［摘要］北京麗澤金融商務(wù)區(qū)F02，F(xiàn)03地塊工程為一大底盤多塔結(jié)構(gòu)，地下室部分連為一個整體，地上為兩個結(jié)構(gòu)單元。本工程為超限高層，其中的F02-2，F(xiàn)03雙塔高裙房連體單元結(jié)構(gòu)較復(fù)雜，存在超高及立面收進超限問題，且兩個塔樓連接較弱，在設(shè)計中采用SATWE，MIDAS，PERFORM-3D程序進行了多遇地震、設(shè)防地震、罕遇地震下的分析，并考慮了整體計算中出現(xiàn)的裙房范圍剪力缺失問題，針對裙房剪力墻較少問題補充了裙房分塊計算，對兩個塔樓弱連接處進行了樓板應(yīng)力分析。結(jié)果表明，本工程結(jié)構(gòu)體系可以滿足預(yù)定抗震性能目標(biāo)，采取的各種措施合理，結(jié)構(gòu)安全可靠。

Abstract:The buildings in F02 and F03 plots in Beijing Lize Financial Business District are multi-tower buildings with a large podium. The structural basement of the project is connected into a whole, while the above ground structure is divided into two structural parts. The project is an out-of-code high-rise building, and the structure of twin-tower high-podium connecting structure formed by F02-2 tower and F03 tower is complex, which has out-of-code items of height and facade income, and the connection between two towers is weak. SATWE, MIDAS and PERFORM-3D programs were used to carry out analyses under the frequent earthquake, precautionary earthquake and rare earthquake respectively in the design. The problem of the lack of shear force in the podium range was considered in overall calculation. The number of shear wall is very small in the podium range, to the problem, the podium block model calculations were added. The floor stress analysis in weak connection between two towers was carried out. The results show that the structural system can meet the intended seismic performance objectives, the various measures adopted in the design are reasonable, the structure is safety and reliability.
Keywords:Beijing Lize Financial Business District； multi-tower structure; out-of-code design; performance objective
