Analysis of Reinforced Concrete Beams Subjected to Impact Loading

Abstract

The utilisation of complex nonlinear material models for concrete in numerical simulations is necessary for the accurate representation of structural behaviour. However, the successful modelling of such complex behaviour depends on a good understanding of the material model parameters. This paper deals with the critical issue of material parameter sensitivity in the context of RC beams subjected to impact loading. The objective was to establish relationships between the material parameters and the responses, including deformations and stresses, using sensitivity. This is the main key to understanding the complex interaction of these parameters and their influence on the structure.
