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。
The finite element analysis model of an actual super high-rise reinforced concrete frame-core tube structure is established by using the elasto-plastic dynamic time history analysis software SAUSAGE developed by several researchers. On this basis, the elasto-plastic time-history analysis of the frame-core structure subjected to rare earthquakes was carried out. Based on the non-linear calculation ability and post-processing function of SAUSAGE software, the seismic response results of many structures such as the distribution of the maximum layer displacement, the distribution of the floor shear force and the damage distribution and development of various components are obtained. The analysis results show that the structure has good anti-seismic performance under rare earthquakes and can meet the requirements for fortification of large earthquakes.
