Abstract

Welded joints are critical components in steel structures because they experience high stress concentrations and have the potential to cause structural failure. This study aimed to analyze the strength of welded joints on the structuraL Profile used as a drainage pipe support in a grouting tunnel using the Finite Element Analysis (FEA) method. The study employed a quantitative experimental approach through three-dimensional modeling and simulation using ANSYS software. The analysis focused on equivalent stress, total deformation, and safety factor under static loading conditions with variations in loading point distances of 17.5 cm, 35 cm, and 67.5 cm from the support point to evaluate the effect of load distribution on structural response. The results showed that the highest stress concentration occurred in the weld toe and weld root areas, which are critical regions susceptible to structural failure. Variations in loading position significantly affected the stress distribution and deformation of the structure, where greater loading distances from the support point tended to increase stress and deformation values. However, the structure still satisfied the minimum safety factor requirements based on AWS and AISC standards. The findings demonstrate that the FEA method is capable of effectively predicting structural behavior and providing recommendations for optimizing welded joint design in drainage pipe support structures.
