Analysis, testing, design and construction of a base isolated/supplementally damped building

The first actual application to a demonstrative strategic building of a special base isolation/supplemental damping system, where fluid viscous spring-dampers are coupled to steel-Teflon sliders, is presented in this paper. The results of a testing campaign aimed at assessing the interference of the dissipative actions of the two component devices, as a final step of the research studies previously developed by the authors on this technology, are summed up. The design and performance evaluation analyses carried out on the building are then discussed. Highlights of the construction works and technical installation details are finally illustrated.
