Experimental investigation on structural behaviour of castellated column under axial load

Patil, Rupali A. / Salgar, Pramod B.

Since the last decade, Castellated steel sections are being used in steel constructions for their valuable characteristics, such as being lightweight, having superior aesthetics, a higher strength-to-weight ratio, and comfort to handlement. A steel I-section that has been modified to have two portions split longitudinally along its web in a particular arrangement is kNown as a castellated steel column. The two cut portions are reconnected after moving to produce a perforated column with a larger width and strength. Castellated steel columns (CSC) are divided into groups according to the many types of job openings that are available in the component i.e. hexagonal, circular, diamond, sinusoidal, octagonal, etc. are a few of the most popular opening shapes. According to studies, the introduction of differently shaped web openings affects the structural behaviour of CSC. In this experimental investigation, the behaviour of CSCs with circular and diamond-shaped openings has been studied under axial loading and validated the results by using the ANSYS software. According to the results, the load-carrying capacity of the CSC with circular-shaped openings (with MS stiffener) is on average 17.3% higher than that of the CSC with circular-shaped openings (without stiffener). The load- carrying capacity of the CSC with diamond-shaped openings (with MS stiffener) is on average 6% higher than the load-carrying capacity of the diamond-shaped openings (without stiffener). The study concludes that the CSC with circular openings performs better than the CSC with diamond openings.
