    This document provides dimensional properties and design specifications for various IS steel beams, including an ISHB 450 beam and ISMB 550 beam. It also includes calculations for weld sizes, stresses, shear values, bending moments, deflections and other structural analyses for the beams. The analyses show that the weld sizes and stresses are within permissible limits.
