In this paper, the flexural behavior of RC member recycled heavy weight waste glass as fine aggregate was evaluated by finite element analysis. From the results, the analytical results do not reflect the experimental results. This is because the stress-strain curve of the concrete specimen obtained from the compression test was used as the input data for the ABAQUS. Therefore, the ABAQUS, based on the experimental results of the stress-strain relationship of concrete, predicted the load-displacement relationship without considering the reduction in load capacity.
