Question

Lap length of reinforcement in compression shall not be less than

Where $\varphi$ = diameter of bar.

• A. $30\varphi$
• B. $24\varphi$
• C. $20\varphi$
• D. $15\varphi$

Answer 1

The correct option is B $24\varphi$

(b)
Lap length in compression shall not be less than $24\varphi$
Lap length in flexural tension shall be greater of $L_d$ or $30\varphi$
Lap length in direct tension shall be greater of $2L_{d}or30\varphi$.
where $L_d$ is the development length.
