CSULB Liberal Arts Buildings 2, 3, and 4 were some of the last buildings within the 23 campus CSU System still on the Seismic Priority 1 List indicating seismic vulnerability. The three, two-story classroom buildings were originally constructed in the 1950’s with concrete one-way pan joist roof and floor structures, perimeter concrete columns, and concrete and masonry shear walls as the lateral force-resisting system. The buildings are founded on conventional spread and continuous footings. The project scope included full architectural and MEP upgrades to the buildings, the addition of air conditioning, ADA upgrades to ramps, walkways and balconies, and renovation of outdoor spaces between buildings. Strengthening consisted of added shear walls and concrete in-fills to address short, captive column conditions, and Carbon Fiber Reinforced Plastic (CFRP) to support added rooftop mechanic units.
