WebJan 1, 2013 · It presents an analytical solution for lateral-torsional buckling of CFSS. It examines interactions between compression and bending when channel beams buckle. … Webof web slenderness by requiring a separate web local buckling (WLB) limit state check. Lateral-torsional buckling (LTB) and flange local buckling (FLB) are investigated as separate and independent failure modes. As a result, the WLB resistance is handled in effect as a cap on the LTB and FLB strengths.
