Concrete Floor Reinforment Per Pressure

It sounds like you are asking what thickness and psi strength is needed to hold a fully loaded semi truck and trailer.

Concrete floor reinforment per pressure.

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. 7 into concrete or masonry. Formula for wall form pressure. Thus the reinforcing is supposed to enhance aggregate interlock which normally cannot be depended upon for long term load transfer of repetitive loads if the crack is 0 025 to 0 035 inches or wider per portland cement association s research.

Write this number down. 2 x2 tie pattern equal 4 sq. Per tie x 150 x height of pour pressure per tie. 9 7 residential slabs with post tensioned reinforcement for structural action 9 8 design for slabs on expansive soils 9 9 design for slabs on compressible soil chapter 10 fiber reinforced concrete slabs on ground p.

Concrete pressure compounds with the height of the pour. 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. Table r401 4 1 presumptive load bearing values of foundation materials a class of materials load bearing pressure pounds per square foot crystalline bedrock 12 000. Wall will be 6 inches.

This note reflects the specific mix you will order throughout your project. X 150 x 6 height of pour equals 3600. 500 kg m 2 is typical for office storage space and similar. 3 reinforcing bars at 16 or 18 inches on center are the most common reinforcing schemes used on.

The minimum reinforced concrete footing thickness will be 6 inches or 1 1 2 times the length of the footing projection from the foundation wall whichever is greater. 150 at 1 300 at 2 450 at 3 etc. This is the standard psi of a common mix. Calculation of lateral pressure on concrete formwork.

Typical and assumed distribution of concrete lateral pressure on formworks. Pier and column footing requirements. Footings for pier founda tions shall be reinforced concrete and should be placed level on firm undisturbed soil. 360r 45 10 1 introduction 10 2 polymeric fiber reinforcement 10 3 steel fiber reinforcement.

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. Nuts and washers tightly applied.
