Experimentation on Twist Carrying Capacity of Castellated Beam

Castellated beams are those beams which has openings in its web portion. Castellated beams are fabricated by cutting the web of hot rolled steel I section into zigzag pattern and thereafter re-joining it over one another. Use of castellated beams is become popular now days due to its advantageous structural applications. Steel is the material of choice for design because it is inherently ductile and flexible. ASTM stands for American Society for Testing and Materials over 12,000 ASTM standards operate globally. They improve the lives of millions every day combined with our innovative business services, ASTM standards enhance performance and help everyone have confidence in the things they buy and use. ASTM standards use to find out torsional moment capacity carried by given beam after castellation. The study of performance is based on angle of twist, torsional moment carrying capacity of castellated beam sections like diamond, rectangular opening. From experimental results, it is concluded that torsional moment carrying capacity of diamond opening is more as compared to rectangular opening.
