Question

The design tensile strength of tensile member is

(a) minimum of strength due to gross yielding, net section rupture, block shear

(b) maximum of strength due to gross yielding, net section rupture, block shear

(c) strength due to gross yielding

(d) strength due to block shear

This question was posed to me in an internship interview.

This interesting question is from Behavior and Design Strength of Tension Members topic in portion Design of Tension Members of Design of Steel Structures

Answer 1

Correct option is (a) minimum of strength due to gross yielding, net section rupture, block shear

The best explanation: The design tensile strength of tensile member is taken as the minimum of strength due to gross yielding (Tdg=fyAg/1.1), net section rupture(Tdn=0.9Anfy/γm1), block shear (Tdb1=(Avgfy/√3 γm0)+(0.9Atnfu/γm1),  Tdb2=(Atgfy/ γm0)+(0.9Avnfu/√3 γm1)).
