Steel frame-steel plate shear wall system consists of frame beam and framecolumn, steel plate shear wall structure. Steel plate shear wall with frame beam to resisthorizontal load, the steel plate shear wall ACTS as a main component to resist lateralforce;-the top frame steel plate shear wall structure system, a continuous steel plateshear wall as a web, in-plane stiffness is very big, has the very high initial stiffness,along with the horizontal load increases (The level of lateral) lateral, fills in steel plateforming resistance band (the larger film tension), improve the resistance to lateralstiffness and bearing capacity, etc.In actual engineering, as a plate of steel plate shear wall is thick, the waste ofmaterials and increase the weight. For structure design of both economic and reasonableand can obtain good performance, is proposed in this paper and a half just answer-withsupporting steel plate shear wall structure system, the structure of plate and supportgood synergy, when the load is not supported for sheet provide effective out-of-planeconstraint, improves the initial stiffness, when load to larger, gradually formed anumber plate diagonal tension band, provide effective support of out-of-planeconstraints; Through the synergy between plate and support before and after, make thiskind of structure system has good static and dynamic performance.Based on half just answer-with supporting steel plate shear wall structure system,this paper, ANSYS finite element software structure model for nonlinear static analysisand time history response analysis, completed the following content:?1?half just answer-with changed parameters of steel plate shear wall structure modelfor the nonlinear static finite element analysis, studies the support form, cross ratio,thickness, support the section size of the influence of structural stiffness and bearingcapacity of law; The analysis results show that the "X" type support structure than '?'and monoclinic stiffness of the support structure and high bearing capacity; When thecross ratio is four thirds, the tensile strength of the plate with best development; At thesame time, the thickness, the size of the support section is also the major effect of thestructure performance parameters.(2) the "X" to support one and a half across a layer just answer steel frame-supportsteel plate shear wall structure with reciprocating loading, the analysis of the structure of the hysteretic performance; Results show that the structure of the hysteresis loopback is full, energy dissipation good performance.(3) for three and a half across nine layers' X 'support just answer steel frame-supporting steel plate shear wall structure system and half just answer-braced framestructure system has carried on the time history response analysis, comparative analysis,studied the structure of energy consumption.Overall, with steel plate shear wall is a kind of effective component to resist lateralforce, has high bearing capacity and good ductility performance; Under the seismicaction, and a half just answer steel frame-support this kind of steel plate shear wallstructure system than half just answer steel frame-supported shear wall seismicperformance is good, better energy performance.
