| 摘 要： | 对软土地基上的超高层建筑空间巨型框架提出了一种新的简化分析方法.将空间巨型框架结构中的辅助框架柱只考虑其轴向刚度,沿巨型框架梁的轴线方向连续化后,作为巨型梁单元的文克弹性地基,把巨型梁按文克弹性地基梁来处理,然后将巨型柱和巨型文克弹性地基梁组成空间巨型框架,在考虑了地基的弹性变形后,用矩阵位移法进行位移和内力计算.算例计算结果表明:新的简化方法是合理的、可行的.

| Abstract: | A new simplified analytical method was developed for analysis of interactions on the soil,the foundation and the superstructure of a super tall building with a space mega frame.That is,the space mega frame structure of a super tall building was simplified as a composition consisting of the mega columns and gieders supported on elastic subgrades,and interactions between the soil and the foundation and the superstructure of the model were analyzed by matrix displacement method.The computing results show that the new simplified analytical method is rational,useful and some constructive conclusions are obtained as well. |
