Deck Strength Calculator

Formula

The formula to calculate the deck strength is:

\[ DS = \frac{L}{A} \]

Where:

\(DS\) is the deck strength (pounds per square foot)
\(L\) is the load on the deck (pounds)
\(A\) is the area of the deck (square feet)

What is Deck Strength?

Deck strength is a measure of how much weight a deck can support over its entire surface area. It is typically expressed in pounds per square foot (psf) and is a critical factor in ensuring the safety and longevity of a deck structure. Proper calculation of deck strength is essential for compliance with building codes and to prevent structural failures.

Example Calculation 1

Let's assume the following values:

Load on the Deck (L) = 5000 pounds
Area of the Deck (A) = 200 square feet

Using the formula:

\[ DS = \frac{5000}{200} = 25 \, \text{psf} \]

The Deck Strength is 25 pounds per square foot.

Example Calculation 2

Let's assume the following values:

Load on the Deck (L) = 7500 pounds
Area of the Deck (A) = 300 square feet

Using the formula:

\[ DS = \frac{7500}{300} = 25 \, \text{psf} \]

The Deck Strength is 25 pounds per square foot.
