QUESTION: Is Mcr  reported in the "Ultimate Moment Table" different from that reported in the "Vertical/horizontal shear Table" ?

ANSWER:

Mcr reported in the ultimate moment table is the cracking moment which includes both live load and dead load So the values are high.

Mcr reported in the vertical shear is Moment causing flexural cracking of section due to externally applied loads (beyond Dead Load) so this value is used for Rating and the formula.
