Vulnérabilité de structures soumises à des explosions et impacts : Projet ANR PGCU 2007 "VULCAIN"

Abstract : The project ANR PGCU VULCAIN (2008 - 2012) studies the structural safety of industrial cylindrical structures (stock, protection, containment) that might be impacted by various projectiles or submitted to an explosion. This work underlies in a partnership between well-known and complementary institutes and firms and universities. This study aims both (i) at improving the quality and the efficiency of physical impact and blast loading models used for refined models (of sensitive structures), reducing of the computational size of refined models of structures under impact and (ii) at providing complementary studies and recommendations for engineering practices for common industrial vessels. The Domino effect is of concern, as industrial facilities submitted to explosions can become projectiles sources that might cause damage or another explosion. In case of accidental blast on current atmospheric storage tanks in oil and chemical facilities, results show that the current usual French practice for SEVESO facilities can lead to conservative or dangerous assessments, since it ignores projectile and assumes a maximum overpressure value observed from accidental data. The formalisation of the Domino effect is being studied, writing the probability of a tank, taking into account different failure modes and the order of occurrence of these modes The final aim of VULCAIN is to contribute to improve diagnosis, prevention or protection actions. Therefore, ongoing work is to summarize and popularize last results.
