BLAST RESISTANCE OF REINFORCED PRECAST CONCRETE WALLS UNDER UNCERTAINTYFranco Bontempi
Extreme loads can have devastating effects on civilian structures since these buildings are not designed to have to withstand extreme events. Typical buildings and other critical infrastructure are particularly prone to external man-made attacks. This study focuses on probabilistic analyses, and investigates the probability of failure of a precast concrete wall subjected to blast loads. The wall under investigation is a non-load bearing precast concrete panel used as exterior cladding for buildings. From the blast design point of view, these walls must protect people and equipment from external detonations. The aim of the paper is to compute both the fragility curves of typical precast concrete cladding subjected to blast loads, and the failure probability of the cladding, considering a detonation of a vehicle borne improvised explosive device (VBIED). To this aim non-linear dynamic analyses are carried out by the widely adopted equivalent non-linear SDOF method for the precast concrete panel. The fragility curves and the failure probability of the precast concrete cladding wall are computed using Monte Carlo simulations.
