Tension stiffening is only effective if a bond mechanism can transfer a tensile force between the steel and surrounding tensile concrete. The nature of the bond mechanism also changes at […]

Tension stiffening in a flexural member is the additional stiffness provided by the tensile stress in the concrete between primary flexural cracks. The tensile force in the concrete is transferred […]
Non-linear material effects in reinforced concrete are attributed to the stress-strain relationships for concrete and the reinforcing steel and also the bond breakdown between steel and concrete.
Response of the grouted vertical connectors was similar to the bond response of reinforcing bars in confined concrete. After the adhesion between the grout and the connector is lost, the […]
In the absence of confinement, deformed bars fail in bond by splitting.
Radial components of the bond forces are resisted by tensile stress rings in the concrete surrounding the bar.
In the case of deformed bars, bond stresses are transferred mainly by mechanical interlock.
Bond between reinforcing bars and concrete is made up of three components: chemical adhesion, friction, and mechanical interlocking of bar lugs (ribs) with the surrounding concrete.
Bond refers to the interaction between reinforcing steel and the surrounding concrete that allows transfer of tensile stresses between the steel and concrete.
When some bars are short, it is necessary to splice them by lapping the bars a sufficient distance to transfer stress through the bond from one bar to the other.
The joint behavior of steel and concrete in a reinforced concrete member is based on the fact that a bond is maintained between the two materials after the concrete hardens. […]
The factors involved in controlling main cracks are the reinforcement stress, the bond characteristics of reinforcement, the distribution of reinforcement, the diameter of the steel bars used, the steel percentage, […]
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 […]
Shear transfer by bond between precast and in-situ elements is possible when the shear stress is low.
Shear forces between adjacent precast concrete components can be transferred through bond, interface joint friction, interlocking by shear keys, dowel action of transverse steel bars or rods.
Bond and anchorage failure usually occurs when the slab is subjected to heavy concentrated loads near the support or when heavy loads are applied over a rather short span. The […]
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, […]
