What is Depth of Equivalent Rectangular Compressive Stress Distribution?

Generally, the Evaluation of Flexural Strength is calculated by parabolic stress distribution. For more simpler approach, in 1930s, Whitney proposed an equivalent rectangular stress distribution to replace the original. In that distribution, average 0.85fc', (0.85* characteristic compressive strength), is used with a rectangle of depth a, which is termed as depth of equivalent rectangular tress distribution.

How to Calculate Depth of Equivalent Rectangular Compressive Stress Distribution?

Depth of Equivalent Rectangular Compressive Stress Distribution calculator uses Depth of Rectangular Stress Distribution=((Area of steel required-Area of compression reinforcement)*yield strength of reinforcement)/(28 Day Compressive Strength of Concrete*Beam Width) to calculate the Depth of Rectangular Stress Distribution, The Depth of Equivalent Rectangular Compressive Stress Distribution formula is defined by the parameters area of tension reinforcement, area of compression reinforcement, compressive strength of concrete and width of beam section. Depth of Rectangular Stress Distribution and is denoted by a symbol.

How to calculate Depth of Equivalent Rectangular Compressive Stress Distribution using this online calculator? To use this online calculator for Depth of Equivalent Rectangular Compressive Stress Distribution, enter Area of steel required (As), Area of compression reinforcement (As'), yield strength of reinforcement (fy, 28 Day Compressive Strength of Concrete (fc) and Beam Width (b) and hit the calculate button. Here is how the Depth of Equivalent Rectangular Compressive Stress Distribution calculation can be explained with given input values -> 0 = ((0.0001-0.0001)*10000000)/(100000000*0.01).

FAQ

What is Depth of Equivalent Rectangular Compressive Stress Distribution?
The Depth of Equivalent Rectangular Compressive Stress Distribution formula is defined by the parameters area of tension reinforcement, area of compression reinforcement, compressive strength of concrete and width of beam section and is represented as a=((As-As')*fyc*b) or Depth of Rectangular Stress Distribution=((Area of steel required-Area of compression reinforcement)*yield strength of reinforcement)/(28 Day Compressive Strength of Concrete*Beam Width). Area of steel required is the amount of steel required for resisting the shear or diagonal stress as stirrups. , Area of compression reinforcement is the amount of steel required in the compression zone, Yield strength of reinforcement is stress at which a predetermined amount of permanent deformation occurs, 28 Day Compressive Strength of Concrete is defined as the strength of the concrete after 28 days of using it and Beam Width is defined as the shortest/least measurement of the beam.
How to calculate Depth of Equivalent Rectangular Compressive Stress Distribution?
