One suitable seismic retrofit solution is the installation of steel braces to increase the strength and ductility of a building. In this study, the braces were connected to gussets furnished with anchor brackets, which were fixed by means of a few postinstalled concrete anchors. The clear structural system and the increased utilization of the anchors allowed the anchorage to be designed precisely and economically. The use of buckling-restrained braces (BRB) improves the energy dissipation efficiency and allows the limitation of the brace force to be taken up by the highly stressed anchorage. Cyclic loading tests were conducted to investigate the seismic performance of BRBs connected with post-installed anchors used to retrofit reinforced concrete frames. The tests showed that the proposed design method is feasible and increases strength as well as ductility to an adequate seismic performance level.
