This paper elucidates the seismic behavior of side-plate moment connections to box columns, which are most common in Iranian structures, for use in steel moment-resisting frames. In typical connections, the most severe stresses occur where the beam joins the column. This is also the weakest location in the assembly and, as a result, stresses are locally intensified at this location. Side-plate has a lot of benefits, such as; no need for continuity plates in box sections, which is a challenge in the construction phase.Results of an analytical investigation of the cyclic behavior of 10 models, with side plates between the IPE beam and the box-column, are presented in this paper. The analysis was conducted using the ANSYS 5.4 software. The results indicate that this connection type has sufficient stiffness, strength and ductility to classify it as a rigid, full-strength, ductile connection.
