Notes and Changes:

v4:
1) LRFD load cases instead of ASD load cases
2) Correct minimum support height and FCT pitch angle in Figure 1
Update 2022.07.28 - replaced .xlsx file with updated calculations of different cases used in establishing LLO decisions, such as T2200276 (see tab "anchor resistance -v4 additions")
