The reinforced concrete beam structure plays a role in receiving bending force and shear force so that it will undergo deformation during loading. In order to maximize the performance of the beams, reinforcement is added to help in withstanding tensile stresses because the concrete is weak against tensile. If the deflection arising from large loading results in the servisability of the beam is also less comfortable. For this reason, the rigidity of the beam needs to be designed so that the deflection of the beam can be limited. Realizing the importance of rigidity to the behavior of structures, the researchers conducted research on the behavior and characteristics of graded concrete beam. This research was conducted to determine the effect of singly and doubly reinforcement configurations on the rigidity of graded concrete beam. There were six specimens in this study. Each specimen is formed with two concrete mixtures, namely 20 MPa and 40 MPa with a beam shear span ratio of 2.5. Testing was performed numerically using the FEA application. The results showed that the behavior of single-reinforced and double-reinforced graded beams was between their control beams. Then, the double reinforced configuration on the gradation beam results in higher rigidity than the single reinforced gradation beam with an increase of up to 27.51%. The deformation ability of double reinforced gradation beams has increased by up to 38% than that of single-reinforced gradation concrete beams. In addition, with a double reinforcement configuration, the curvature of the gradation concrete beam is reduced to -2.19%. The design of the double reinforcement configuration is more recommended as a reinforcement for gradation concrete beams in subsequent studies. [ABSTRACT FROM AUTHOR] |
