Abstract
In this report, a macro model was proposed to predict the ultimate strength of shear walls in the limited case, where the yield of the longitudinal reinforcement in tension column and of the vertical reinforcement in wall was accompanied by. It was disclosed that the ultimate strength of shear walls after flexural yielding could be well estimated by this macro model. Also, an equation was obtained by this macro model to estimate the horizontal reinforcement ratio which the ultimate strength did not increase on and after in spite of the increase of horizontal reinforcement. In addition, the ductility of shear walls after flexural yielding could be roughly estimated by using the calculation results of this macro model as parameter.
