Nonlinear dynamic analysis of profiled steel-concrete composite panels under blast-induced excitations

Abstract

The non-linear dynamic behavior of profiled steel-reinforced concrete (RC) composite panels which was subjected to blast induced excitations was discussed. The parametric studies were performed to evaluate the strength and deformation characteristics of composite slabs using finite element method. It was observed that the non-linear trend was exhibited in terms of maximum deflection, concrete strain and crack distribution with respect to reinforcement ratio. It was found that the effectiveness of using thicker panels depended upon the reinforcement ratio in restricting the severity of damage.
