Retrofit
ABOUT

 

Plaza 555 is in Sacramento and consists of two non-ductile 14-story reinforced concrete frame buildings originally constructed in the 1970s. The owner, Pac West Office Equities, hired Miyamoto International Structural and Earthquake Engineers to retrofit the buildings.

 

The engineers at Miyamoto used SP3-Design (now SP3-Advanced) to iteratively design their retrofit solution; they selected a Taylor viscous dampers as part of their retrofit and where able to reduce expected losses down to only 12% loss for a 10% in 50-year ground motion.
