“…A constant viscous damping ratio 0 ζ is assumed for all modes of vibration. Following Pipitone et al [2], the DSF is modelled as a set of N independent panels connected to the main structure by elastic springs at the floor level. The generic panel is modelled as a system composed by j lumped masses equally spaced by /2 h .…”

“…DSFs are becoming increasingly popular for their capability of improving the energy performance and the aesthetics of buildings. Recently, the application of DSFs as vibration absorbers has been investigated assuming either deterministic [1] or stochastic excitation [2]. Previous studies mainly focused on the optimal design of the DSF by varying the layout of panels and design parameters such as the stiffness of links to the building.…”

“…The present study addresses the stochastic analysis of a shear-type frame equipped with a DSF subjected to ground motion acceleration taking into account epistemic uncertainties affecting the excitation. Following Pipitone et al [2], the DSF is modelled as a set of independent panels, each one described as a mass lumped system connected to the main structure by elastic springs at the floor level. Within the strong motion phase, seismic excitation is modelled as a zero-mean stationary Gaussian process, fully characterized by an imprecise power spectral density (IPSD) function, recently proposed by Muscolino et al [3].…”

Abstract. Double-skin façades (DSFs), widely used in buildings to provide specific thermal efficiency, acoustic isolation, and weather resistance properties, have been recently used as passive control systems. The present study focuses on the stochastic analysis of a shear-type frame equipped with a DSF subjected to ground motion acceleration modelled as a zero-mean stationary Gaussian random process fully characterized by an imprecise power spectral density function i.e., with interval parameters. The influence of imprecision of the seismic excitation on the performance of the DSF is investigated by evaluating the bounds of the interval reliability function for a selected displacement process of the frame structure, in the framework of the classical first-passage problem.
