Buckling#Lateral-torsional buckling

The term lateral-torsional buckling, outdated also known as tipping, refers to the failure of a carrier by a bending moment, the pressurized voltage parts of the structure fail by buckling. The carrier is bent and twisted at the same time. Because of the high risk potential of this form of component failure, the flexural -torsional buckling is examined in detail in the stability theory for the practical design of structural components are proven formulas and tables.

Generally one can say that the risk for a carrier to fail by lateral-torsional buckling, is the lower, the more approximate the smallest and the largest area moment of inertia of the corresponding cross-section. For this reason, the classic steel beams and sleek wood trusses are particularly vulnerable. In addition, the mounting of the carrier and its capacity to play a role in torsion closed hollow sections such as pipes are particularly resistant.
