An experiment of three T-shape beam-column steel joints with intensive cover plate was conducted under low cyclic loading with different cycle numbers, to study seismic performance of the joints subjected to long-period ground motions. Effects of cycle number on mechanical performance and length of plastic hinge were analyzed. The results show that as the cycle number increases, capacity of the joint decreases, and plastic hinge of the joint develops longer which appears closer to the cover plate, and the platform of skeleton curve grows longer, and the stiffness attenuates slightly.
