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其是否满足抗震设防要求。以珠海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,研究该结构在地震作用下的抗震性能。采用Perform-3D建立三维弹塑性分析模型,并进行了动力时程分析,对结构在地震作用下的整体反应和构件损伤情况进行了分析和评估,用详细的量化指标验证了该结构能够在罕遇地震水平下实现"大震不倒"。结果表明,错层并不会使剪力墙成为结构受剪的薄弱环节。
Inelastic analysis need be used to prove the safety of complex high-rise building structure under rare earthquakes.An inelastic time history analysis of a complex high-rise building with staggered shear-wall located in Zhuhai was carried out,and the seismic performance under different level earthquakes was studied.Perform-3D program was used to build analysis model and carry out time history analysis.The results were concluded in the entire structure response and the damage information of elements,and quantified the damage degree of this structure under rare earthquake,and verified that this structure would not collapse under rare earthquake.The soft shear floor is not formed in the structure.
