The length of member should be _________ for a short column(a) L ≤ 8

1.	The length of member should be _________ for a short column(a) L ≤ 88.5r(b) L ≥ 88.5r(c) L ≥ 125r(d) L > 150rI had been asked this question by my school principal while I was bunking the class.This is a very interesting question from Behaviour of Compression Members & Types of Sections topic in portion Design of Compression Members of Design of Steel Structures
Answer» Right option is (a) L ≤ 88.5r The best I can explain: For a MEMBER to be CLASSIFIED as short column, length of member should be L ≤ 88.5r , where r is RADIUS of gyration. The SLENDERNESS RATIO of column defines the column as short or long column.
