An experimental and analytical study was conducted to evaluate the effects of induced deformation caused by the thermal elongation of connected heated steel beams on the buckling behavior of steel columns at increasingly higher temperatures under a constant axial load. The buckling tests were performed using steel columns (SN490B JIS grade) with rectangular cross-sections. The result of tests indicated that the reduction in the column failure temperature Tcr due to induced deformation can be from 10℃ to 50℃. depending on the axial force ratio. And also, the behavior of tests were simulated by the one-dimensional finite-element procedure, and the evaluation of the effect of induced joint translation angle on the column failure temperature Tcr was carried out.
