Abstract

RC beams are important structural components that are becoming vulnerable to extreme dynamic loads like impact and blast events whereby they experience complex nonlinear responses where strain rates are high, energy transfer is rapid and localized damage. It is vital to understand how they behave under these conditions in order to achieve structural safety and resilience. The Finite Element Modelling (FEM) has proved to be a strong computational model that can effectively model material nonlinearity, stress wave propagation, cracking and failure mechanisms that cannot be effectively modeled by experimental techniques. This paper is a review of FEM methods used in the study of RC beam under impact and blast loading, with the main issues addressed in the paper being modelling methods, constitutive models of materials, methods of loading, and failure, and validation strategies. It also looks at recent developments, such as hybrid modelling methods, incorporation of high-performance materials, and also explains the current problems, such as the computational complexity and uncertainty in the parameter. The purpose of the review is to offer a synthesized view of the existing practices, and to determine the future research directions towards improving the face validity and efficacy of numerical simulations in structural engineering.
