This paper discusses the flexural performance of precast (PCa) concrete beams under reversed cyclic loading. Static cyclic loading tests were conducted on PCa beams with different connections. The experimental parameters were types of connections, location of interface and vertical position of joints between PCa segments. The results reveal that crack distribution, opening at interface and flexural capacity were affected by the type of joints. Moreover, the failure of PCa beams was affected by these parameters as well.
