Seismic Upgrading - Retrofitting of Foundations

Steel water tanks, Contra Costa County, California, USA

During a seismic event, tank content will move from side to side, inducing dynamic uplifts on the tank foundations. To prevent damage at the foundation, high strength Ø25 mm and 32 mm DCP DYWIDAG Bars (THREADBAR ®) were used as tie down ground anchors around the steel tank perimeter.
