Question

Spacing of tacking fasteners when exposed to weather should not exceed ______

(a) 32t, where t= thickness of outside plate

(b) 25t, where t= thickness of outside plate

(c) 20t, where t= thickness of outside plate

(d) 16t, where t= thickness of outside plate

I had been asked this question in an online quiz.

This is a very interesting question from Bolted Connections topic in chapter Bolted Connections of Design of Steel Structures

Answer 1

Correct answer is (d) 16t, where t= thickness of outside plate

Easiest explanation: Spacing of tacking fasteners in a line should not exceed (i)32t or 300mm, whichever is less when not exposed to weather, where t= thickness of outside plate, (ii)16t or 200mm, whichever is less when not exposed to weather, where t= thickness of outside plate.
