Abstract: One way to reinforce steel structures is to use braces which are both concentric and eccentric. Concentric braces have high stiffness and low ductility while eccentric braces have initial stiffness and proportional ductility. In eccentric braces, link beam is an area under plastic deformation which leads to earthquake energy absorption. These beams are either horizontal as a part of story beam or vertical located between story beam and two braces. Link beam length is one of the most important parameters in analysis and design of these structures. Behavior of link beam will be closer to shear link when its length is lower. If length of a link beam exceeds a certain amount, its behavior will shift to shear link. This study tends to evaluate seismic performance of frames with vertical link beam by using DRAIN-2DX which is the most powerful software for non-linear static and dynamic analyses.
