Seismic behaviour of non structural systems in CFS: characterization of seismic response through shake-table tests

The seismic damage of non-structural components could involve functionality interruption of the most affected buildings and substantial economic losses. Therefore, a cooperation be-tween the University of Naples "Federico II" and KnaufGips KG Company, aimed to the knowledge of seismic response of lightweight steel drywall nonstructural components was car-ried forward. The paper presents the dynamic tests on shaking table of protoypes composed by interior partition walls, exterior façade walls and suspended continuous ceilings. The influ-ence on seismic response of basic and enhanced anti-seismic solutions, corresponding to the use of fixed or sliding connections at the walls and ceilings perimeter, was investigated. The seismic response in terms of damage occurrence was also evaluated by fragility curves, which show that enhanced solutions have a better seismic response than basic solutions and interior partition walls have a higher seismic “fragility” than exterior façade walls.
