Although connections of steel structure have been idealized as fully rigid joints or hinge joints for convenience in structural analysis and design process, many connections show the behavior of semi-rigid connections. The semi-rigid connections enable the construction process easy and make it possible to utilize the strength and stiffness of members. The large energy absorption
capacity of the connections due to their inelastic behavior makes it possible to design member with good earthquake-resistant capacity. In this research, three-parameter model is evaluated as a simplified analytical model to describe the hysteretic behavior of connections of steel structure by utilizing the experimental results of partially restrained composite connections as well as
composite beam. Three-parameter model which can simulate stiffness degradation, strength deterioration and pinching was successful to describe the hysteretic behavior of partially restrained composite connections as well as composite beam.
