| Popis: | Significant damage to architectural non-structural components caused by recent seismic events highlighted their importance in the building design and showed that their damage or collapse might have severe consequences. Therefore, the study of the seismic behaviour of non-structural components is very important to minimize the risk. In this context, a specific research project aimed to improve and expand the knowledge of seismic response of architectural non-structural lightweight steel drywall components started at the University of Naples “Federico II”. This paper presents the results of dynamic shake table tests performed on prototypes made of indoor partition walls, outdoor facade walls and suspended continuous ceilings. The influence on seismic response of prototypes from 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 performance in terms of damage occurrence was also evaluated by fragility curves, which showed a better seismic response of enhanced solutions than basic solutions and a seismic “fragility” of indoor partition walls higher than that of outdoor facade walls. Finally, a repair cost estimation was performed by highlighting that the repair cost of partitions is higher than that of facades. |
