The paper describes a fiber based analytical model of unbonded post-tensioned precast concrete walls with vertical joint connectors. The model is used in an analytical study of the influence of selected wall design parameters on the lateral load behavior of a prototype wall. The paper verifies the accuracy of a trilinear idealized lateral load behavior based on the derived closed form expressions based on the results of the analytical parameter study. Recommendations based on the trends observed in the parameter study are provided to help the designers satisfy the criteria of the proposed design approach.
