Eccentrically braced frames are widely used as lateral-force resisting system for multi-storey buildings located in seismic areas. Capacity design principles used in modern seismic design codes are deemed to constrain plastic deformations to dissipative elements only, which in eccentrically braced frames are represented by links. The aim of using these frames is to reduce the repair costs and downtime of a structure hit by an earthquake. This objective is to be attained through removable dissipative members (bolted links) and re-centering capability of the structure. Numerical studies are performed in order to investigate the practical feasibility of the replacement procedure; analyzing dual frames obtained by combining steel eccentrically braced frames with removable bolted links with moment resisting frames. Practical solutions regarding order in which bolted links need to be replaced are proposed, as well as the mounting of some temporary tie braces, for safety measures during the link removal procedure.
