EK601
The cross section is not capable of resisting any additional moment but may maintain this moment for some amount of rotation in which case it acts like a plastic hinge.
EK600
The ratio of the plastic moment to the yield moment is known as theshape factor since it depends on the shape of the cross section.
EK340
Near a free boundary (i.e. no external applied forces) the shear stress on any cross-section must act in a direction parallel to the boundary.
EK337
The form of the distribution of shear stresses is dependent on the shape of the cross-section of the beam, and on the direction of application of the shearing force.
EK225
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 […]
EK147
As the load on a ductile steel beam is increased, the stresses in the beam also increase, until the yield stress is reached. With further increases in the load, yielding […]
EK124
A plastic hinge is said to form in a structural member when the cross-section is fully yielded.
EK81
Plastic moment is the moment resistance of a fully yielded cross-section, The cross-section must be fully compact to develop its plastic strength. The component plates of a section must not […]
EK47
The kern is the area around the center of gravity of a cross-section within which any load applied produces stress of only one sign throughout the entire cross-section.
EK39
The shear center is defined as the point on the cross-section of a beam through which the resultant of the transverse loads must pass so that the stresses in the […]
