【摘要】 对台北市附着管线的某12层钢结构建筑物(其附着管线包括横管与立管两部分)进行了抗震性能分析.深入研究与分析了附着管线的抗震性能以及管线与主体结构两者在地震作用下的相互耦合作用.为了比较分析计算结果的可靠性,分别利用Ansys以及Sap2000两种有限元软件对该附着管线钢结构进行了地震响应的反应谱分析和时程分析,得到了钢结构附着立管以及横管在地震作用下的内力响应结果,同时针对横管几何形式的变化组合进行了优化选择,得出组合形式最佳的横管几何尺寸.分析结果为该类结构合理设计和布置附着立管与横管提供了参考依据.更多还原

【Abstract】 Some 12-floor steel structural building is attached with the pipelines in Taibei,including the horizontal pipes and vertical pipes.Seismic performance of the main structure and attached pipelines has been studied.For comparative reliability of the analysis result,different finite element software has been separately used to carry on the response spectrum analysis and the time-history response analysis,and obtain inner forces of the steel structure attached with the horizontal pipes and vertical pipes under earthquake.At the same time,the optimized choice has been carried on in view of the changing combination of the horizontal pipe’s geometry forms,and obtains the best geometry size of the horizontal pipes.Finally it provides some beneficial conclusions and suggestions for the structural optimization design.The results provide a reference for the design of similar structures.更多还原
