6 Concrete Floor Load Bearing

5 62 6 squared 0 88.

6 concrete floor load bearing.

A typical wood frame floor covered with carpet or vinyl flooring has a dead load of about 8 pounds per square foot. Load bearing concrete slabs on ground face two types of loadings. This is the standard psi of a common mix. 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.

For concrete ground floors refer to chapters 5 1 substructure and ground bearing floors and 5 2 suspended ground floors. Dynamic loadings include material handling equipment mhe and other traffic including. 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. It sounds like you are asking what thickness and psi strength is needed to hold a fully loaded semi truck and trailer.

The load carrying capacity of a floor varies as the square of the floor thickness. Concrete floors may be used with lsf and may be constructed using either thin precast units or in situ concrete placed on steel decking. This is the base load bearing strength of your concrete. 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.

Write this number down. Static and dynamic loadings. Forklifts pallet stackers and other. Static loads include for example block stacking equipment and machinery and storage racking systems.

500 kg m 2 is typical for office storage space and similar. 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. This note reflects the specific mix you will order throughout your project. 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.
