End-plate beam-to-column connections provide a viable alternative for the moment-resisting frames in seismic design. According to many fabricators end-plate connections do not have the erection tolerances. Therefore, the beam is fabricated shorter and the gap between the end-plate and the column face in order to make fit the beam to the distance between the supporting columns. This study describes to investigate the effect on the cyclic load of the gap between the end-plate and the column flange (filled with I-shaped element) on the performance of the connection consisting of the welded plate beam and column sections. The maximum moments obtained experimentally were compared with the predicted moments. Three end-plate moment connection configurations were classified in one of three categories depending on the amount of inelastic rotation at the connections. The inelastic rotational capabilities and the moment strength of tested connections are evaluated.
