Question

The design strength of tension member corresponding to net section rupture is given by :

(a) Anfyγm1

(b) 0.9Anfyγm1

(c) 0.9An/fyγm1

(d) 0.9Anfy/γm1

The question was asked by my college director while I was bunking the class.

The doubt is from Behavior and Design Strength of Tension Members topic in chapter Design of Tension Members of Design of Steel Structures

Answer 1

Right choice is (d) 0.9Anfy/γm1

The explanation: The design strength of tension member corresponding to net section rupture is given by Tdn = 0.9Anfy/γm1,  where An = net effective area of cross section in mm^2, fy = ultimate strength of material in MPa, γm1 = partial safety factor for failure due to rupture of cross section = 1.25.
