In addition, a new reinforcing method to perforated section steel plates of joint was proposed to simplify the construction of the joint. It is proved that the reinforcing method is convenient and feasible through tests.Keywords: transfer joint; finite element analysis; perforated reinforcement作者簡介：何東，碩士，助理工程師，Email：hedong@gzdi.com.參考文獻［1］王維俊，周定，王松帆，等. 廣州琶洲PZB1401地塊項目結(jié)構(gòu)設計［J］．建筑結(jié)構(gòu)，2012,42（6）：47-52.［2］ 04SG523型鋼混凝土組合結(jié)構(gòu)構(gòu)造［S］. 北京：中國計劃出版社，2003.［3］GB 50017—2003鋼結(jié)構(gòu)設計規(guī)范［S］. 北京：中國計劃出版社，2003.［4］鋼板疊合周邊焊接穿孔補強方式研究報告［R］. 廣州：華南理工大學，2010.
