1.	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/γm1The 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» 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.
