Research On The Elasto-plastic Analysis Model Of Steel Plate-concrete Composite Shear Walls

Composite steel plate reinforced shear walls developed by the steel plate shearwalls, steel plate and concrete is made of the new component to resist lateral force.Composite steel plate reinforced shear walls is better than the same size of thereinforced concrete shear walls in shear stiffness, ultimate bearing capacity and goodductility performance. Because of its section and mechanical performance is morecomplex, so the finite element analysis has its own particularity. At present,the finiteelement analysis of steel plate reinforced shear walls’s work has just developed, andalso has no special literature about composite wall’s finite element model is establishedand analyzed.Current research for composite steel plate reinforced shear wall’s design methodmainly through three ways: earthquake examples,experimental study and numericalsimulation analysis. The existing domestic earthquake damage of steel concretecomposite shear wall instance basically in a blank state,Experimental study subject tothe conditions of test equipment, make full scale test is hard to do, even if the scaleexperimental study its not the big amount. So finite element program is used to establishsteel plate concrete composite shear wall calculation model and carries on the numericalsimulation analysis as an important supplement of the experimental study is particularlyimportant.In view of the above problems, this paper’s main work are as follows:(A) analysisof the existing domestic and foreign composite steel plate reinforced shear wall’s testphenomenon, summarizes the typical composite wall’s mechanical characteristics andfailure modes.(B) summarizes the existing finite element simulation of the compositesteel plate reinforced shear wall’s work.(C) using the finite element program ls-dynacreate the composite steel plate reinforced shear wall’s modle, and analysis the wholeprocess of nonlinear analysis of composite wall, and to achieve the following results:①in the one-way static loading, to calculate the limit bearing capacity of compositewall, have the whole process of force-displacement curve.②according to the finiteelement simulation,get the composite wall’s whole process of mechanical condition andthe main failure parts.(D) compared the finite element analysis results and theexperiment results.Through the above work, provide the basis for experiments of subsequent research, and lays the foundation for finite element dynamic analysis and provide the reference.
