A simple model for the lateral behavior of wood‐framed shear walls with stud uplifting is presented. The single‐story wall has five degrees of freedom: (1) the shear rotation of the frame; (2) two relative rotations of the sheathings; (3) the uplifting of the windward stud; and (4) the uplifting of the windward panel. For walls of two or more stories, two additional degrees of freedom are introduced for relative rotations of the sheathings in higher stories, bringing the total unknowns to seven. Results from this model are compared with the available test results. The present model is also able to show the dependence of the load‐deflection curve on the vertical load.
