Question

As per IS800-2007, the minimum centre-to-centre bolt spacing measured in the direction of stress is ……. , where \( d \) is the nominal diameter of bolt.

• A. \( 1.5 d \)
• B. \( 2.0 d \)
• C. \( 2.5 d \)
• D. \( 3.0 d \)

Hint:

- Proper bolt spacing is critical in preventing tearing failures and ensuring effective load transfer in bolted connections.

Answer 1

The Correct Option is C

Step 1: Understanding bolt spacing in steel structures. 
- As per IS 800:2007, the minimum bolt spacing in the direction of stress should be at least \( 2.5 d \), where \( d \) is the nominal diameter of the bolt. 
Step 2: Reason for spacing requirement. - Ensuring sufficient spacing prevents overlapping stress zones in the steel plate. - It reduces the risk of shear failure and improves load distribution. Thus, the correct answer is (C) \( 2.5 d \).
