BUCKLING CAPACITY OF COLD-FORMED STEEL SECTIONS WITH WEB HOLES USING DIFFERENT APPROACHES
Abstract
This study examines the buckling behavior of cold-formed steel sections with web holes under bending. Perforated sections are widely used in structural applications to accommodate openings for electrical, plumbing, and ventilation systems. However, these holes significantly affect the section's mechanical properties and buckling behavior. Elastic buckling analyses were conducted for both perforated and non-perforated sections using CUFSM, considering variables such as hole height, hole length, and section height. Additionally, the effectiveness of different approaches in predicting local and distortional buckling capacities was compared. The results indicate that hole height and hole length significantly influence buckling capacity. In particular, when the hole length exceeds 80 mm, local buckling capacity increases, while distortional buckling capacity decreases. Furthermore, comparison of different methods revealed that the approach developed by Moen and Scahfer produced results similar to standart approaches, whereas some other methods tended to overestimate the local buckling capacity and underestimate the distortional buckling capacity.
