Improving a 60s fire station without displacing firefighters.
Seismic strengthening for Station 63. South King Fire & Rescue need to improve the seismic performance of Fire Station 63 to keep firefighters safe. Reid Middleton performed seismic evaluation based on ASCE 31-03, then provided the structural design of a seismic retrofit for a two-story, three apparatus bay fire station that was constructed in 1964. The station is constructed with masonry walls and wood framed floors and roof. The seismic upgrade included adding new shear walls and strengthening floor and roof diaphragms. The station remained occupied during construction and structural improvements were designed to minimize the disruption to the building occupants.
