The use of cold formed steel structures is increasing throughout the world as they are efficient in terms of stiffness and strength. The main aim of introducing the concept of cold formed thin section is to reduce the cost to strength ratio of the building components and to reduce the overall cost of construction besides making the structure light in weight. Castellated beams are becoming very popular now a day due to its advantageous structural applications. The advantage of using such beams is that it causes reduction in total weight of the structure and hence requires less quantity of steel .Investigation of cold formed I section castellated beam with hexagonal openings is carried out by varying the size of openings and the spacing between openings. The performance is analyzed using ABAQUS 6.13 by keeping the depth and width of the sections constant. Theoretical investigation is carried out by using North American specification for the design for cold formed steel AISI S-700:2007, Australian/New Zealand design code for cold formed steel AS/NZS 4600:2005. The results predicted using numerical analysis and theoretical analysis are compared and presented.
