Comparison between a Traditionally Retrofitted Industrial Building and an Alternative Solution Using BRBs
Seismic retrofit of industrial buildings usually consists of traditional strengthening methods such as the addition or replacement of braces and welding of plates. This implies that the seismic force is maintained, or in some cases, increased due to stiffening. Consequently, a large amount of steel is needed to satisfy the code requirements. However, the use of buckling restrained braces (BRBs) as an alternative to the traditional retrofit increases the dissipation of energy and, as a result, a reduction of the seismic force is expected. This may produce in some cases a reduction of the steel required to obtain an appropriate performance of the building. In addition, the use of BRBs concentrates the dissipation in specific locations, then the behavior of the building is more predictable. In this research, an actual traditionally retrofitted industrial building is analyzed, and a quantification of the benefits of using BRBs instead of traditional methods is made. The comparison between both solutions is based on costs and seismic performance.
