Research On Behavior Of Steel Plate Shear Wall With Cross Stiffeners

Steel plate shear wall as excellent resistance to lateral force components, steel plateshear wall with cross stiffeners has broad application prospects because the advantagesof high bearing capacity, good energy dissipation capacity, simple site operation in theselection and design on the type of steel plate shear wall. And now the irrationality ofdesign specification, the complexity of finite element analysis limit the developmentspace of steel plate shear wall with cross stiffeners. This paper bases on the systemsimulation analysis of steel plate shear wall with cross stiffeners by the finite elementsoftware, by the comparative analysis of influence parameter, puts forward reasonablesimplified model of steel plate shear wall with cross stiffeners and proves the feasibility.By comparing analysis results of the two kinds finite element analysis software, findsout the more simple and reasonable analysis method of steel plate shear wall with crossstiffeners, provides certain reference for practical design works, the main researchcontents are as follows:1) It bases on the existing pseudo-static experimental results of steel plate shearwall with cross stiffeners, in this paper, it adopts numerical simulation by ANSYS, bythe comparative analysis on the difference of framework curves, hysteresis curve,energy dissipation performance, key performance parameter, stiffness degradation andthe limits of the destruction between the two results. The analysis results show that theresults of numerical simulation and experimental are consistent, and provide the basisfor the subsequent expand analysis works.2) This paper analyses steel plate shear wall with cross stiffeners on the effect ofuniaxial load by ANSYS, researches the changes of impact parameter to the influence on the performance of steel plate shear wall with cross stiffeners. It proposes the SX-HSmodel that the width to thickness ratio of stiffener takes about10is appropriate, thethickness of stiffener is more thick than the thickness of steel plate, stiffness ratio ofstiffener to panel takes about50. By the comparative analysis of key performanceparameters, steel plate shear wall with cross stiffeners can be equivalent with unstiffendsteel plate shear wall, and get regression equation between two kinds steel plate shearwalls is linear.3) This paper takes the traditional tension diagonal simplified model revise,proposes LY-S model to simulate steel plate shear wall with cross stiffeners. It analysesLY-S model on the effect of uniaxial load and reciprocating cycle load by ANSYS, andget LY-S model can simulate steel plate shear wall with cross stiffeners, the initialelastic stiffness of LY-S model is less than SX-HS model, the two models are fittingtogether better when the thickness of steel plate is no more than7mm.4) Through the ANSYS and SAP2000respectively simulate SX-HS model andLY-S model, get analysis results of SAP2000and ANSYS are consistent, in actualdesign works, it can be used SAP2000to simulate and analyze steel plate shear wallwith cross stiffeners.
