Question

In a singly reinforced concrete beam section, maximum compressive stress in concrete and tensile stress reach their permissible stresses simultaneously. What is such a section called?

• A. Under-reinforced section
• B. Economic sectio
• C. Balanced section
• D. Over-reinforced section

Answer 1

The correct option is C Balanced section

(c)
In balanced failure simultaneous initiation of crushing of concrete and yielding of steel occurs as compressive strain in concrete at extreme fibre reaches ultimate strain and tensile strain at level of steel reaches yield strain
