[摘要]大连城市经纬项目存在凹凸不规则、部分竖向构件及刚度不连续、楼板开洞等情况,对结构整体性及连接处受力极为不利。为了保证结构的整体性,在两个设备层处加强连接,设备层连接处上下层相关范围采用钢支撑桁架加强。采用SATWE,ETABS,ABAQUS软件对结构进行了弹性和弹塑性分析,分析了结构不规则部位对整体结构的影响,并对结构进行了性能化设计。结果表明,结构性能能够达到预期目标及规范要求。[关键词]结构不规则; 连接部位; 弹塑性分析; 性能化设计中图分类号:TU318 文献标识码:A 文章编号: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
