The method of analysis is selected in the section "Tension strength".
Setting of analysis for anchor strength
Option "calculate"
The calculation is same for all types of anchors according to formula:
where: | fu | - | design strength of material |
A | - | area of the shaft of the anchor |
Option "input"
It is necessary to enter value of tension strength Rt [kN, lbf]
In the case of strand anchors it is necessary to enter area of one strand (option "input area" - total area is calculated according to formula:
where: | A1 | - | area of one strand |
n | - | number of strands |
In the case that the diameter of strand is entered (option "input diameter"), the total area is calculated according to formula:
where: | ds | - | diameter of one strand |
n | - | number of strands |
Strand anchor parameters input
