【Abstract】 Based on the theoretical analysis of the distortion characteristic of steel shear wall with slits,the formula of initial lateral stiffness and how to get the formula is described.By the theoretical analyses,a coefficient reflecting the influence of the slit width is gained.In addition,the reducing of lateral stiffness to steel shear wall with slits after some of the wall plate entering plastic is discussed.Through the finite element analysis to wall plate with four side fixed,this article had pointed out the influence of the vertical load,the slit parameter and so on,to the elastic buckling strength of the steel shear wall with slit,and proposed the tentative plan that enhances the work efficiency of the steel shear wall with slit.更多还原
