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