Good quality of fittings in steel structures and structural systems is integration key factor. In an intense earthquake connection problems designated as the destruction factor of many steel buildings. A poor connection can lead to series of successive and fundamental deterioration in the structural steel. With appropriate beam-to-column connections can be helped to improve the quality of construction. In this study, First, design a beam-to-column end plate connection according to american institute of steel construction. Then, to achieve purposes of this study, and according to this, in box columns welding fourth dimension continuity plate according to the implementation of these columns will not do well. As a result continuity plate will be deleted from connection of beam-to-column end plate designed. And study on the connection will do without continuity plate, Therefore, in this study, we will survey the behavior of the two connections with bolt and rod bolt under push.  In fact, here the additive load will applied on connections mentioned into two pushover and cyclic load, moment-rotation charts for pushover to each of the two connections drawn and according to the comparison charts, information about ductility, resistance and ultimate loading was obtained. Then , by placing the cyclic load on the samples achieve to intended hysteresis charts for each of the two connections. By comparing these two charts we will find that in resistance and ultimate load, rod-bolt connections are superior than bolt connections.
