某塔楼基于性能抗震设计

摘要

A tower's overrun situation had been judged and its seismic performance goals had been determined based on the ideas of performance-based seismic design.The tower's seismic performance finally had been assessed by elastic analysis of small earthquake,not yielding of shock and supplementary analysis of the elastic time.The conclusion of this paper based on the experience of the performancebased seismic design provides a reference for the similar engineering.%简述了基于性能抗震设计思想,判断塔楼超限情况,确定抗震性能目标,并通过对某塔楼进行小 震弹性分析、中震不屈服分析和弹性时程补充分析,对其结构抗震性能进行评估.最后,总结该塔楼基于性能抗震设计的经验,为同类工程设计提供参考.
