Maximum Slab thickness Solution

Follow our step by step solution on how to calculate Maximum Slab thickness?

FIRST Step Consider the formula
h=(ln36)(0.8+fysteel200000)
Next Step Substitute values of Variables
h=(101mm36)(0.8+250MPa200000)
Next Step Convert Units
h=(0.101m36)(0.8+2.5E+8Pa200000)
Next Step Prepare to Evaluate
h=(0.10136)(0.8+2.5E+8200000)
Next Step Evaluate
h=3.50918888888889m
Next Step Convert to Output's Unit
h=3509.18888888889mm
LAST Step Rounding Answer
h=3509.1889mm

How to Evaluate Maximum Slab thickness?

Maximum Slab thickness evaluator uses Maximum Slab Thickness = (Length of Clear Span in Long Direction/36)*(0.8+Yield Strength of Steel/200000) to evaluate 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 evaluate Maximum Slab thickness using this online evaluator? To use this online evaluator for Maximum Slab thickness, enter Length of Clear Span in Long Direction (ln) & Yield Strength of Steel (fysteel) and hit the calculate button.

FAQs on Maximum Slab thickness

What is the formula to find Maximum Slab thickness?
The formula of Maximum Slab thickness is expressed as Maximum Slab Thickness = (Length of Clear Span in Long Direction/36)*(0.8+Yield Strength of Steel/200000). Here is an example- 3.5E+6 = (0.101/36)*(0.8+250000000/200000).
How to calculate Maximum Slab thickness?
With Length of Clear Span in Long Direction (ln) & Yield Strength of Steel (fysteel) we can find Maximum Slab thickness using the formula - Maximum Slab Thickness = (Length of Clear Span in Long Direction/36)*(0.8+Yield Strength of Steel/200000).
Can the Maximum Slab thickness be negative?
No, the Maximum Slab thickness, measured in Length cannot be negative.
Which unit is used to measure Maximum Slab thickness?
Maximum Slab thickness is usually measured using the Millimeter[mm] for Length. Meter[mm], Kilometer[mm], Decimeter[mm] are the few other units in which Maximum Slab thickness can be measured.
