Now a day, use of castellated steel beams has become very admirable as well as in demand due to its advantageous implementations in the construction of buildings. Castellated beams are trending currently and have multiple options to display too. The key part is, it is having openings in its web portion. These Beams are those which are fabricated from standard hot rolled steel I- sections by cutting along its web in "zigzag" pattern and thereafter rejoining the two halves on one another by welding together to form a castellated beam, so that generally the depth of a section will be increased by 1.5 or 1.33 times overall depth of the standard beam. Equal strength in tension & compression, easy construction, permits large span construction, real initial & life-cycle cost, strength, the speed of construction are the main factors for using steel as a building material. The aim is to compare between Standard I section and castellated beam with the hexagonal opening for different span length and for that find out the optimum size of the beam and compare its weight and deflection.
