(a) increase in ductility reduces strength of member

(b) reduction in ductility increases strength of member

(c) increase in ductility does not affect strength of member

(d) reduction in ductility reduces strength of member

I have been asked this question in an international level competition.

I need to ask this question from Angles Under Tension and Factors affecting Strength topic in portion Design of Tension Members of Design of Steel Structures

Answer 1

Right choice is (d) reduction in ductility reduces strength of member

To explain: Reduction in ductility tends to reduce strength of member. An increase in ductility tends to increase net section strength by allowing better plastic redistribution of stress concentration over cross section.
