Civil Engineering MCQAE Level Civil Engineering
In a spiral reinforced column as per IS 456, the spiral reinforcement must be designed so that its contribution to load capacity equals:
RCCSpiral ColumnMEDIUM
Choose the correct answer
A
The capacity of the additional concrete outside the core
B
The load in the longitudinal steel
C
2% of total column load
D
The punching shear capacity
Correct Answer
A. The capacity of the additional concrete outside the core
Why is this the answer?
IS 456:2000 Cl. 26.5.3.2(d): The strength provided by spiral steel shall be at least 1.5 times the strength of the concrete displaced by the spiral steel (i.e., the shell concrete outside the core that tends to spall off).
