This study examines the structural performance of non-prismatic corrugated steel I beams with web openings, focusing on various corrugation profiles (trapezoidal and rectangular) and web heights. Through ANSYS Design Modeler software, a detailed comparative analysis of load-deflection performance identifies the most economical corrugation shape. The findings aim to develop efficient and reliable design guidelines, ensuring the safe and cost-effective use of steel beams with web openings in structural applications, including buildings and industrial facilities.
Trapezoidal corrugated steel I beams with circular openings represent an innovative and structurally efficient design in the realm of construction and engineering. These beams feature a trapezoidal corrugation pattern, providing enhanced strength and load-bearing capabilities while minimizing material usage. The incorporation of circular openings further adds to the beams' versatility, allowing for weight reduction without compromising structural integrity. This design not only contributes to costeffectiveness but also facilitates efficient installation processes. The trapezoidal corrugations increase the beams resistance to bending and torsional forces, making them suitable for a variety of applications, from industrial buildings to infrastructure projects.

In the realm of structural engineering, the utilization of rectangular corrugated steel I beams has garnered significant attention for its potential to balance structural efficiency and economic considerations. The integration of web openings in steel beams has emerged as a key innovation in structural engineering, offering the potential to enhance design flexibility and reduce overall weight by accommodating services and utilities within the structural elements. web openings introduces complexities that can significantly affect the stiffness and strength of steel beams, raising concerns about structural performance.
Fig -1: Trapezoidal Corrugated Web Rectangular corrugated webs in steel structures represent a significant advancement in structural engineering, offering a balance between efficiency and economy. The Rectangular configuration imparts unique characteristics to the web, contributing to enhanced structural performance. Rectangular corrugated webs are more efficient than triangular and trapezoidal corrugated webs. A circular web opening enhances beam efficiency and maximizes load-carrying capacity than other shaped openings.
While web openings offer economic benefits and additional structural support, they also pose a potential threat to the load-carrying capacity of beams. Design engineers often incorporate openings in plate elements to facilitate access for ducts, cables, repairs, and maintenance services. In commercial buildings, circular web openings are introduced to simplify the installation of water pipes. However, the introduction of these openings in the web region alters the stress distribution, thereby reducing the shear resistance of the web plate. Use of corrugated webs to provide enhanced shear stability and eliminate the need for transverse stiffeners.
