Abstract
To increase the capacity of the WF profile, it can be modified by changing its geometry into a castellated beam. Castellated beams have several variations of opening shapes. In 2020, the author obtained the bending behavior of a hexagonal opening castellated beam, which resulted in optimum bending capacity at a hexagonal opening angle of 450. In this study, the difference in bending strength produced by the hexagonal opening castellated beam and modified opening shape will be investigated. ANSYS numeric testing was conducted to determine the behavior of the castellated beam. The test model used in this study was a modified opening castellated beam with several variations of shapes (M1 to M5). Based on the results of the ANSYS numeric testing, the optimum castellated beam from the modified opening shape was found to be a diagonal Warren-type opening (M2) with Pyield=110.8kN and Pultimate=170.5kN. The bending capacity of the modified opening shape castellated beam was then compared to the hexagonal opening castellated beam. The modified opening shape produced better results than the hexagonal opening shape. The hexagonal opening castellated beam had Pyield=61.7kN and Pultimate=95kN. The deformation experienced by the modified opening shape castellated beam was smaller than the hexagonal opening shape, indicating that the modified opening shape had a greater moment of inertia than the hexagonal opening shape.
