Seismic excitations are one of the most hazardous loading encounters during structure's lifetime. It has been observed that increased strength and stable energy dissipation capability are the most desirable mechanical characteristics needed to maintain structural displacements within tolerable levels. Moment resisting frames are widely used as lateral resisting systems when sufficient ductility and deformability are to be met. Generally three types of moment resisting frames are designed in practice namely Special, Intermediate and Ordinary, each has certain level of ductility and deformability. One of the most significant components of these structures dominating their overall behavior is connection for which careful design should be carried out in order to avoid immature connection failure and fracture. Comparative study on seismic responses of these three different types of structures is performed in this study. Fairly accurate model of connections are developed analytically including panel zone and beam to column joint model. Incremental Dynamic Analysis (IDA) is then utilized to not only assess the structural behavior and differences in response of the frames, but also to generate needed data for performance based evaluations of them. Results indicate that deformability and ductility of SMF could be explicitly exhibited in overall IDAs proving more efficiency of such structures to dissipate earthquake-induced excitations.
