Concrete floor design load.

The actual average cylinder strength for the floor concrete was 3630 psi. You can however calculate the load capacity of concrete in a quick and general way. A floor loading assessment is the evaluation of the concrete subfloor not the raised floor. To ensure that the concrete floor will continue to carry its design loading successfully it is vital to design and construct the subgrade as carefully as the floor itself.

The dead load on a floor is determined by the materials used in the floor s construction. The only way to specifically calculate the load capacity of concrete is to have a licensed structural engineer process the formulas and consult a myriad of tables that all apply to the specific design of your project. Four months after the floor was placed 10 cores were drilled measured and tested in compression. Pressures exerted on the subgrade due to loading are usually low because of the rigidity of concrete floor slabs and loads from forklifts wheels or high rack legs are spread.

However you should consider the weight of the raised floor in the floor loading formula. The specification for the floor of a maintenance building called for a 6 inch slab thickness and concrete with a design compressive strength of 3000 psi. A typical wood frame floor covered with carpet or vinyl flooring has a dead load of about 8 pounds per square foot.
