Concrete structures used for defence applications have to be able to resist sever dynamic loading caused by bomb blasts in their vicinity. Whilst concrete components are well placed to resist blast pressure waves, they can suffer high levels of damage due to fragment impacts. It is therefore important to include this loading in their analysis to ensure the final design will provide adequate protection to people and equipment.In this advanced scenario phase of the project the modelling techniques were required to be developed to include the simulation of loading from real ordinances instead of the idealised charges used in the basic scenario.
