On the Discrete Numerical Simulation of Steel Fibre Reinforced Concrete (SFRC)

摘要

The main aim of this article is to simulate the tensile behaviour of steel fibre reinforced concrete (SFRC) by using the finite element analysis (FEA) code, ABAQUS. A simple, direct, discrete modelling plan is proposed based on pioneering theoretical work by others. A bilinear stiffness degradation model for steel fibre was considered to simulate the softening portion of the load - crack mouth opening displacement curve. A corresponding sensitivity study was conducted and recommended values for all relative parameters were established. Overall, the simulated results projected the main features of the tensile behaviour of steel fibre reinforced concrete (SFRC) beam specimen satisfactorily.
