In many practical engineering examples, the frame structure with transfer storey is widely used. There are some difficulties in design of this structure, including vertical facade setback or multiple towers, the bias tower and the transfer storey. The seismic performance of this kind structure was studied with dynamic elastic-plastic time-history analysis method by analyzing the nonlinear dynamic responses under different ground motion inputs and the internal force distribution of key components of the transfer storey, which provides some suggestions on the design of similar structures.Keywords: subway; transfer storey; frame structure; seismic response作者簡介：朱春明，本科，工程師，一級注冊結構工程師，Email：zhuchunming.111@163.com。參考文獻［1］中國建筑科學研究院建筑結構研究所. 深圳地鐵前海車輛段上蓋物業(yè)帶轉換層框架結構的抗震性能研究［R］. 北京：中國建筑科學研究院,2012.［2］GB 50010—2010 混凝土結構設計規(guī)范［S］. 北京：中國建筑工業(yè)出版社,2011.［3］ANIL K CHOPRA.
