Concrete Floor Reinforment Per Pressure

Wall will be 6 inches.

Concrete floor reinforment per pressure.

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. 3 reinforcing bars at 16 or 18 inches on center are the most common reinforcing schemes used on. Write this number down. Where vertical reinforcing of walls is required anchor devices shall align with the reinforcing.

Footings for pier founda tions shall be reinforced concrete and should be placed level on firm undisturbed soil. 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. 2 x2 tie pattern equal 4 sq. Formula for wall form pressure.

360r 45 10 1 introduction 10 2 polymeric fiber reinforcement 10 3 steel fiber reinforcement. 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. It sounds like you are asking what thickness and psi strength is needed to hold a fully loaded semi truck and trailer.

150 at 1 300 at 2 450 at 3 etc. Nuts and washers tightly applied. 500 kg m 2 is typical for office storage space and similar. 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.

7 into concrete or masonry. 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. 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. 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.

Per tie x 150 x height of pour pressure per tie. This note reflects the specific mix you will order throughout your project. Calculation of lateral pressure on concrete formwork. Pier and column footing requirements.

This is the base load bearing strength of your concrete. X 150 x 6 height of pour equals 3600.
