Design and Analysis of a Frame-core Wall Super High-rise Base on Seismic Performance

进行了某框架-核心筒超限高层基于抗震性能的设计分析。多遇地震下,进行反应谱分析与弹性时程分析。设防烈度地震下,进行中震弹性与中震不屈服复核。罕遇地震下,进行静力弹塑性分析(Pushover Analysis),评估结构的抗震性能,发现结构潜在的破坏机制,针对性地加强薄弱部位,改善结构抗震性能。该工程通过三个水准地震作用分析,基本实现了"小震不坏,中震可修,大震不倒"的抗震设防目标。

The design and analysis of a frame - core wall super high-rise structure based on seismic performance are conducted. Under minor earthquake response spectrum analysis and elastic time history analysis were used. Un- der moderate earthquake elasticity elastic design and non-yielding design were re-checked. Under rare earthquake, the static elasticplastic analysis （ Pushover Analysis） was used, estimate the seismic performance , find the potential failure mechanism, strengthen the weak positions seismic effect analysis through three level, meet , and improve the structure seismic the requirements of no-damage under medium earthquake, and no-collapse under strong earthquake performance. The engineering under light earthquake, repairable
