Free online Maximum Floor Live Load Capacity calculator. We don't collect information from our users. Online calculators and converters have been developed to make calculations easy, these calculators are great tools for mathematical, algebraic, numbers, engineering, physics problems. While cracks in a slab may not seem like a big deal, the smallest crack represents a large amount of downward pressure that may be crushing pipework beneath the slab.

1). Mr = MR*(12*t^2/6)/12000 (per 1' = 12" width), fb1(actual) = 3*P*(1+m)/(2*p*t^2)*(LN(Lr/b)+0.6159) (Ref. The SAFI CONCRETE CALCULATOR™ is used as a standalone application or in combination with the GSE CONCRETE DESIGN, part of the GSE (General Structural Engineering) software. 2. Concrete Slab Calculator for Slabs, Floors, Footings and Cylinders. 500 kg/m2 is typical for office, storage space and similar. Easy and convenient to use and of great help to students and professionals. 4.      and thus no solution for the minimum slab thickness, t(min), for one or more of the We don't save this data. For the design of an actual structure, a competent professional should be consulted.

Load capacities of simply supported concrete slabs: Imposed loads varies from approximately 1.5 kN/m2 (153 kg/m2) in domestic buildings to approximately 1 0 kN/m2 (1053 kg/m2) in heavy industrial areas. Some of our calculators and applications let you save application data to your local computer. Engineering ToolBox - Resources, Tools and Basic Information for Engineering and Design of Technical Applications! online free live maximum floor live load capacity is a great engineering tool to Assuming Slab is Reinforced for Shrinkage and Temperature Only, References: Note : Load capacities of simply supported concrete slabs: Imposed loads varies from approximately 1.5 kN/m2 (153 kg/m2) in domestic buildings to approximately 10 kN/m2 (1053 kg/m2) in heavy industrial areas.

Knowing the load-bearing capacity of your concrete is essential to make sure that what you plan to have supported by the wall or slab will not be too heavy and cause it to crack and break. 3. there will be a few situations where certain combinations of the Concentrated Disclaimer: This calculator is not intended to be used for the design of actual structures, but only for schematic (preliminary) understanding of structural design principals. Pc = Pt/Ne: Mod.       Engineering (submitted to MN/DOT, March 24, 2002) w = Maximum Allowable Stationary Live Load. Estimate any other loads (e.g.

     equations listed above. Subbase friction adjustment factor, 'C', is as follows: "Dowel Bar Opimization: Phases I and II - Final Report" - by Max L. Porter (Iowa State University, 2001) Just remember to add some extra concrete to your total order because running short is not an option. 1), bo = 4*SQRT(Ac) (assumed shear perimeter), F = 1.5 (assumed friction factor between subgrade and slab), a = 5.5x10^(-6) (assumed thermal expansion coefficient), e = 3.5x10^(-4) (assumed coefficient of shrinkage), Le = 1.0*Lr = applicable dist. Note: direct solution for t(min) has been rounded up to nearest 1/4" thickness. Radius of Stiffness, "Lr", is a measure of the stiffness of the slab relative to the foundation (subgrade). "Slab Thickness Design for Industrial Concrete Floors on Grade" (IS195.01D) - by Robert G. Packard Joint Load, Pt = lbs. 1), SSet Fb(allow) = 3*(1+m)*P/(p*(3+m)*t^2)*(LN(Ec*t^3/(100*k*a^4))+1.84-4*m/3+(1-m)/2+1.18*(1+2*m)*a/Lr) (Ref. Pt = 0.50*P (assumed load transferred across joint) Critical Dowel Load, Pc = lbs. A concrete slab is designed using normal weight concrete with f'c= 4000 psi. (Florida International University, Miami FL - Fall 2002). Add (1)+(2)+(3); 5. The Concrete Calculator allows the user to quickly and easily analyze or design reinforced concrete sections without the need to create and analyze a complete structural model (joints, members, load combinations, etc. AddThis use cookies for handling links to social media. live load for maintenance) likely to come on the concrete slab; 4. C = 0.65 for stabilized subbase Found any bugs in any of our calculators? For those cases, the user would then manually iterate the 500 kg/m2 is typical for office, storage space and similar.
