【摘要】 复杂的超限高层建筑结构需要进行弹塑性分析和计算来验证"大震不倒"的设防要求。以深圳某复杂超限高层建筑工程为背景,对其进行弹塑性时程分析,研究该结构在地震下的抗震性能。该工程曾用Perform-3D,ABAQUS和Ls-DYNA进行动力弹塑性时程分析。对三个程序得到的结构在罕遇地震作用下的整体反应指标和构件损伤情况进行了对比,结果表明,三个程序得到的整体反应计算结果基本吻合。更多还原

【Abstract】 Inelastic analysis need to be used to prove the safety of complex high-rise building structure under rare earthquakes.An inelastic time history analysis was carried out on a complex high-rise building located in Shenzhen,and the seismic performance under different level earthquakes was studied in detail.Three computer programs—Perform-3D,ABAQUS,and Ls-DYNA were used to build analysis model and carry out time history analysis.The results were concluded in two levels,the entire structure response and the damage information of elements.Detailed results quantified the damage degree of this structure under rare earthquake,and verified that this structure would not collapse under rare earthquake.更多还原
