One of them existed in the connection of column to base plate. The appropriate understanding of structural connections behavior and the awareness of how transmission of power occurred by their connections and more accurate understanding of their behavior is essential for modeling and structural analysis. In the following study, at first, the connection of the column to base palte was studied under the monotonic loading in laboratory. Then, the finite element method and criteria are used for designing the moment-rotation curve. The results of the study indicated that the moment-rotation curve of in experimental sample and the analytical methods are reasonably close to each other. Therefore, the finite element methods and criteria can be used with reasonable accuracy in the behavior evaluation of this type of connection. Keywords: column to base plate connection, moment-rotation curve, rigidity.
