The bending mechanism is decisive for dowel action. The mechanism of shear is subordinate and kinking only occurs after very large interface displacements and is therefore neglectable for common building […]
EK673
The activation of dowel action in the reinforcement bar occurs due to relative horizontal displacement of old and new concrete layer. For dowel action, it can be distinguished between the […]

Buildings with a height to width ratio smaller than one will mainly act as shear structures and the shear walls can be designed on a floor-to-floor basis. In taller buildings […]

Calculation of the stresses in a thin shell generally is carried out in two major steps, both usually involving the solution of differential equations. In the first, bending and torsion […]
EK415
Thick plates undergo single curvature bending under flexure and attract prying forces.
EK414
Medium thickness end plates undergo single curvature or limited double curvature bending causing the end plate edges to also contact the support surface, creating new reaction points thereby increasing the […]
EK413
Small thickness end plates undergo pronounced double curvature bending and do not attract prying action.

Relative deformation capacities of the elements in the load path: Plates in bending. Relatively large elastic deformation. Large deformation capacity when plastic hinges form. Plates in tension and plates in […]
EK242
Ultimate tensile strength of concrete beam in bending is greater than the tensile stress obtained obtained by direct or splitting tests. Flexural strength is expressed in terms of the modulus […]
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 […]
EK213
When a beam is bent elastically by a system of transverse loads, plane sections no longer remain plane after bending, but are warped by shear strains.

Where longitudinal bending reinforcement is required, the additional torsional steel area may either be provided by increasing the size of bars provided, or by additional bars.
EK122
The calculated amounts of torsional reinforcement must be provided in addition to the full bending and shear reinforcement requirements for the ultimate load combination corresponding to the torsional moment considered.

The total lateral deflection of a rigid frame may be considered a combination of the following: Cantilever deflection due to axial deformation of columns (15% – 20%). Frame shear racking […]

Figure represents the distribution of principal stresses across the span of a homogeneous concrete beam. The direction of the principal compressive stresses takes the form of an arch while the […]

When the deflections of the plates middle plane is small compared with the thickness it can be assumed that: There is no deformation in the middle plane. The normals of […]

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 […]

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 […]
EK31
In the elementary theory of bending, stresses and deflections in beams are directly proportional to the applied loads. This condition requires that the change in shape of the beam due […]
