Amount of Reinforcement
Amount of Reinforcement
(OP)
While determining the Rho= Rebar Area / b*d at any given section, do we include sum of both tensile and compressive steel areas to calculate Rho or the equation should only consider the reinforcement for either positive or negative moment while satisfying the section for Rho max and Rho min values?
I typically take sum of areas for both tensile and compressive rebar, just trying to think out loud.

As is the area of tension steel. You don't add both the tension and compression steel together.

But that's me.

Reinforcement ratio is an extrememly basic, yet crucial, concept.

The threads you referenced were about the commingling of the code requirement for flexural reinforcement vs. direct tension shrinkage and temperature reinforcement. Shrinkage reinforcement is based on the gross area of the concrete, and can be placed throughout the section. It is clear in the current thread that the OP is asking about flexural reinforcement, and JAE has given the correct answer...the required amount of flexural reinforcement must be on the tension side.
