Abstract Corrugation profoundly impacts the strength and durability of I-section structures in structural engineering. This project focuses on analyzing two distinct types of corrugationstrapezoidal and triangularusing advanced computation platforms like Ansys Workbench for Finite Element Analysis (FEA). Our primary objective is threefold: firstly, to discern how these different corrugation forms influence the robustness and weight distribution within an I-section structure. Secondly, by leveraging FEA simulations on the Ansys Workbench platform, we aim to precisely compute and compare their individual strength-to-weight ratios, providing crucial insights into their structural performance. Lastly, the project aims to formulate definitive conclusions from these analyses, offering valuable inputs for future studies or applications in materials science and civil architecture disciplines where such knowledge is indispensable. Through this investigation, we seek to advance understanding in structural engineering and contribute to the optimization of design methodologies, thereby fostering innovation in related fields

1. INTRODUCTION

   1. sections have a high strength-to-weight ratio and effective stiffness qualities, which make them useful in a variety of engineering structures. Nonetheless, the web of an I-section frequently continues to be a somewhat inefficient component since a large amount of material is concentrated in places that don't really add to the overall strength or stiffness. By carefully adding more material and raising the web's moment of inertia, corrugation can provide a viable way to increase efficiency. Because of the element's increased stiffness and rigidity from its corrugated design, it can support a greater load without bending or deflecting unduly. This is especially helpful for bridges, which must sustain high traffic volumes. When designing corrugated shapes, less material is needed than for flat ones to have the same strength. This may result in less

      money being spent and a lighter structurewhich is necessary for lengthy spans. Additionally, by more efficiently channelling loads, the corrugated design can increase the structure's efficiency. This may lengthen life and assist lower concentrations of stress. An eye-catching accent can be added with corrugated shapes. This may be particularly crucial for vehicles or aircraft. Aerospace and automotive structures utilize corrugate

      structure stiffness without appreciably increasing its bulk.In order to save weight and maximize strength and stiffness, corrugated steel webs are utilized in both automotive and aviation constructions. The corrugations give the structure stiffness without appreciably increasing its mass since they function similarly to ribs.

6. MESH DEPENDENCY

   When performing finite element analysis (FEA) simulations with Ansys or other comparable software, mesh dependency is a crucial factor to take into account. It speaks about the simulation results' sensitivity to changes in the mesh density and quality that are applied to the geometric model. The density of the mesh, which is determined by the quantity and dimensions of finite elements utilized to discretize the model, has a major impact on the analysis's precision and computing effectiveness. Although a finer mesh frequently necessitates more computer power and longer simulation durations, it can capture more minute aspects of the geometry and produce results with more realism. The quality of the mesh's elements is just as important as its density. Highly deformed or skewed elements are examples of poorly shaped elements that can cause numerical instability and imprecise forecasts. Ansys provides instruments for evaluating and enhancing element quality, guaranteeing the mesh's resilience and dependability. To assess mesh dependency, mesh convergence studies are frequently carried out. These investigations involve running simulations with increasingly finer meshes until a stable solution is reached. Convergence study results are useful in figuring out the ideal mesh density needed to produce precise and trustworthy results for a certain investigation. In mesh dependency management, accuracy and computational efficiency must be balanced. Based on the intricacy of the model, the physics involved, and the required degree of detail in the output, engineers must optimize the mesh density. In crucial areas of the model, local mesh refinement can be used to improve resolution were enquired without sacrificing total effectiveness. To further evaluate the accuracy of the model, simulation findings must be validated against experimental data. This validation procedure depends on mesh dependency studies, which guarantee that the simulation faithfully captures the physical behaviour of the system under study.
