摘要

The verification of flexure behaviour testing of concrete is a costly process, which pushes the researchers and scientists to use simulation methods or tools for simulation. The experimental and Finite Element Method (FEM) is explored using ABAQUS, the flexural behaviour of a reinforced self-compacting concrete (SCC) beam of 150 mm x 200 mm section and 2000 mm length was casted with copper slag (CS) as replacement of 0, 20, 40, 50, and 70% as fine aggregate to study ultimate load capacity, ductility, stiffness, and fracture properties. The concrete damaged plasticity (CDP) model was chosen as a homogenized model to adopt the crushing. The beam was represented using C3D8R solid elements, as well as truss elements T3D2 were used to represent steel reinforcement, which was embedded in the concrete to guarantee the presence of perfect bonding. The predicted responses were in good conformity with test load-deflection behaviour and flexural capacity, as the robustness of the developed simulation approach was proven to be effective in the test of the structural performance of the sustainable SCC beam.The ABAQUS model accurately predicted the beam behavior, with average errors of 4.91% in ultimate load and 6.21% in peak deflection. The best agreement was obtained for the CS40% beam, with errors of only 2.22% and 1.96% in ultimate load and peak deflection, respectively, confirming the accuracy of the finite element model. The validated FEM approach provides additional insight into the structural behavior and performance of SCC beams incorporating copper slag, complementing the experimental investigation and supporting future structural analysis and design.
