6 Concrete Floor Load Bearing

For 6 to 10 thick slabs on grade with k values between 100 pci and 200 pci the increase in stress i due to a 2nd wheel or post load as a percentage of stress for a single wheel or post load is approximately 15 to 20 for a wheel or post spacing of 3 to 4.

6 concrete floor load bearing.

This is the standard psi of a common mix. Static loads include for example block stacking equipment and machinery and storage racking systems. If you are doing a smaller home project with no special accelerants added to your mix your load bearing strength per concrete yard will be 3 000 psi. Static and dynamic loadings.

The dead load on a floor is determined by the materials used in the floor s construction. Forklifts pallet stackers and other. For concrete ground floors refer to chapters 5 1 substructure and ground bearing floors and 5 2 suspended ground floors. 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 load carrying capacity of a floor varies as the square of the floor thickness. For wheel or post spacings of 5 to 15 the increase in stress is. Write this number down. Dynamic loadings include material handling equipment mhe and other traffic including.

A typical wood frame floor covered with carpet or vinyl flooring has a dead load of about 8 pounds per square foot. If that s the case it takes some math and the numbers will be slightly fudged as the weight is not perfectly distributed to ea. This is the base load bearing strength of your concrete. Load bearing concrete slabs on ground face two types of loadings.

You can estimate the expected change in floor load carrying capacity due to reducing the thickness from 6 inches to 5 62 inches instead of 6 inches as follows. It sounds like you are asking what thickness and psi strength is needed to hold a fully loaded semi truck and trailer. 500 kg m 2 is typical for office storage space and similar. This note reflects the specific mix you will order throughout your project.
