Cyclic behavior of the in directed I beam to the box column connection with cover plates

Box columns are frequently employed as a part of special moment resisting frames in region of highseismic risk such as most Asian countries and Iran. One of the approaches to improve the connectionwith the box column is to strengthen the joint. So a new method is proposed to modify the momentconnection of Steel I beam to box column by using cover plates. In this new method, the beam sectionnever touches the column face. Separation between beam section and column eliminates brittlebehavior and all other uncertainties that are intrinsic with the use of complete penetration groove weld.In order to investigate the behavior of in directed I beam to the box column with new geometry in theseismic zone areas, two full scale tests were conducted, subjected to cyclic loading. The results indicatethat the proposed connec
