Abstract: Panel zone is a region of the column which is bounded by the column flanges and continuity plates and plays a vital role in determining stiffness and capacity of the frame. Despite the extensive researches conducted on the panel zone behavior, there are different viewpoints on how panel zones function. Since box columns are used widely in the moment-resisting frames, presentation of a mathematical model for the panel zone behavior for these columns seems essential. This study attempts to present some relations in order to determine the shear capacity, the linear stiffness and non-linear stiffness of the panel zones in the box columns. For this purpose, a comprehensive parametric study is conducted, using the ABAQUS software; accordingly, a mathematical model is introduced. Then, the results of the mathematical model are compared with the results of other sources, and the accuracy of the obtained results of the model is proved.
