摘　　要：对某刚度和质量均不对称的超高层双塔连体结构体系采用SATWE,ETABS和ANSYS三个软件进行了计算和分析。三种软件计算所得的结构总体特征信息和反应基本相同。在静力荷载作用下,三种软件的计算结果表现出较高的一致性,在计算地震反应时其结果仅存在细微差异,沿双塔连体方向的变形和受力受地震作用控制,垂直方向则受风作用控制。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.
