Investigation of the Effect of Uncertainty of the Ibara-Madina-krawinkler Model Parameters on Seismic Collapse Capacity in Steel Moment Resisting Frames

Although the total collapse of buildings under earthquake occurs less but the incidence in recent decades and the possibility of its re-occurrence in the future has made research inevitable in this field. Several numerical and laboratory studies have been carried out on the seismic collapse of the s...
