| 摘 要： | 文章采用动力弹塑性时程分析方法评估某对称双塔大底盘超限高层结构在罕遇地震作用下的抗震性能和能力,了解其动力特性、屈服机制和破坏特征,并检验了关键薄弱部位的抗震安全性。计算结果显示该结构具有较强的抗震承载力,呈核心筒剪力墙连梁的＂梁铰破坏＂特征,达到了＂大震不倒＂的抗震设防目标。

| Affiliation: | Seismic performance and capacity of a large-base-slab and twin-tower tall building is assessed in this pape,by the way of dynamic elastic-plastic history analysis.The dynamic characteristics、yield mechaniand and destroyed form of the structure are learned,and the anti-seismic security of the key weak positions ane tested.The resultes show that the earthquake resistant abilities of the structure are good,plastic hinges formed at coupling beams of shear walls.It can fulfill the seismic fortification criterion ＂no collapse under severe earthquake＂. |
