Tests for the tensile strength of plain concrete fall into one of three classifications, each with its own characteristic set of results: Direct tension. Flexural tension or modulus of rupture. […]
EK421
The principal advantages of butt welds are the simplicity of the joint and the minimal change of the stress path. Static tension test results indicate that their average tensile strength […]
EK419
Care is needed in detailing welded joints of the T and corner type, where restrained weld shrinkage forces are transmitted through the weld into a plate in the through-thickness direction. […]
EK355
A brittle material fractures when the applied stress reaches the ultimate tensile strength of the material.
EK273
Usually secondary flexural cracks are widely spaced, and one crack does not influence the formation of others. They are expected to occur under low loads, such as dead loads. When […]
EK263
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 […]
EK243
Shear strength may be considered as 20% to 30% greater than the tensile strength of concrete, or about 12% of its compressive strength.
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 […]
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 […]
EK120
Torsional moments produce shear stresses which result in principal tensile stresses inclined at approximately 45 degrees to the longitudinal axis of the member. Diagonal cracking occurs when these tensile stresses […]
EK86
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 […]
EK66
Although tension stiffening has a minor influence on flexural strength, additional stiffness is provided at all sections, except right at the cracks, and this has a significant effect in decreasing […]
