Q: Based on the slenderness ratio, a steel column is found to be an intermediate column. The failure of such a column is visible as:
  • A. The steel column will not fail but remain unstable.
  • B. a mixed mode of buckling and crushing
  • C. only buckling
  • D. only crushing
Correct Answer: Option B - Euler's equations are valid for long columns. There are many situations in which columns may not be treated as long column and may be of very short or intermediate in nature. Very short columns are failed by crushing, whereas intermediate columns are failed by combinations of crushing and buckling.
B. Euler's equations are valid for long columns. There are many situations in which columns may not be treated as long column and may be of very short or intermediate in nature.
