Proportioning reinforced concrete structural members by ultimate-strength design is based on the following assumptions: Strain in concrete is the same as in reinforcing bars at the same level, provided that […]
EK244
The modulus of elasticity can be defined as the change of stress with respect to strain in the elastic range.
EK93
Assumptions of the Bernoulli-Euler theory of bending: The beam is bent by pure terminal couples so that shear and axial forces are not present. The deformations are small, so that […]
EK84
Increase in strain does not increase the stress beyond the value of the yield stress.
EK68
When the material of a structural component is stressed beyond its elastic limit, the stress will seize to be proportional to the strain, Hooke’s law will no longer apply, and […]
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 […]
EK44
On the plastic approach the strain and stress are proportional to one another up to the yield stress at which the strain increases indefinitely without any further increase in stress.
EK36
Plane strain is defined by the case that the strain in one direction is completely restricted.
