Shear buckling resistance may conveniently be improved by dividing the web into a series of panels by using intermediate vertical stiffeners.
EK629
Shear buckling occurs largely as a result of the compressive stresses acting diagonally within the web.
EK595
Intermediate transverse stiffeners must be proportioned so as to satisfy two conditions: 1) They must be sufficiently stiff not to deform appreciably as the web tends to buckle.2) They must […]
EK594
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.
EK589
Presence of shear strains causes the section to warp. Its effect in the flanges is to modify the bending stresses obtained by the simple theory, producing higher stresses near the […]
EK580
Web stiffening may be required for plate girders to prevent shear buckling.
EK387
Where rigid beam-to-column connections are used, some kind of column stiffening is normally required. Horizontal stiffeners are used where the column web is overstressed by the concentrated load from the […]
EK386
Where the web and flanges are spliced, the axial load can be shared between the web and the flanges in proportion to their areas. However, in bolted connections it is […]
EK378
Bearing stiffeners are provided to prevent local crushing of the web due to concentrated loads or reactions applied through the flange.
EK377
In cases of patch loading (loads applied between the stiffeners), an additional check is required to ensure that the specified compressive strength of the web for edge loading is not […]
EK375
Load-carrying stiffeners are provided to prevent local buckling of the web due to concentrated loads or reactions applied through the flange. The stiffeners should be positioned wherever such action occur, […]
EK372
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 […]
EK369
The provision of vertical stiffeners enables the web to sustain shear stresses well in excess of its unstiffened elastic critical shear stress. Furthermore, additional strength is obtained as a consequence […]
EK214
The simple theory of bending is based on the assumption that plane sections remain plane after bending. In reality shear strains cause the section to warp. The effect in the […]
EK207
When a simply supported steel “I” beam bends under downward loads the extreme fibres at the top of the beam are in compression. This puts the top flange of the […]
EK206
Local buckling may be avoided by reducing the stress capacity of the section, and hence its bending moment capacity, if the slenderness of the web or the flange exceeds certain […]
EK182
If the principal tensile stress in the web reaches the tensile strength of concrete in an area containing no flexural cracks, an inclined crack may appear and shear tension failure […]
