［摘要］大連城市經(jīng)緯項目存在凹凸不規(guī)則、部分豎向構(gòu)件及剛度不連續(xù)、樓板開洞等情況，對結(jié)構(gòu)整體性及連接處受力極為不利。為了保證結(jié)構(gòu)的整體性，在兩個設(shè)備層處加強連接，設(shè)備層連接處上下層相關(guān)范圍采用鋼支撐桁架加強。采用SATWE，ETABS，ABAQUS軟件對結(jié)構(gòu)進行了彈性和彈塑性分析，分析了結(jié)構(gòu)不規(guī)則部位對整體結(jié)構(gòu)的影響，并對結(jié)構(gòu)進行了性能化設(shè)計。結(jié)果表明，結(jié)構(gòu)性能能夠達到預(yù)期目標及規(guī)范要求。［關(guān)鍵詞］結(jié)構(gòu)不規(guī)則; 連接部位; 彈塑性分析; 性能化設(shè)計中圖分類號：TU318 文獻標識碼：A 文章編號：1002-848X(2016)09-0014-05
Complex structural design of Dalian City JingweiLi Dongfang, Wang Lichang, Liu Nan, Qiu Xuguang(Dalian Institute of Architectural Design Co., Ltd., Dalian 116021, China)Abstract: There exist irregular concave and convex structures, partly vertical elements and stiffness discontinuities, floor openings and so on in Dalian City Jingwei project, which is extremely unfavorable for structural integrity and the connection mechanism. In order to ensure the structural integrity, strengthening measures are taken at two device layers. Steel support trusses are adopted in the relevant ranges of the connection parts of upper and lower device layers to strengthen. Programs of SATWE, ETABS and ABAQUS were used to conduct elastic and elasto-plastic analyses on the structure to analyze the impacts of structural irregular parts on the overall structure. In addition, performance-based design was carried out on the structure. Results show that the structural performance can achieve desired objectives and regulatory requirements.Keywords: structural irregularity; connection part; elasto-plastic analysis; performancebased design
