approximately 0.5 and 0.9. However, L r is found bounding for all cases if the 90% factor is taken into account for the option 1 curve. The R6 option 2 curve has similar trends to the option 1 curve. The R6 option 2 curve is conservative for all cases at lower L r (<0.7). For higher loading (L r >0.7), the R6 option 2 curve is found bounding if the 90% factor is taken into account.
