This paper presents results of a capstone senior project at California State Polytechnic University, Pomona. Students conducted a vulnerability assessment of a five-story building constructed in Southern California. The structure has non-ductile concrete shear walls at the core and gravity frames at the perimeter. Partial infilled walls exist within the perimeter frames, creating captive columns. Students studied as-built plans for the structure and conducted an assessment of the building based on FEMA-310. They modeled the structure in ETABS and performed an analysis under combined gravity and lateral loads. The students identified the most vulnerable structural elements in the building. They proposed a retrofit scheme to mitigate the risk of collapse due to seismic loading, which includes adding supplemental reinforced concrete shear walls to reduce torsion, shotcreting to increase wall shear capacities, saw-cutting infill walls, and fiber wrapping to increase the shear capacity of vulnerable perimeter columns.
