Intermediate transverse stiffeners are provided to prevent out of plane buckling of web at the location of the stiffeners due to the combined effect of bending moment and shear force.

The plastic design method is based on the following assumptions: The material has the capacity to undergo considerable plastic deformation without danger of fracture. Ductility of steel (that is, a […]
One of the prerequisites of plastic frame analysis is that the structure will not fail by rupture (brittle failure) but by deformations, which may progressively grow without any increase in […]
Designing for tension field action imposes additional loading on the transverse stiffeners. Because of the additional compressive forces induced, the stiffener must be designed as a strut and checked for […]
Load-carrying stiffeners must be checked for both buckling and bearing.
The behaviour of a girder under an increasing shear load may be divided into the three phases: Unbuckled. The situation prior to buckling when equal tensile and compressive principal stresses […]
The buckling theory is based on the assumption that the ends of the column are pinned, that is, frictionless joints which prevent linear movement but which can rotate freely about […]
The Euler buckling theory makes no allowance for: Homogeneity of column material. Isotropy of column material. Variation of Young’s modulus and elastic-plastic behaviour of column material. Loading not axial. Residual […]
The effective length of a column is controlled by its end fixity. By effective length we mean that length of the column which is subjected to lateral buckling.
A strength gain is possible with plates in shear where tension field action is considered. Thin unstiffened plates cannot carry much load after buckling. The critical buckling stress is increased […]
There are two main assumptions for first order plastic analysis: The structure is made of ductile material that can undergo large deformations beyond the elastic limit without fracture or buckling. […]
Elastic buckling is a state of lateral instability that occurs while the material is stressed below the yield point.
