Behavior Factor and Main Period of Steel Moment Resisting Frames with Semi-Rigid Connection

In this paper, the effects of connection stiffness on main period of vibration and behavior factor of moment resisting steel frames with semi-rigid connections are evaluated. For this purpose, behavior of different moment resisting steel frames with semi-rigid connections with 1, 2, and 3 spans, and 1, 2, 4, 6 and 8 stories and with different connection stiff nesses are considered. Based on the results, new relationships for the main period and behavior factor of moment resisting still frames with semi rigid connections are purposed.
