Abstract
The use of functionally graded concrete in structural member provides a beneficial prospect since it promises the increase of beam stiffness with less of construction cost. In structural analysis, concrete stiffness plays role in determining the performance of beam elements in resisting deflection due to the working loads. In this study, the behaviour of the graded concrete beam is continuedly investigated. The bending moment-curvature relationship of the graded concrete beam is conducted numerically to understand the level of ductility and the failure mode compared with the conventional beam. A singly reinforced graded concrete beam is modelled using a non-linear simulation program, Strand7. The result of the analysis is then evaluated in accordance with the Eurocode. The graded concrete beam is expected to exhibit a reliable behaviour of bending moment – curvature so that the graded concrete beam is possible for advanced application as structural elements.
