Concentric braces are used widely in steel structures, due to ease, low implementation cost and reconstruction speed. In the last two decades, these benefits have created prime research incentives to increase their ductility. The usage of dutiable elements is one of the methods to increase ductility. In this article, a steel ring is used as a dutiable element. The extent of energy absorption and ductility is studied both analytically and experimentally. A steel ring can be welded to two steel plates and can easily be installed within concentric braces. The loading capacity of the steel ring is a function of its length, radius, thickness and yield stress. This property can be used to design a suitable ring, compliant to brace capacity. Results obtained show a high level of energy absorption and a good ductility for the steel ring.
