WebLTB regions. Members that have lateral unbraced lengths that fall between Lp and Lr are designed for inelastic LTB buckling, where Lp is the limiting unbraced length at which the nominal plateau strength may be achieved under uniform bending and Lr is the limiting unbraced length at which yielding effects start to influence the nominal resistance. WebUNBRACED BEAMS Lateral-torsional buckling strength can be determined by using the C b expression give by Eq. 2 provided that the unbraced length is defined between points of zero twist. The buckling moment is compared to the maximum applied moment within the unbraced length under consideration. Eq.

WebTherefore, the effective length factor k for this case is equal to 0.5. Effective length factors for columns with idealized supports can be determined from Fig. 4.2. It may be of interest to note that k varies between 0.5 and 1.0 for laterally braced columns, and 1.0 and ∞ for unbraced columns. A discussion
