Question

The check for design bending strength for simply supported beams is given by

(a) Md = 2.4Zpfy/γm0

(b) Md < 1.2Zpfy/γm0

(c) Md ≤ 1.2Zpfy/γm0

(d) Md ≥ 1.2Zpfy/γm0

I got this question in an internship interview.

I'm obligated to ask this question of Design Strength of Laterally Supported Beams topic in division Design of Beams of Design of Steel Structures

Answer 1

Correct option is (c) Md ≤ 1.2Zpfy/γm0

For explanation: The check for design bending strength for simply supported beams is given by Md ≤ 1.2Zpfy/γm0 to ensure that onset of plasticity under unfactored loads is prevented.
