Finite Element Modelling of Laboratory Tests on Reinforced Concrete Beams Containing Recycled Aggregate Concrete

The predictive accuracy of the finite element (FE) based packages are broadly on compatibility adopted non-linear numerical procedures and incorporated material models. However, routine way to define concrete is not applicable concretes containing substitute materials in place conventional ingredients. Therefore, this work, appropriate definition terms stress-strain relations have been utilized simulate experimental work RC beams coarser fractions recycled aggregates (RCA). entire has carried out into two phases; an simulation using FEA package, ABAQUS. In part, three number full-scaled beam specimens were tested failure through four-point monotonous loading. replacement level natural coarse was taken as 0.0, 50 100% by direct substitution. phase, addition laboratory evaluated properties like compressive stress, tensile stress elastic modulus, measured relationship for reinforcing steel constitutive aggregate (RAC) reported literature considered input. relationships RAC selected from treated user defined model. Besides strength, serviceability deflections, crack patterns load deformation characteristics simulated investigated compared with those specimens.
