摘要
结合一栋大底盘多塔框支剪力墙超限高层建筑的结构设计过程,针对项目超限情况,采用基于性能目标的抗震设计方法,讨论了结构不同部位的抗震等级,探讨了整体模型与分塔模型的包络设计。通过大量的计算分析以及严格的抗震措施,确保了结构在地震作用下具有良好的抗震性能。
Based on the structure design process of a frame supported shear wall structure with multi-tower and large chassis, for the conditions of beyond code limits, the performance-based seismic design method was adopted, the concept of different parts of the structure with different seismic grade was proposed, the envelope design of overall model and tower model was discussed. Seismic performance is ensured through a lot of calculation and strict aseismatic measures.
