season.)

draw a vertical line from the rate of placing until it intersects the correct concrete temperature line. Then read left

horizontally from the point of intersection to the left margin of the graph and determine the maximum concrete

pressure in 100 lb/sf.

Table 3-1 for board sheathing and Table 3-2 for plywood sheathing. Refer to the column headed Maximum

Concrete Pressure and find the value you have for the maximum concrete pressure. If the value you have falls

between two values in the column, round it up to the nearest given value. Now move right to the column

identified by the sheathing thickness you are using. (Use the strong way for plywood when possible.) This

number is the maximum stud spacing in inches.
