Que 1: Name the RCC code and Steel code and when they were revised last ?
Ans: Latest RCC code is IS: 456-2000 & latest steel code is IS:800-2007 (Revised as per limit state method).
Que 2: Define Under-reinforced section, Balanced and over-reinforced Section ?
Ans: Under-reinforced Section : The steel reinforcement reaches the yield strain at stresses lower than the stress at which the concrete fails.
Balanced-reinforced Section : The tensile steel reaches the yield strain while the concrete reaches failure strain in bending.
Over-reinforced Section : In which the concrete reaches its collapse strain earlier than the steel reaches its yield strain.
