Section E(Tile Calculations)
For Moment based tile systems,choose either Method 1 or 2.Compare the values for Mr with the values from Mf.If the Mf values
are greater than or equal to the Mrvalues,for each area of the roof,then the the attachment method is acceptable.

*Must be used in conjunction with a list of moment based tile systems
•For Uplift based tile systems use Method 3.Compare the values for F'with the values for Fr If the F'values are greater than or
equal to the Fr values,for each area of the roof,then the tile attachment method is acceptable.
