Recent development in seismic resistant steel frames was directed to the development of an effective and efficient energy dissipater such as a link in eccentrically braced frames. This research was carried out to study the performance of the shear-type link due to cyclic load, especially to improve the energy dissipation as well as the ductility and the strength of the link itself. Experimental work has been carried out to two specimens of bolt-connected link. Additional side-extended plates were welded at top and bottom flanges of each end of the link to prevent early failure of the link. A cyclic load was applied under displacement control. The results show that the side-extended plate has significantly improved the performance of the link, both in the strength, ductility and energy dissipation.
