多高层建筑体系中,上部结构、基础和地基共同作用的问题很早就引起了人们的重视。由于这一体系的复杂性和计算条件的限制,不少学者根据不同的计算目的,提出了很多简化模型和相应的算法。通过实际工程,借助SAP2000建立有限元模型,对各种简化模型进行分析比较,得出各种简化模型的优缺点;通过比较筏板基础厚度、地基土的刚度等因素对筏板受力机理的影响,得到筏板基础优化设计的依据。
In many high-rise building systems, the problem of the interaction between superstructure, foundations and foundations has long attracted people’s attention. Due to the complexity of this system and the limitation of computing conditions, many scholars put forward many simplified models and corresponding algorithms according to different calculation purposes. Through the actual project, the finite element model of SAP2000 was established to analyze and compare various simplified models, and the advantages and disadvantages of various simplified models were obtained. By comparing the thickness of raft foundation, the stiffness of foundation soil and other factors, Influence, get raft foundation optimization design basis.
