6 Concrete Floor Load Bearing

Imposed loads varies from approximately 1 5 kn m 2 153 kg m 2 in domestic buildings to approximately 10 kn m 2 1053 kg m 2 in heavy industrial areas.

6 concrete floor load bearing.

It sounds like you are asking what thickness and psi strength is needed to hold a fully loaded semi truck and trailer. 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. Forklifts pallet stackers and other. A typical wood frame floor covered with carpet or vinyl flooring has a dead load of about 8 pounds per square foot.

This note reflects the specific mix you will order throughout your project. 5 62 6 squared 0 88. The load carrying capacity of a floor varies as the square of the floor thickness. 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.

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. Static loads include for example block stacking equipment and machinery and storage racking systems. Concrete floors may be used with lsf and may be constructed using either thin precast units or in situ concrete placed on steel decking.

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. Static and dynamic loadings. Load bearing concrete slabs on ground face two types of loadings. This is the base load bearing strength of your concrete.

For concrete ground floors refer to chapters 5 1 substructure and ground bearing floors and 5 2 suspended ground floors. 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. For wheel or post spacings of 5 to 15 the increase in stress is. The dead load on a floor is determined by the materials used in the floor s construction.
