EVALUATION OF DEFORMATION AT SHEAR FAILURE OF REINFORCED CONCRETE COLUMN AND BEAM AFTER FLEXURAL YIELDING

Abstract

The method to evaluate deformation at shear failure of reinforced concrete columns or beams after flexural yielding is proposed. The proposed method is based on the stress condition at the critical end of members that is the equation between force action and resistant capacity on the orthogonal cross-section of the compressive strut. The advantage of this method is simple and contains the effective factors related to the deformation capacity, shear stress ratio, axial stress ratio, shear reinforcement ratio. The statistical analysis based on previous researches shows that the method has a sufficient accuracy comparing to other method.
