The connection of discrete elements in precast concrete structures has important role in overall continuity of the building. Investigations show that most precast structure damages occur in connections under earthquake loads or other disasters. This study aims to propose a new connection in order to improve rotational loading capacity and develop a finite element model of precast wall with connections by considering all details of different parts for a contemporary connection, as well as the proposed connection. Pushover analysis is conducted for major or minor bending moment and torsion moment degrees of freedom (DOFs) to obtain the capacity of each type of connection. Four key features of concrete panels and steel reinforcements are considered to determine the effect of incremental lateral movements. Pushover results indicate a significant improvement in the maximum flexural strength of the proposed connection. Indeed, the maximum moment in the bending moment DOF is enhanced when the proposed connection is used. Consequently, the result reveals that the contemporary connection has a significant defect in terms of strength in bending moment and torsion moment DOFs.
