The effective bending stiffness of one sided stiffener in reinforced steel shear wall was analyzed. The stiffener and the plate were isolated and acted by their interactive forces along the connecting line. The plate was analyzed as loaded by in plane and out plane loads. The stiffener was analyzed as simply supported beam. The plate and the sitffener were combined to satisfy the continuity conditions in the longitudinal strains and the deflections on the connecting line, The effect of shear deformation in the stiffener was included. The buckling analysis and bending analysis of one side stiffened plates were taken. Analytic expression of the effective bending stiffness and the effective breadth was found. The effective breadth was indispensable while calculating the effect of shear deformation. The influence of shear deformation can't be ignored when the depth span ratio of the stiffener was large. Comparing with the results of ANSYS analysis, it is found that the analytic solution has excellent accuracy regardless of the shapes of the stiffener.
