Abstract

The sudden collapse of historic ceilings represents one of the major public safety issues threatening the heritage sector globally. The pressing need of fast, efficient and rigorous approaches to assess the health status of historic ceilings motivated the research presented in this paper. A stochastic approach is proposed as a tool to map the displacement response peak fractile at various locations of the ceiling, thus identifying any local anomalous deformation indicating critical areas within the ceiling. Extensive parametric studies on a FE model of a traditional plaster ceiling are undertaken to explore the potentiality of such approach.
