I Section ISMB150, Sinusoidal Castellated beam, IS code.
The castellated beam manufactured from its parent solid I beam by cutting it in zigzag pattern and again joining it by welding, therefore the depth of the beam increases. Hence, due to increase in depth of beam load carrying capacity of the parent I section is increased with same quantity of material. The increase in depth of castellated beam leads to web post buckling and lateral torsional buckling failure. In this study the IS 800:2007 is used for the designing of castellated beam by using parent section ISMB150 with different openings with same length . The Experimental investigation on castellated beam is done with different opening under two point loading. The comparative study is done for the sections this castellated beam are tested for two point loading under universal testing machine. The deflection at Centre of beam and various failure patterns are studied. Castellated beams with Sinusoidal web opening, 1/8th Sinusoidal web opening offer more load carrying capacity. The openings considered in the experimental study are standard Sinusoidal shapes like Sinusoidal web opening angle of opening with filleted radius 1/4th ,1/6th and 1/8th. Castellated beams are by and large furnished with Sinusoidal l openings in the web portion. In any case, in structural applications, suitable size and shape of openings in web are constantly a significant issue of concern.
