초록

Not all structural columns maintain a vertical orientation. Several contemporary building structures have inclined columns, introducing distinct challenges, particularly in buckling behavior. This study examines the buckling behavior of inclined, thin-walled steel bundled columns, differing from typical vertical columns. Using specimens with three tubes welded to plates linearly aligned at the top and triangularly at the bottom, tests indicated that buckling capacity increases with tube wall thickness and diameter but decreases with column height. Inclined tubes in bundled columns showed improved buckling resistance over vertical ones. Results were verified against standard steel design guidelines to assess their predictive accuracy.
