Civil Engineering MCQAE Level Civil Engineering
As per IS 456:2000, the lap length for deformed bars in tension zones in an RCC beam (for full development length) is generally taken as:
RCCLap Splice LengthMEDIUM
Choose the correct answer
A
L_d
B
1.3 L_d
C
2 L_d
D
0.5 L_d
Correct Answer
B. 1.3 L_d
Why is this the answer?
IS 456 Cl. 26.2.5.1: Lap splices shall not be less than the development length (L_d) in compression and 1.3 L_d in tension. Laps in tension are longer to account for higher stress transfer demands.
