In this study the cyclic lateral loading tests were performed on the hybrid precast concrete panels that are interconnected by dry joints to emulate concrete shear wall cores for a mid-rise modular building. Test results show that it is necessary to improve the details of vertical reinforcement welded to the flange of C section member to increase the lateral resistance of hybrid precast concrete panels.

To improve the wet process of concrete core wall, which is one of lateral load resisting system in high-rise modular building, the new composite panel system is developed and its structural performance under lateral load is investigated analytically.
