Concrete Floor Reinforment Per Pressure

This note reflects the specific mix you will order throughout your project.

Concrete floor reinforment per pressure.

Footings for pier founda tions shall be reinforced concrete and should be placed level on firm undisturbed soil. 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. Typical and assumed distribution of concrete lateral pressure on formworks. Nuts and washers tightly applied.

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. Pier and column footing requirements. X 150 x 6 height of pour equals 3600. This is the base load bearing strength of your concrete.

Per tie x 150 x height of pour pressure per tie. Formula for wall form pressure. Calculation of lateral pressure on concrete formwork. 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.

This is the standard psi of a common mix. Where vertical reinforcing of walls is required anchor devices shall align with the reinforcing. Wall will be 6 inches. 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.

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. 7 into concrete or masonry. 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. 150 at 1 300 at 2 450 at 3 etc.

3 reinforcing bars at 16 or 18 inches on center are the most common reinforcing schemes used on. It sounds like you are asking what thickness and psi strength is needed to hold a fully loaded semi truck and trailer. 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. 2 x2 tie pattern equal 4 sq.

Aci 347 04 specify that concrete lateral pressure is computed as per equation 1 if fresh concrete slump value is greater than 175 mm and does not placed with normal internal vibration to a depth of 1 2 m. Concrete pressure compounds with the height of the pour.
