摘要

This paper presents an analytical study aimed at evaluating the feasibility of using buckling-restrained braces as a retrofit scheme in existing multi-bay multi-story steel buildings. For that purpose, the seismic response of four two-dimensional frame models representative of typical steel buildings designed in regions of high seismicity was analyzed prior and after including buckling-restrained braces as a retrofit strategy. The braces were designed following force-based and displacement-based approaches. Each frame was subjected to a set of earthquake ground motions recorded on accelerographic stations placed on firm soil sites. It was observed that buckling-restrained braces allow for an efficient reduction of the peak drift demands in the retrofitted frames. However, since the beneficial effect of the braces cannot be fully controlled under a force-based design approach, it is concluded that a displacement-based design approach is the best option to achieve adequate drift control for the different performance levels.
