Temporary Rock Anchors
Temporary Rock Anchors
(OP)
The PTI Manual recommends a design load of 0.6 times the specified minimum tensile strength of the steel bar. Has anyone ever designed TEMPORARY anchors using a higher factor, and if so, what was your basis for the higher factor?

Also - if your specs need you to test to more than 133%, like say 150% DL, then you have to design around even lower than 0.6. This often happens on DOT jobs as PEinc mentioned.
