Etabs unbraced length
WebThe slenderness ratio (ratio of effective length to the least lateral dimension) is less than 12 in the short reinforced column. Short columns fail due to crushing or yielding of the steel bars. The loads that a short column may support depend on the dimension of cross-section and the strength of materials. Short columns show a little flexibility.
