Abstract

Damage criteria based on support rotation or midspan deflection are suggested in the protective technology manuals (like UFC 3-340-02 2008) and these criteria to define damage levels are based mainly on the performance of specially designed and detailed elements. The behaviour and performance of concrete elements designed without explosive loading consideration sometimes become significant when exposed to blast loading. This paper investigates the performance of concrete elements designed for standard loading situations but placed under blast loading. Theoretical investigation of flexural capacities of Normal strength, High strength and Reactive powder concrete elements which are not specially designed for blast loading has been studied. Nonlinear dynamic FE element analysis was performed using commercial software DIANA to compare results obtained from theoretical analysis and to present the effect of the reinforcement ratio, strain rate and concrete failure criteria on damage assessment of various types of concrete.
