| 摘 要： | 针对大连国贸中心大厦的结构分析计算,探讨超高层结构平面布置对结构抗震性能的影响。对环带腹杆分别按桁架单元和梁单元进行分析,梁单元比桁架单元产生的应力大很多;通过比较弹性分析以及弹性和弹塑性时程分析,探讨了连梁刚度折减对结构抗震性能的影响。罕遇地震作用下核心筒墙体和巨柱拉力的衰减规律,说明了超高层结构设计中地下室结构构件应模拟实际边界条件进行分析。

| Abstract: | Aiming at building structure analysis of Dalian China World Trade Center,the influences on structural seismic performance were discussed for high-rise structural layout.The band belly bar was analyzed respectively according to the truss element and beam element,the stress of beam unit is much higher than truss element.Through the elastic analysis as well as the elastic and elastoplastic time-history analysis comparison,the coupling beam stiffness reduction effects on the seismic behavior were discussed.Under rare earthquake lag attenuation law of core tube wall and a giant column explains that super high-rise structure design of basement structure of components should simulate the actual boundary conditions. |
