Energy dissipation is a parameter that contributes to the deformation process of structural elements. Factors affecting the value of energy dissipation include concrete compressive strength, reinforcement ratio, cross-sectional dimensions, and history of loading that occurs on the structure. In this study, the graded concrete (GC) beams with a maximum reinforcement design was tested under flexural test to analyse the resulting energy dissipation. The resulting data was then compared to the reference beams. The results showed that: 1) The use of cross-sectional dimension ratio of 1/2 in GC beams using maximum reinforcement can increase the energy dissipation by more than 2000%; 2) Design of reinforcement area should be based on the higher concrete strength to increase energy dissipation up to 100%; 3) The use of GC save on construction costs can increase energy dissipation by up to 400% with a reduction in load capacity of 25%; 4) The use of GC to improve the properties of structural elements can increase energy dissipation by more than 60% while increasing load performance by almost 50%. © Published under licence by IOP Publishing Ltd.
