2850 Telegraph Seismic Strengthening

The voluntary seismic retrofit of this six-story concrete structure presented a number of challenges to Tipping Mar + associates. The medical office building, which was located on a near-fault site, had to meet the University of California-Berkeley's stringent seismic safety codes. In addition, the solution had to preserve the building's office space on a limited budget. The solution was an ingenious combination of two more common seismic design techniques, which was the use of reinforced concrete wall construction combined with the self-centering capability of un-bonded vertical post-tensioning. High-strength cables run through the cast-in-place concrete wall to minimize permanent residual deformation after earthquake disruptions.This approach adhered to both the architectural and the economic demands of the design mandate. The solution reduced the intrusion of structural elements in the building's usable space while utilizing traditional methods of cost-effective concrete construction.Architect: GLP
