Abstract

The aim of the study consists in evaluating the life-cycle costs of a r.c. 3D structure equipped with FPS bearings having different isolated periods. Assuming friction coefficient and seismic input intensity as random variables characterized by appropriate probability density functions, the Latin Hypercube Sampling method has been adopted as random sampling technique. Bivariate structural performance curves for each story of the superstructure and for the substructure as well as seismic reliability-based design abacuses for the isolation level have been defined for the different values of the isolation degree. Finally, the life-cycle cost analysis of the isolated system with different curvature radius of the FP bearings has been accomplished taking into account both the initial costs and the expected loss costs, due to future earthquakes, of the overall system during its design life (50 years).
