Local buckling of steel cold-formed profiles under transverse bending [PDF]

Строительство уникальных зданий и сооружений, 2014
Danger local buckling (LPA) are virtually ignored in most engineering methods for calculating the cross-section profiles with complex shapes. The problem of LPA rod is reduced to the problem of overall sustainability.
