To expedite construction of small precast concrete buildings using dry joints, this study developed and evaluated a connector system for solid slabs. The research included a comprehensive literature review on seismic design requirements for precast concrete floors, followed by an analytical evaluation of the connector's bearing capacity in 3-story buildings. Experimental assessments were conducted to determine the in-plane and out-of-plane capacities of the newly designed semi-circular connector. Finally, the constructability of both the semi-circular and flat connector configurations was compared through tests on single-story precast concrete frames.
