Olson Steel collaborated with Plant Construction on the seismic retrofitting of an aging structure originally constructed in 1957. Olson Steel was responsible for providing all the structural seismic retrofit on 23 floors of the building. Some of the retrofit work included reinforcing flange plates and box plates of beams, beam web doubler plates, column box plates, and column splice reinforcing plates. Additionally, Olson Steel was responsible for the Gusset plates, continuity plates, stiffener plates, and (272) tube steel braces incorporated with Taylor Device, Inc. dampers. The seismic retrofit upgrade further fortified the building’s capacity to withstand seismic forces. This comprehensive approach not only bolstered the building’s earthquake resistance but also exemplified Olson Steel’s commitment to delivering exceptional seismic retrofit solutions.
