By elastic time-history analysis, Pushover analysis and elastic-plastic time-history analysis, elastic and elastic-plastic properties of two structures were investigated. Results show that both of two structures can satisfy Code for seismic design of buildings（GB 50011—2001）of “not be damaged under frequent earthquake, can be repaired under fortification earthquake and not be collapsed under rare earthquake”. The seismic performance of two structures was also compared.Keywords: super-tall building; steel structure; hybrid structure; elastic-plastic analysis作者簡介：許秀珍，高級工程師，一級注冊結(jié)構(gòu)工程師,Email:chnmaje@163.com。
