MULTI-CRITERIA APPROACH FOR THE EVALUATION OF SEISMIC DAMAGE TO CLADDING PANELS IN SINGLE-STOREY STEEL BUILDINGS

The present study investigates the damage evolution of cladding panels for increasing levels of seismic actions, exploiting a multi-criteria approach for local damage quantification in non-structural elements. The proposed methodology is presented and applied to a case study consisting in a single-storey steel building made of moment-resisting portals in the transverse direction and concentrically-braced frames in the longitudinal direction. Modelling aspects and a brief summary of the results are discussed. Specific attention is given to the investigation of the influence of cladding panels with non-symmetric distributions in plan.
