Analytical Assessment of Effects of Cover Plates on Improvement the Seismic Nonlinear Behavior of Moment Link to Column Connections in Eccentrically Braced Frames

Many codes and regulations for designing of steel structures the same as 10th part of Iranian national buildings code don’t offer any solution link-to-column connection in eccentric braced frames. In eccentrically braced frames (EBF), required ductility and a major part of absorption and energy depr...
