Concrete Floor Design Load

And if you don t calculate correctly you ll have an expensive repair on your hands.

Concrete floor design load.

You can however calculate the load capacity of concrete in a quick and general way. The dead load on a floor is determined by the materials used in the floor s construction. Floor loading calculations help you make better racking decisions. 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.

If there s wall board covered ceiling suspended from the underside of that floor the dead load increases to about 10 pounds per square foot. The actual average cylinder strength for the floor concrete was 3630 psi. Load capacity of simply supported concrete slabs engineering toolbox resources tools and basic information for engineering and design of technical applications. 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. Four months after the floor was placed 10 cores were drilled measured and tested in compression. 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. A typical wood frame floor covered with carpet or vinyl flooring has a dead load of about 8 pounds per square foot.
