EK551
Plastic ducts do not provide confinement to the connector and grout, and appear to have a negative effect on the frictional resistance of the connection.
EK547
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 […]
EK543
When the pull on the bar is small, high stresses develop near the loaded end of the bar; some slip of the bar occurs as adhesion between the bar and […]
EK538
Confinement can be classified as either active or passive.
EK537
The splitting resistance of concrete can be enhanced if confinement stresses are superimposed onto the tensile ring stresses around the reinforcing bar.
EK534
If confinement is provided, usually by the use of stirrups and/or a large concrete cover, bond failure occurs by shear failure of the concrete keys between the steel ribs.
EK533
In the absence of confinement, deformed bars fail in bond by splitting.
