Finite Element Analysis Of Interaction Between Superstructure Foudation And Ground

With the further development of China's opening policy, high buildings, Wide-span buildings are largely built, and at the same time, the technology of computer develop quickly, the subject of interaction between high-rise building and foundation become rapidly a new application subject. In the past, the superstructure was considered as a single element whose bottom was fixed on the foundation. Apparently this approximately approach was unsuitable well for the real structure, so the design was insecurity or diseconomy.This article has summarized the research approach and achievement of the interaction between superstructure, foundation and ground. It is emphasized on researching the characters of the structural internal force ,considering the interaction of space frame-raft-soil foundation under vertical and wind loads. Some conclusions of interaction are derived from the research."The main researches are outlined as following:(1) introduced the theory of interactive analysis relatively systemical(2) by using the equilibrium of force and the compatibility of displacement, Built coupling mode of interaction between superstructure,foundation and ground;(3)This paper puts emphasis on studying the force behavior and internal Force of raft foundation by coupling of finite element;...
