［摘要］對(duì)某剛度和質(zhì)量均不對(duì)稱的超高層雙塔連體結(jié)構(gòu)體系采用SATWE，ETABS和ANSYS三個(gè)軟件進(jìn)行了計(jì)算和分析。三種軟件計(jì)算所得的結(jié)構(gòu)總體特征信息和反應(yīng)基本相同。在靜力荷載作用下，三種軟件的計(jì)算結(jié)果表現(xiàn)出較高的一致性，在計(jì)算地震反應(yīng)時(shí)其結(jié)果僅存在細(xì)微差異，沿雙塔連體方向的變形和受力受地震作用控制，垂直方向則受風(fēng)作用控制。

Abstract:A triumphal arch type twin-tower structure with irregular distribution of stiffness and masses in two towers is analyzed by using three softwares, STAWE, ETABS and ANSYS. It is shown that the global characters of the structure and the response are close by three different softwares, and their behaviors show quiet similar under static loads, while there is litter difference in dynamic analysis. The earthquake is the predominant factor to deformation and inner forces in the direction of twin towers, but the wind load in the other direction.

Keywords:complicated high rise buildings; asymmetrical twin-tower structure; dynamic response; design and analysis
