Especially for rough interfaces, shear stresses lead to crack openings with vertical displacements longitudinal strain develop in the reinforcing bars. If the reinforcement bars are sufficiently anchored at both sides […]
EK559
Although tension stiffening has a minor influence on flexural strength, additional stiffness is provided at all sections, except right at the crack, and this has a significant effect in decreasing […]
EK541
Passive confinement is engaged only after crack deformations in the concrete ring develop that induce tension forces in the surrounding steel. The surrounding steel restricts the propagation and widening of […]
EK464
Contraction joints, in effect, are deliberately made weakness planes. They are formed in the expectation that if a crack occurs it will be along the neat geometric pattern of a […]
EK295
If shear reinforcement is not provided, shear resistance in reinforced concrete members is developed by a combination of the following mechanisms: Shear resistance of the uncracked concrete. From 20% to […]
EK201
A basic assumption in shear friction method is that a crack will form at a potential failure plane where direct shear stresses are high or at actual planes of weakness […]
EK134
Once initiated, the crack may propagate in a ductile (or stable) fashion for which the external forces must supply the energy required to tear the steel.
EK133
Brittle fracture is initiated by the existence or formation of a small crack in a region of high local stress.
EK130
Structural steel may fracture at low average tensile stresses after a large number of cycles of fluctuating load. This high-cycle fatigue failure is initiated by local damage caused by the […]
EK118
A reinforced concrete beam will initially behave elastically throughout, as the applied uniform moment is increased. When the limiting tensile strain for the concrete is reached a crack will form, […]
