摘要
佛山集成金融广场建筑高度199.88m,为超A级建筑高度建筑。结构设计采用了框架-核心筒结构,对结构进行罕遇地震下的弹塑性时程分析,检验结构在大震下的抗震性能,采用ABAQUS软件对其进行动力弹塑性分析,研究在预估罕遇地震作用下结构的非线性动力响应,并给出定量评价,包括结构变形特征、楼层剪力、最大层间位移角和剪力墙损伤等。结果表明,此结构形式具有较好的抗震性能,能够保证大震不倒的抗震性能目标,整体结构设计安全可靠。
The Foshan Integrated Financial Plaza with architect height of 199. 88 m is beyond the A-level height limit of the code. The framework core tube is adopted in the structural design. Dynamic elasto-plastic analysis was carried out by sofeware ABAQUS to analyze the nonlinear dynamic responses of the structure. The quantitative evaluations were given including the structure deformation characteristics,storey shear force,maximum interlayer displacement angle and shear wall plastic damages. The results show that this structural form has well seismic performance and can ensure the performance target of not collapsing under rare earthquake. The overall structural design is safe and reliable.
