STUDY ON EQUIVALENT CALCULATION MODEL OF CORRUGATED STEEL PLATE SHEAR WALL UNDER PURE SHEAR LOAD
By using the combination of theoretical analysis and numerical simulation,this paper puts forward an equivalent calculation model suitable for elastic and elastic-plastic analysis of corrugated steel plate shear wall:based on the principle of initial stiffness equivalence,the concept of initial stiffness ratio between refined model and equivalent model is proposed,and the material properties of the equivalent model are modified by the initial stiffness ratio.The design of the elastic equivalent model of corrugated steel plate shear wall is transformed into the design of the formula for calculating the initial stiffness ratio.Combined with numerical simulation,the design of elastic-plastic equivalent model of corrugated steel plate wall is transformed into the design of elastic-plastic skeleton curve of corrugated steel plate shear wall,and the design formula of relevant parameters of skeleton curve is fitted.The design theory of elastic-plastic equivalent model of corrugated steel plate shear wall is given.
