چکیده مقاله
This study presents a validated finite element model for a steel I beam with a partially corrugated web PCW , focusing on its shear behavior under four point bending The model was developed in ABAQUS software and calibrated using experimental results from a previously tested specimen PCW S 2 3 Both linear buckling and nonlinear post buckling analyses were performed, employing a bilinear elastic plastic material model and Riks method for tracking post peak response Mesh sensitivity analysis revealed that accurate detection of boundary buckling near the transition zone between flat and embossed web regions requires local refinement An optimized mesh with global seed size of 7 and localized refinement in the web boundary zone seed = 10 showed excellent agreement with the experimental load displacement response Since the test did not report geometric imperfections, an imperfection sensitivity study was conducted Thirty buckling modes were extracted and tested with different amplitudes Among them, Mode 25 with an amplitude of L/1000 Analysis 5 provided the best match in terms of both failure shape and load displacement behavior Additionally, an analysis was carried out to investigate the effect of transverse stiffener placement in set up of four point bending test relative to the boundary zone Results showed minimal influence on global shear behavior, confirming the model's robustness The proposed model successfully replicated the experimental behavior and provides a reliable basis for future design and optimization studies of PCW beams
