Modelling and Experimental Verification of Reinforced Concrete under Blast Load

Title:
Modelling and Experimental Verification of Reinforced Concrete under Blast Load

Type of project:
PhD.-project

Responsible part:
DTU, Dept. of Civil Engineering

Description:
Research in the field of blast loading on structures over the past fifty years has been mainly the privilege of various government and military establishments, as the perceived risk related to ammunition storage and handling, and to the threat focused on events stemming from the prevailing ‘cold-war’ military doctrine. Blast loading has also been studied in relation to risk of industrial explosion accidents. The more recent emergence of terrorist explosions of public buildings has prompted a steady increase in university-level research over the past 20 years. As such, civilian research within this field can still be considered relatively new. Evidence of this can be found in the fact that the First International Conference on Shock and Impact was held as late as 1989. Nevertheless, important advances in the understanding of blast mechanics and structural response have been made, although significantly more research is needed. Increases in computational power and advances in Finite Element (FE) modelling have led to the creation of sophisticated computer models that can simulate structural materials and members with a fair degree of accuracy. Therefore, one may assume that a mastery of such tools would lead to the accurate modelling of structural response to any given blast scenario. Unfortunately, this is not the case, as it has been shown through numerous recent studies that most mathematical models fall short in their predictions of actual structural response.
