Impact of shock waves from HE-detonation on reinforced concrete structures – Numerical and field studies
- An effective protection of structures against impact from detonation of high explosives (HE) necessitate certain design specifications to be met. In the event of an explosion, accidental or intentional, any damage in its neighborhood (especially, for example, to the structures of strategic importance) should remain as low as possible. The behavior of a structure under the shock loading from an explosion will determine the extent of the damage. The investigation of the relevant phenomena that occur during the event of an explosion is the objective of this study. In accordance with the test parameters, numerical simulations were performed and results were compared with those from field tests. The deformation of the wall under shock impact was simulated by implementing the appropriate interaction of fluid and structure. Moreover, the numerical pressure-time histories in front of the wall were compared with the ones measured in the field by means of piezoelectric pressure gauges,An effective protection of structures against impact from detonation of high explosives (HE) necessitate certain design specifications to be met.
