摘要
文章建立了超高层建筑束筒结构与其基础、地基共同工作的三维半解析分析模型,也就是将超高层建筑束筒结构等效连续化为一个支撑在半无限大弹性地基上的具有连续分布质量特性的加劲薄壁筒组合体。文献中的算例结果表明:模型的简化是合理的、可行的。并总结出了一些切合实际且很有意义的结论,从而为超高层建筑束筒结构的整体分析计算提供了一种可行的分析方法。
A semi-analytical three-dimensional model of interactions between the subgrade and the foundation and the superstructure of a super tall building bundled-tube structure was established, which is a combination of stiffened-thin-walled tubes having continuous distributing mass on the semi-infinite elastic subgrade. The results of computing example imply that the simplified semi-analytical model is effective and reasonable according to referenee [2] and [3]. Some reasonable and significant conclusions are obtained by analyzing the computing results. Thus, a new method for the dynamic analysis of the interactions is developed.
