Modelling hybrid reactive powder concrete T-beams

Abstract

Abstract The purpose of current study is to evolve a nonlinear finite element model to simulate the influence of the type of concrete on reactive powder concrete (RPC) T-beams. Four simply supported T-beams were modelled and the difference is in the type of concrete (full normal strength concrete (NSC), full RPC, RPC in the web only, RPC in flange only). Commercial ABAQUS software package with the damaged plasticity model (CDP) is proposed for modelling the reinforced concrete (RC) structural members. The compressive stress-strain relationship and uniaxial tensile in addition to the damage parameter of the material were proposed to be effectively utilized in ABAQUS. From the analysis of the finite element model for each beam, the predicted ultimate load capacity against the deformation response was gained and validated with the results of the experimental work.
