Abstract

Abstract Nowadays, Engineers are actively seeking to improve construction materials and properties. In that, the usage of the castellated beam is become very popular due to its advantageous structural applications Castellated beams are those beams which have openings in their web portion. Castellated beams are fabricated by cutting the web of hot rolled steel (HRS) I section into zigzag pattern and thereafter rejoining it over one another. Use of castellated beams is become very popular now a day due to its advantageous structural applications. This is due to increased depth of section without any additional weight, high strength to weight ratio, their lower maintenance and painting cost. The principal advantage of castellated beam is increase in vertical bending stiffness, ease of service provision and attractive appearance. However, one consequence of presence of web opening is the development of various local effects. In this research we have suggest the Indian Standard Code based methodology for designing of castellated beams. So, the first objective of this research is to investigate the performance of castellated beam designed by IS code method against which is designed by British Standard method. The study of performance is based on deflection, load carrying capacity of castellated beam. We compare the castellated beams design by IS Code method with conventional castellated beams design by British Standard based on their load carrying capacities. The opening is generally provided in web hexagonal, rectangular, diamond or square in shape. By studying the different research paper, it found at castellated beams with hexagonal, rectangular or square opening mostly fails due to shear concentration at the corner opening, the second objective of this research is to provide new web opening that is sinusoidal opening to avoid failure of castellated beam due to shear stress concentration at the corner of the opening. The study of this project is based on deflection, load carrying capacity of new sinusoidal opening shape castellated beam compare to castellated beam with hexagonal web opening.
