35. SEISMIC REHABILITATION OF A HISTORIC NON-DUCTILE SOFT STORY CONCRETE STRUCTURE USING FLUID VISCOUS DAMPERS

Hotel Woodland is one of the first structures in North America to be seismically retrofitted using viscous dampers. This four story 1927 vintage Historical Landmark reinforced concrete building is located in Woodland, California. It was essential to improve the earthquake response performance of the building and minimize cost while maintaining the historical appearance of the building. This paper presents the processes and decisions regarding retrofit criteria and design procedure for earthquake demand, building response performance, historical interests, and economic considerations.
