The use of castellated beams in many types of constructions is quickly gaining popularity. This is a result of the section's enhanced depth without adding weight, excellent strength-to-weight ratio, low maintenance requirements, and low cost of painting. Increased vertical bending stiffness, ease of service provision, and appealing appearance are the main advantages of castellated beams. Castellated beams are made by zigzagging cutting I sections, then re-joining them to increase the depth of the parent I sections. When castellated beams are loaded, their increased depth makes them more susceptible to web post buckling and lateral torsional buckling failure. There are numerous other forms of failure that must be considered, such as the development of flexure mechanisms, lateral torsional buckling, and vierendeel mechanisms, rupture of the welded joint in a web post, and shear buckling of a web post. A study demonstrates how using stiffeners in the beam's web part can reduce these failures. As a result, a thorough analysis of the stiffeners' quantity, size, and readily available positions in the castellated beam's web part is required. In order to explore the experimental and analytical behaviour of the castellated beam with stiffeners, an attempt has been undertaken in the current paper.The result indicates that use of end stiffeners at end portion of castellated beams helps in increasing the strength and also minimizing the deflection.
