摘要
将超高层建筑空间巨型框架-核心筒结构体系与其基础等效连续化为一个支撑在半无限大弹性体上的加劲薄壁筒组合体,建立了集地基、基础、上部结构为一体的三维共同工作分析模型;并以此模型,利用半解析方法讨论了该结构体系的共同工作特性。分析计算结果表明:模型的简化是合理的、可行的。
The mega frame-core tube structural system and its foundation of super tall buildings are simplified equivalently and continuously into a bundle of stiffened-thin-wall tubes on semi-infinite elastic subgrade. A three-dimensional semi-analytical model considering the interactions between the ground, the fotmdation and the superstructure is then developed. Consequently, the model is applied to analyze the mega frame-core tube structural system for super tall buildings by the semi-analytical method. The analyzing result shows that the analytical model is reasonable and effective.
