Abstract


Superstructure and foundation together is an emerging discipline . With the rapid development of the high-rise building in recent years , has become a hot issue in the theoretical research and engineering practice . In the conventional design , the upper structure and foundation as the independent structure calculation does not consider the interaction between the upper structure , the basis and foundation , there is a big difference with the actual structure of the force and deformation designed to make the structure unsafe or uneconomical . This article summarizes the basis of the research methods and results at home and abroad on the issue of the superstructure and foundation together , focus on the vertical load and wind loads , the structure of the mechanical properties of the space frame , raft foundation interaction and mechanical properties of the space frame , raft foundation interaction problem using the finite element method to simulate and analyze . In this paper, the completion of the following work : (1) made ??a comprehensive analysis of interaction theory introduced ; ( 2 ) the use of the cohesion of the substructure , superstructure and raft foundation , foundation interaction coupling analysis model : (3) using the finite element method , the characteristics of the force on the raft foundation , internal force variation analysis and exploration .
