In seismic design procedure of precast concrete structure, it is important to assign ductility requirement on the connection element for a favorable failure mechanism. The purpose of this paper is to propose a simplified procedure to determine the required ductility of coupling beam in coupled precast shear wall for a lateral displacement ductility at the top of a structure. This study shows that an equation for ductility of cloupling beam is introduced on the basis of several basic assumption.
