نبذة مختصرة : This study investigates the web crippling behavior of austenitic stainless-steel channel sections under interior one-flange loading conditions, with a focus on enhancing predictive accuracy through Finite Element Analysis (FEA) using ANSYS 2024 R2. The primary objectives are to develop and validate a detailed numerical model for simulating web crippling and combined bending-crippling failures, and to conduct a comprehensive parametric study to evaluate the influence of key geometric and material properties. A total of 300 simulations were performed to examine the effects of yield strength, inside bent radius, section thickness, and bearing length on structural response. The results reveal that web crippling strength varies linearly with yield strength and bearing length, with increases of 6–7% and 10% observed for respective parameter enhancements. Thickness emerged as the most influential parameter, with a 20% increase resulting in approximately 35% gain in crippling strength. Conversely, an increase in inside bent radius led to a reduction in strength, particularly for thicker sections, likely due to induced eccentricities. The study provides essential insights into the mechanics of web crippling in thin-walled stainless-steel sections and establishes a validated modeling approach for future design optimization and code development.
