Question

As per IS:800-1984, the minimum pitch of rivets in a row is recommended as the diameter of the rivet times
1. 2.0
2. 2.5
3. 3.0
4. 4.0

Answer 1

Correct Answer - Option 2 : 2.5

Concept:

Minimum pitch	2.5 times of nominal diameter of the rivet
Maximum pitch for
(i) any two adjacent rivets (including tacking rivets)	32t or 300 mm, whichever is less
(ii) rivets lying in a line parallel to the force in the member. (a) in tension (b) in compression	16t or 200 mm, whichever is less 12t or 200 mm, whichever less

 

Where t = thickness of thinner outside plate.

Minimum pitch = 2.5φ

Where, φ: Nominal diameter of the rivet
