Civil Engineering QUESTION #6609
Question 1
Which of the following parameters is used to categorize a steel section as 'compact' for flexure?
  • The ratio of flange width to thickness ($b/t$)✔️
  • The total depth of the beam ($d$)
  • The span-to-depth ratio ($L/d$)
  • The poisson's ratio ($\nu$)
Correct Answer Explanation
Compactness is a measure of a section's ability to develop its full plastic moment without local buckling. It is determined by checking the width-to-thickness ratios ($b/t$ for flanges, $h/t_w$ for webs) against limits $\lambda_p$.
