This calculator calculates the maximum wall load(in plf) using concrete compressive strength (in psi or kpa), modulus of subgrade reaction(in pci or mpa/m), slab thickness(in or mm) values.
Formula:
P = 9.93 ( fc^0.5 )( te^2 ) ( ( k / (19000 ( fc^0.5 )( te^3 ) ) ) ^ 0.25
Where,fc = Concrete compressive strength,
k = Modulus of subgrade reaction,
te = Slab thickness
