The formulas to calculate the Pier Footing Size (S) are:
\[ \text{S} = \text{D} \times 2T \]
or
\[ \text{S} = \text{D} \times 1.1 \]
Where:
A pier footing is a square piece of construction that is used as a base support for the creation of a pier. The size of the footing depends on the diameter of the pier beams. Proper sizing ensures stability and strength of the structure.
Let's assume the following values:
Using the formulas to calculate the Pier Footing Size:
\[ \text{S} = 24 \times 2 \times 12 = 48 \text{ inches} \]
or
\[ \text{S} = 24 \times 1.1 = 26.4 \text{ inches} \]
The Pier Footing Size based on thickness is 48 inches, and based on diameter is 26.4 inches.
