In this study, a new precast concrete (PC) beam-column joint of moment resisting frame applicable for moderate seismic regions is proposed. A semi PC beam-column connection with U-shaped strands is developed in a n attempt to improve workability and provide effective stress transfer mechanism at the joint. The structural system consists of PC beams w ith U-shaped strands, PC columns, PC slabs, and topping concrete. A seri es of three interior and three exterior semi PC joint specimens was tes ted to investigate the structural behavior of the system subjected to th e lateral cyclic load. Key test variables are the number of strands placed in the PC beam and the presence or absence of the transver se reinforcements at the connection. The experiment and performance evaluation of the system were conducted in accordance with ACI T 1.1-01 (2001). According to the test results, the proposed structural s ystem with transverse reinforcements at the joint is sufficient to use in moderate seismic regions.
