This paper focuses on the shear strength of multi-story precast concrete shear walls when slip at the horizontal joints has occurred. The shear resistance mechanism of the lower three stories of a multi-story precast concrete shear wall under horizontal loads was the object of this research. The shear resistance mechanism is composed of a) the total arch mechanism, b) 45-degree truss mechanism, and c) each story arch mechanism. Based on this model, a formulation procedure to calculate the shear strength of precast concrete shear walls after its horizontal joint has slipped due to horizontal loads is proposed. The validity of the model has been verified by comparing with the test results carried out in the past. The predicted values using the presented formulation show good correlations with the test results. In addition, using the formulation, it is possible to carry out a shear design for multi-story precast concrete shear walls having bending failure type predominant over other types of failure.
