The bending connections Beam to the Cruciform Column in Iran are increasing. Normal columns, such as columns I and H, have the ability to connect two Beams. Cruciform Columns the ability to connect 3,4 Beams. This requires a strong connection that should be considered in the design of steel structures. One of the members of the connecting Panel Zone. In the design Codes, the relationship between the yield point and final point of the panel zone in the H columns was presented.The purpose of this study is to investigate the behavior and strength of panel zone in cruciform columns. For this purpose, the modeling has been used by ABAQUS software. In the first step, numerical modeling has been confirmed with laboratory verification. In the second step, by designing and modeling 20 numerical models, the strength of the panel zone is investigated. According to the results of models, it was found that for the Cruciform Column it is not possible to use the relations provided for H columns. As a result, there are relationships for determining the strength of panel zone in cruciform columns in an elastic and non-elastic state, provided that the rotation of the coupling fence is not quadrupled above the elastic limit.
