# Concrete slab maximum wall load

Calculate maximum wall load of concrete slabs with our easy-to-use calculator. Get fast, accurate results in no time.

Use this online calculator to determine the maximum wall load that the edge of a concrete slab-on-grade floor can support. Simply input the compressive strength, modulus of subgrade reaction, and slab thickness, and the calculator will provide you with the maximum wall load in pounds per linear foot. Ensure the structural integrity of your concrete floor by accurately assessing its load-bearing capacity with this convenient tool.

P = 9.93 \left( \sqrt{fc} \right) \left( te^2 \right) \left( \left( \frac{k}{{19000 \left( \sqrt{fc} \right) \left( te^3 \right)}} \right) ^{0.25} \right)

The variables used in the formula are:

fc = Concrete compressive strength,

k = Modulus of subgrade reaction,

te = Slab thickness.
