Explanation

For a singly reinforced rectangular balanced section with permissible tensile stress in steel of 140 N/mm², the neutral axis depth is approximately 0.40 times the effective depth (d). This value is derived from the balance of steel and concrete stresses and is not influenced by the concrete grade alone.
