| Résumé : |
In this work, simplified models for the dynamic analysis of traditional reinforced concrete (RC) and fibre-reinforced concrete (FRC) circular plates under blast loads are proposed. The cases of plates simply supported or resting on Winkler-type soil are studied. The two cases under study intend to provide a simplified tool for predicting the response respectively for specimens subjected to blast pressure wave inside shock-tube facilities and for slabs on ground under blast loads. The second case also represents the loading conditions inside a new shock-tube facility specifically intended for the investigation of underground tunnel lining subjected to blast loads. The aim of this work is the pressure--impulse diagrams derivations for circular plates with several material characteristics, radius/thickness ratio and Winkler’s constant. |
