空间高层框架—十字交叉基础梁与桩土地基相互作用分析

Analysis of Interaction between Space Multistory Frame Grillage Foundation with Piles and Soil

本文将空间高层框架—十字交叉基础梁与桩土地基结构体系简化为桩土支承的十字交叉“剪弯梁”体系,按能量变分法求解。并通过算例讨论了该结构体系若干相互作用的机理,供设计人员参考。

In this paper,the structure system of space multistory frame-grillagefoundation beams resting on piles and soil is simplified as a grillage of“shearbending beams”resting on piles and soil,and is solved by the energyvariational method.The interaction mechanism is also discussed through nu-merical examples.The results presented in this paper may serve referencesfor engineering design.
