Abstract: This paper discusses optimization of the size of opening i.e. depth and width of opening of castellated steel beam containing sinusoidal openings. Optimization of opening of sinusoidal shape was performed using finite element method (FEM). The results of FEM analysis are verified by implementing laboratory testing of 150 mm height castellated beam specimen. All the castellated beam specimens were modified from 100 mm I beam. Optimum results from FEM analysis was a castellated beam with sinusoidal openings having opening size 0.62 times its overall depth with S/D0 ratio 1.4 and D/D0 1.61 From laboratory testing results and FEM analysis it is observed that, the deflection obtained from FEM result is 1.170 mm. While deflection from experiment results is 1.172 mm. Percentage variation in above case is almost negligible, that is 0.18 percent.
