Structural Analysis of Castellated Beams with Web Openings of Different Forms using Finite Element Method

Castellated beams are increasingly important in modern structural engineering due to their enhanced strength-toweight ratio, material efficiency, and versatility in various applications. These beams, formed by cutting and reassembling standard I-beams, offer significant advantages in reducing weight while maintaining or improving structural capacity. The present research focuses on the analysis of castellated beams using Finite Element Method (FEM) software to evaluate their behavior under various loading conditions. The study employs FEM to model these beams, simulating stress distribution, deformation, and failure modes across different configurations and loading scenarios. Factors such as span length, load type, and geometric variations are considered to assess their influence on performance. The findings provide valuable insights into the optimal design and application of castellated beams, contributing to the development of lightweight, strong structures in modern construction and supporting the advancement of sustainable engineering practices
