Abstract:

Now a day’s use of castellated beam is become very popular due to its advantageous structural applications. Fabrication of Castellated beam are done by cutting in its web of hot rolled steel (HRS) I section into zigzag pattern & after that the cutting portion are rejoining it over another. By rejoining the cutting portion over one another the depth of the beam is also increases. The openings provided in the web portion is generally circular, hexagonal, diamond or sinusoidal in shape. The load carrying capacity of the castellated beam is increased by increasing the depth of the beam. There are no of modes of failures in the castellated beam due to its increase in depth like lateral torsional buckling, formation of vierendeel mechanism, rupture of welded joint in a web post & shear buckling of web post which needs to take care of. Therefore for minimizing these failures modes study is carried out which shows that use of stiffeners in web portion is important. The literature survey shows that the use of stiffeners in the web portion of castellated beam minimizing the deflection in that portion & also increasing the strength. Review papers are suggested that using stiffeners along the transvers direction reduces the stress concentration near openings.
