Question

When welds are subjected to compressive or tensile or shear force alone, the stress in weld is given by :

(a) P/ttlw

(b) Ptt/lw

(c) Pttlw

(d) Plw/tt

The question was posed to me in class test.

My enquiry is from Design of Welds topic in division Welded Connections of Design of Steel Structures

Answer 1

Correct choice is (a) P/ttlw

The explanation: When welds are subjected to compressive or tensile or shear force alone, the stress in weld is given by q = P/ttlw , where q=shear stress in N/mm^2, P = force transmitted, tt = effective throat thickness of weld in mm, lw = effective length of weld in mm.
