Shear Wall as a kind of structure system is used widely, but the research on its anti-seismic behavior is deficient for this structure system in the large factory building. According to the demand of《Code for Seismic Design of Building》 (GB50011-2001 ),furthermore, based on the experimental study of two 1/15 reduced-scale shear wall models under low frequency cyclic and reversed lateral loads, the interacting behavior of the R.C frame column and the shear wall is studied, the failure mechanism and energy dissipation mechanism of moderate and tall shear wall with R.C frame column are compared, the seismic behavior is evaluated by the comparison of strength, stiffness, ductility, restoring force characteristics as well as energy consumption ability. It was showed by the experimental results that the earthquake resistant energy dissipation ability of the shear wall with frame column is satisfactory.Based on the experimental studies and calculated analysis, nonlinear finite element analysis of R.C. shear wall with frame column under unilateral load is carried out by ANSYS program in order to understand the evolution of crack patterns, deformation and failure course of the specimens in theory computing. The finite element computing results agree well with the actual measured one.Through the analysis and compare to the model structure and the prototype structure of longitudinal shear wall in main factory building, the regular pattern of earthquake resistant behavior of this kind of structure system is obtained. So this paper puts forward some seismic design concept and detailing suggestion to this kind of structure according to CSDB.
