Full scale numerical analysis of high performance concrete columns designed to withstand severe blast impact
Publication: Research - peer-review › Article in proceedings – Annual report year: 2007
Polymer reinforced Compact Reinforced Composite, PCRC, is a Fiber reinforced Densified Small Particle system, FDSP, combined with a high strength longitudinal flexural rebar arrangement laced together with polymer lacing to avoid shock initiated disintegration of the structural element under blast load. Scaled experimental and numerical results of PCRC columns (200x200x1600mm) subjected to close-in detonation are presented in this paper. Based on these results and the use of geometrical scaling lows, a full scale column (800x800x6400mm) is designed and verified numerically to withstand 486.5 kg of PETN (85/15) High Explosives at stand off 1600 mm. Additionally, a LS-DYNA material model suitable for predicting the response of Polymer reinforced Compact Reinforced Concrete improved for close-in detonation and a description of the LS-DYNA multi-material Eulerian method for modeling the blast event is also presented in this paper.
