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 […]
EK587
When the compression flange width to thickness ratio is larger, the compression flange may buckle locally before the complete plastification of the section occurs and the plastic moment is reached. […]
EK586
Provided the section can also sustain the moment during the additional plastic hinge rotation till the failure mechanism is formed. Such sections are referred to as plastic sections.
EK444
The point in each normal section of a member through which the axis passes and about which the section twists is called the shear center.
EK221
The degree of warping that takes place depends on the shape of the section, and is most pronounced in thin walled channels.
EK220
Both components of torsion produce shear stresses parallel to the walls of the section, and their combined effects can locally be greater than the effects of St. Venant alone.
EK216
Torsion in a section can be generated by a transverse load if the resultants of the shear stresses in the elements of the section produce torque. To counteract this, 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 […]
EK45
Let the beam be subjected to bending in the plane of symmetry. If the bending moment is small, the stress and the strain vary linearly across the section. When the […]
