The Interaction Analysis Of The Space Frame-raft-soil Foundation

The interaction analysis of the space frame-raft-soil foundation is one method of all design, whose theoretic research and practical application just start on .The article is emphasized on researching the characters of the structural internal force and displacement considering the interaction of space frame-raft-soil foundation under vertical loads. Some conclusions of interaction are derived from the research. The main researches are outlined as following:(1)In this article, through the analysis of ANSYS procedure, the finite element model of space frame-raft-soil foundation is created. The model can analyze the characters of the structural internal force and displacement considering the interaction of space frame-raft-soil foundation under vertical loads.(2)Adopting layers horizontal isotropic elasticity half-space ground model, according to the Kirchhoff theory of Small deflection of thin slab,through the analysis of ANSYS procedure,analyze the raft board foundation on the elastic ground.(3)In this article, the 3D static model is used to calculate the internal force in ground and foundation for different loads, thickness-raft , raft board concrete intensity on elastic ground. The conclusions getting through different data of space frame-raft-soil foundation and some cases are expected to be of referential use to practical engineering design.
