某超高层框架-核心筒结构弹塑性时程分析

Nonlinear time-history analysis for a super high-rise frame-tube structure

采用建研数力开发的弹塑性动力时程分析软件SAUSAGE,建立了某实际超高层钢筋混凝土框架-核心筒结构的有限元分析模型。在此基础上对该框架-核心筒结构进行了罕遇地震作用下的弹塑性时程分析。利用SAUSAGE软件的非线性计算能力和后处理功能,获得了最大层间位移分布、楼层剪力分布和各类构件的损伤分布与发展等多项结构地震响应结果。分析结果表明,结构在罕遇地震下具有良好的抗震性能,能够满足"大震不倒"的设防要求。

A practical super high-rise reinforced concrete frame-tube structure was modeled by numerical analysis software(SAUSAGE) which was newly-developed by BRSC. Then seismic responses of the structure under major earthquakes were analyzed by nonlinear time-history analysis method based on the numerical structural models. The structural responses of storey drift,storey shear-force and structural damage distribution and development were obtained due to the excellent calculation ability and post-processing function of SAUSAGE software. The analysis results show that the structure has good seismic performance and can meet the requirements of no collapse under major earthquakes.
