It was focused on the structural design of the northern part. By comparison with the twotower structure with a common podium and single tower structure, the main performance of the towers was gained, the law of seismic force transmission between tower and podium was found. The temperature effect on the super long structure was analyzed by simulating the construction sequence. The buckling analysis on cross-level columns was done to guarantee the stability of columns. The detailed finite element analysis on the zone which the shear wall changes into columns was done to guarantee the safety of the structure.Keywords: super high-rise building; seismic-expansion joint; two-tower structure with a common podium; cross-level column; super long structure; shear wall change into columns; finite element analysis作者簡(jiǎn)介：吳國勤，碩士，設(shè)計(jì)總監(jiān)，高級(jí)工程師，一級(jí)注冊(cè)結(jié)構(gòu)工程師，Email：wu.guoqin@ccdi.com.cn。參考文獻(xiàn)［1］中建國際設(shè)計(jì)顧問有限公司.合肥華潤中心38號(hào)地塊工程超限高層專項(xiàng)審查送審報(bào)告［R］. 2012.［2］傅學(xué)怡, 吳兵, 孫璨，等.卡塔爾某超高層建筑結(jié)構(gòu)設(shè)計(jì)研究綜述［J］.建筑結(jié)構(gòu)學(xué)報(bào),2008,29(1):1-9.［3］傅學(xué)怡, 吳國勤, 黃用軍，等.平安金融中心結(jié)構(gòu)設(shè)計(jì)研究綜述［J］.建筑結(jié)構(gòu),2012,42(4):21-27.［4］傅學(xué)怡，吳兵.混凝土結(jié)構(gòu)溫差收縮效應(yīng)分析計(jì)算［J］.土木工程學(xué)報(bào)，2007,40(10):50-59.
