Which of the following factors is included in the limit state of strength?(a) Fire(b) Failure by excessive deformation(c) Corrosion(d) Repairable damage or crack due to fatigueI got this question during an internship interview.I want to ask this question from Limit State Method in section Basics of Structural Design of Design of Steel Structures

Answer»

Correct answer is (b) Failure by EXCESSIVE deformation

To explain: Limit state of strength are prescribed to avoid collapse of structure which MAY endanger safety of LIFE and property. It INCLUDES (i) loss of equilibrium of whole or part of structure, (II) loss of stability of structure as a whole or part of structure, (iii) failure by excessive deformation, (iv) fracture due to fatigue , (v) brittle fracture.
