Study on Raft and Superstructure Column Internal Force of Tall Building with Podium and Soil Due to Interaction
-
摘要: 用理论模型和有限元方法,研究不设置沉降缝和后浇带时在高层建筑、裙房和地基共同作用情况下,地基反力的扩散对筏板弯矩和上部结构框架柱内力的影响。计算结果显示,共同作用和地基反力扩散对筏板整体弯矩有很大的影响,在总弯矩中,整体弯矩有时起主要作用;上部建筑框架柱内力也有很大变化,底层柱弯矩,剪力有大幅增加。Abstract: Through finite element analisys method, the model of internal force distribution of raft foundation and superstructure column is set up. It is obtained that the moment of raft and superstructure column is mainly dependent on the global raft bending.
