ABSTRACT
The main objective of the COST Action C26 is to increase the knowledge on the behaviour of constructions located in urban habitats and subjected to exceptional and catastrophic events. One of the key tasks to achieve this goal is to define suitable tools for predicting the ultimate response of such constructions under extreme conditions, occurring when both loading and structural resistance are combined in such a way to reduce the safety level below acceptable values (Mazzolani, 2008).
