Evaluation of the seismic capacity and demand of nonstructural components

The research activities on n onstructural components conducted in the past few years at the Department of Structural Engineering, University of Naples Federico II are described in the paper. The research is focused on the seismic qualification of plasterboard ceiling systems and plasterboard and brick internal partit ions through shake table tests. The test campaign on continuous ceiling systems highlights the low fragi lity of the tested specimen, primarily caused by: (a) the continuous nature of the ceiling, (b) the dense suspension grid, and (c) the large number of hangers being used. Different tests show an excellent seismic performance of the plasterboard partition w all, characterised by innovative anti - seismic details subjected to interstorey drifts even larger than 1%. The dynamic tests performed at different intensity levels on hollow brick partitions, instead, highlight an extensive damage for moderate interstorey drift demand. Finally, a study on the seismic demand in acceleration - sensitive nonstructural components is conducted
