Slabs and individual beams can easily be overstressed or deflect so that mobile file carriages can drift. Related Topics . Five to six inches is recommended if the concrete will receive occasional heavy loads, such as motor homes or garbage trucks. Loads used in design load equations are given letters by type: D = dead load L = live load L r = live roof load W = wind load S = snow load E = earthquake load R = rainwater load or ice water load T = effect of material & temperature H = hydraulic loads from soil F = hydraulic loads from fluids. Pc = Pt/Ne: Mod. - 1 response - Report Abuse This number tells you the total load capacity of your floor. How do … For example, a floor joist at 16” spacing’s that can carry 53 pounds per linear foot would translate into a 318 pound single point load at its center. Three types of load are considered while designing slab: Besides, how much weight can 6 inches of concrete? The floor load in smaller office buildings can vary, and should be checked based on the demands of the occupant. Deformations (i.e. How Much Weight Can a Raised Access Floor Hold? Floor finish load Dead Load: Self weight of the slab= Mass / Weight of the slab i.e. A common bag of concrete, for example, may have a compression strength of 4,000 psi, based on a thickness of 2 inches after it has set for 28 days. We have provided a volume calculator for your convenience. Slabs, Square Footings, or Walls Floor Loading is: (machine weight + (15 lb/ft2 x 0.5 svc clear) + (10 lb/ft2 x total area))/ total area The floor loading should not exceed 240 kg/m2(50 lb/ft2) … The weight of concrete is approximately 150 pounds per cubic foot, or 4,050 pounds per cubic yard.

We have seen situations where a 6" thick slab was in place, but the capacity was rated at just 10,000 pounds due to the proximity of the water table to the surface. Load transfer at the control and construction joints. The formula for calculating the weight of concrete is: Length (in feet) x Width (in feet) x Thickness (in inches) /12 x 150 = weight (in pounds). Historically, most raised floors were constructed out of concrete-filled steel -shelled floor tiles. Please read AddThis Privacy for more information. It also matters how much the soil underneath the slab will compress. Under the heading "Concrete" you will see a specific note of the pounds per square inch--psi--strength that the concrete must reach. Formworks or molds are considerably important for building constrictions by holding fresh concrete mixture at place until it get required strength by which the self weight can be sustained. This is a terrific concrete slab calculator for estimating how many cubic yards to order to complete your concrete slabs, concrete floors, concrete walls, and concrete footings.
