In which beam tension capacity of steel is greater than combined compression capacity of steel and concrete?(a) Over-reinforced(b) Under-reinforced(c) Singly reinforced(d) Doubly reinforcedThis question was posed to me in an international level competition.I want to ask this question from RCC, PSC and Ferro-Cement topic in portion Building Construction of Basic Civil Engineering

Answer»

Correct choice is (a) Over-reinforced

To elaborate: Over-reinforced BEAMS have HIGHER TENSION capacity. So, these beams FAIL by crushing of compression zone concrete, WITHOUT any warning.
