Pull-out Resistance (Grouting)
The method of analysis is selected in the section "Pull out resistance (grouting)".
Setting of analysis for pull out resistance (grouting)
This bearing capacity determines a pullout resistance from the root and is calculated equally for prestressed bar and strand anchors.
Option "Calculate from shear strength"
diameter of the anchor bar (strand diameter corresponding to the strand area)
shear strength between the anchor bar and grouting
Option "Calculate from concrete strength"
It is the same analysis as in the previous case, the shear strength τ is calculated from the parameters of concrete according to the different standards:
- EN 1992-1-1 (EC2)
coefficient of cohesion (1,0 for good conditions of cohesion, 0,7 in other cases)
concrete strength in tension - obtained from fck by formulas; ≤ C60/75 value
- ACI 318-11
concrete strength in compression
- GB 50010-2010
coefficient of reinforcement type
1,47 – 7-strand
1,56 – 3-strand
1,79 – plain reinforcement bar
1,92 – ribbed steel wire
design concrete strength in tension; ≤ C60 value
Option "input bearing capacity per unit length"
pull out resistance [kN/bm, lbf/ft] from grouting per unit length
The value of pull out resistance (grouting) is entered Rc [kN, lbf]
