When a primary flexural crack forms and crosses the reinforcing steel, the concrete adjacent to the crack slips against the steel. Slip, or bond-slip, is defined as the relative movement […]

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 […]

The distribution and magnitude of bond stresses along a bar are difficult to establish quantitatively. One problem is the progressive shifting of the bond distribution along the bar as bond […]
EK535
After adhesion is lost and ribs begin to bear on the concrete, slip occurs by progressive crushing of the porous concrete paste structure in front of the rib. The compacted […]

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.
