huang Jianyu, Hu Kai(Shenzhen General Institute of Architectural Design and Research Co., Ltd., Shenzhen 518031, China)Abstract: Key Element Market in Hefei is a complicated high-rise building with several features, such as big holes in plane and elevation, long span and large cantilever components, cantilever length increasing layer upon layer. Several performance indexes of the structure have exceed the limit of the code. Suitable seismic performance target was set, calculation analysis was done with seismic performance design method, and strengthening measures were applied based on analysis results. Analysis results show that the structure performance can meet seismic performance target. Several plans were studied on the structure for its complexity of increasing cantilever length layer upon layer, connected tower and superlong dimension. Comparative analysis shows that the plan applied on the structure is feasible, safe and suitable.Keywords:connected building; long span; slanted column; truss; comfortableness作者簡介：王必剛，一級注冊結(jié)構(gòu)工程師，Email:wangbigang1984@163.com。參考文獻［1］方小丹, 韋宏，陳福熙，等. 上海世博會中國館國家館結(jié)構(gòu)設(shè)計與研究［J］. 建筑結(jié)構(gòu), 2009, 39(5)：84-89.［2］宋志剛. 基于煩惱率模型的工程結(jié)構(gòu)振動舒適度設(shè)計新理論［D］. 杭州: 浙江大學(xué), 2003.
