摘　　要：通过对综合离散法的推广应用，提出了进行高层钢结构建筑弹塑性地震反应分析的一种实用简化计算方法，算例对比表明，该方法具有较好的计算精度，同时可以极大地节省计算时间。Based on the popularization of the Super-FEM, a simplifled approach for analysis of elasto- plastic response of tall steel buildings subjected to earthquakes is presented in this paper. Thc accuracy of the approach is verified by a comparison with normal FEM approach through a number of numerical examples. It is found that the computing time for the analysis can be greatly reduced by employing the approach.
