6 Concrete Floor Load Bearing

For concrete ground floors refer to chapters 5 1 substructure and ground bearing floors and 5 2 suspended ground floors.

6 concrete floor load bearing.

Dynamic loadings include material handling equipment mhe and other traffic including. It sounds like you are asking what thickness and psi strength is needed to hold a fully loaded semi truck and trailer. 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.

Forklifts pallet stackers and other. 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. This is the base load bearing strength of your concrete. The load carrying capacity of a floor varies as the square of the floor thickness.

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. This is the standard psi of a common mix. 500 kg m 2 is typical for office storage space and similar. 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.

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

Static and dynamic loadings. Write this number down. 5 62 6 squared 0 88. A typical wood frame floor covered with carpet or vinyl flooring has a dead load of about 8 pounds per square foot.
