Numerical Analysis and Validation with Experimental Method of Castellated Steel Beams with Hexagonal Web Opening
Keywords:Castellated beams, Hexagonal web, Web opening, Numerical analysis
Steel structure are employed in heavy industrial building to provide good strength and also carry tonnes of loads safely. The castellated beams are fabricated by cutting the I section in its web by zigzag pattern and re-joining the two halves by proper welding process, the depth of the section will be increase. The purpose on this study is to validate the finite element analysis result with the experimental method  in in the form of deflection and stress or ultimate strength of the CSB also investigate the effect of hexagonal holes parameter in the performance of beams. The total length and ratio of the expansion of the beam are same and only depth of the hexagonal holes are changed. All the parameter of the CSB is taken same as experimental method and compare the behaviour of beams of each group under the similar boundary condition. In order to reach the most optimum design of beam, several models in the form of different profile castellated were tested on the basis of ultimate strength and the most optimum design was selected. Based on the satisfaction of different factors in the form of load bearing capacity, stress induced and deflection the optimum selection of beam was performed. The result obtained by ANSYS software is compared with the experimental result  to validate the result of I Beams. In these two different approaches the boundary condition for analysis is same and other parameter is also kept at constant.
