The Stockton, originally a 252-room hotel built in 1910 and listed on the National Register of Historic Places, lay vacant for 20 years due to cost-prohibitive and function-prohibitive rehabilitation designs by other engineers. Miyamoto’s High-Performance Earthquake Engineering approach made this adaptive re-use project viable, preserving the integrity of the historic structure, while providing new office and retail spaces along with affordable senior housing units.
The seismic technology employed by Miyamoto provided more than a 20% reduction in story drift, protecting existing brittle materials and reducing member stresses to nearly elastic levels. Building performance was upgraded from potential collapse to near immediate occupancy after a major seismic event. Miyamoto performed nonlinear dynamic analyses and designed seismic shock dampers and fiber reinforced polymer composites at the first story level to reduce seismic demand, producing a very economical rehabilitation cost of $9/SF. The innovative rehabilitation of this city’s iconic hotel won many awards.
