Steel Structure Design - Engineering

Q1:

The equivalent axial tensile load Pe, which produces an average axial tensile stress in the section equivalent to the combined stress due to axial tension P and bending M, at the extreme fibre of the section, is given by (where Z is the section modulus of the section).

D <img src="/_files/images/civil-engineering/steel-structure-design/102-14-117-4.png">

ANS:A -

Given Answer is right.

The first component is due to the direct load.

The second one is due to bending compression.
