Maximum Slab thickness Solution

STEP 0: Pre-Calculation Summary

Formula Used

Maximum Slab Thickness = (Length of Clear Span in Long Direction/36)*(0.8+Yield Strength of Steel/200000)
h = (l_n/36)*(0.8+fy_steel/200000)
This formula uses 3 Variables

Variables Used

Maximum Slab Thickness - (Measured in Meter) - Maximum Slab Thickness, Thickness of concrete slab depends on loads and size of the slab.
Length of Clear Span in Long Direction - (Measured in Meter) - Length of Clear Span in long direction, The clear unobstructed distance between the inner extremities of the two supports of a beam.
Yield Strength of Steel - (Measured in Pascal) - Yield Strength of Steel is the level of stress that corresponds to the yield point.

STEP 1: Convert Input(s) to Base Unit

Length of Clear Span in Long Direction: 101 Millimeter --> 0.101 Meter (Check conversion here)
Yield Strength of Steel: 250 Megapascal --> 250000000 Pascal (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

h = (l_n/36)*(0.8+fy_steel/200000) --> (0.101/36)*(0.8+250000000/200000)

Evaluating ... ...

h = 3.50918888888889

STEP 3: Convert Result to Output's Unit

3.50918888888889 Meter -->3509.18888888889 Millimeter (Check conversion here)

FINAL ANSWER

3509.18888888889 ≈ 3509.189 Millimeter <-- Maximum Slab Thickness

What is the Standard Concrete Floor Slab Thickness in Residential Construction?

Standard concrete floor slab thickness in residential construction is 4 inches. Five to six inches is recommended if the concrete will receive occasional heavy loads.

What is the Minimum Thickness of a Slab?

The minimum thickness of a slab is not less than 4 inch according to the standard. But, the thickness is mostly depends upon the design load and the span.

How to Calculate Maximum Slab thickness?

Maximum Slab thickness calculator uses Maximum Slab Thickness = (Length of Clear Span in Long Direction/36)*(0.8+Yield Strength of Steel/200000) to calculate the Maximum Slab Thickness, The Maximum slab thickness is defined as the parameters of length of clear span in long direction, in (mm) and yield strength of reinforcement, (MPa). The equation above is used as per ACI code. Maximum Slab Thickness is denoted by h symbol.

How to calculate Maximum Slab thickness using this online calculator? To use this online calculator for Maximum Slab thickness, enter Length of Clear Span in Long Direction (l_n) & Yield Strength of Steel (fy_steel) and hit the calculate button. Here is how the Maximum Slab thickness calculation can be explained with given input values -> 3.5E+6 = (0.101/36)*(0.8+250000000/200000).

FAQ

What is Maximum Slab thickness?

The Maximum slab thickness is defined as the parameters of length of clear span in long direction, in (mm) and yield strength of reinforcement, (MPa). The equation above is used as per ACI code and is represented as h = (l_n/36)*(0.8+fy_steel/200000) or Maximum Slab Thickness = (Length of Clear Span in Long Direction/36)*(0.8+Yield Strength of Steel/200000). Length of Clear Span in long direction, The clear unobstructed distance between the inner extremities of the two supports of a beam & Yield Strength of Steel is the level of stress that corresponds to the yield point.

How to calculate Maximum Slab thickness?
