Everett High School Cafeteria Building & Commercial Building Seismic Rehabilitation
Everett School District, Everett, WA
A partial seismic rehabilitation of the Cafeteria and Commercial buildings at Everett High School was performed by Reid Middleton to meet the Life Safety performance objectives using ASCE 41 Seismic Rehabilitation of Existing Buildings qualifications for building elements receiving upgrades. The project built on seismic assessment work previously done by the school district and addressed deficiencies identified during that work. The 2-story cafeteria building, constructed in 1939, consists of a steel trussed roof, wood diaphragms and concrete and masonry bearing walls, with wood framed additions on each end of the building. Rehabilitation included strengthening existing connections between walls and diaphragms, and beams and columns. The 3-story Commercial Building, constructed in 1915 and modernized in 1990, consists of concrete pan joists spanning the interior and exterior concrete bearing walls. Rehabilitation included the addition of steel drag members and concrete shear walls at each end of the building and near the elevator core.
