The neutral axis is the line where the stress is zero in a reinforced concrete structure.
The neutral axis divides the cross-section of the structure into two parts: the compression zone and the tension zone.
The depth of the neutral axis depends on the moment of resistance of the section and the bending moment applied.
The position of the neutral axis affects the amount of reinforcement required in the tension zone.
The n...
