Variations among long and short columns
This construction video tutorial demonstrates the variations among short column and long column.
SHORT COLUMN: Short column is defined as the column that contains very large lateral dimension with reference to its length or height is called as short column. Here, the proportion of effective length to its lateral dimension is under or equivalent to 12.
The proportion of effective length of a short column to its radius of gyration remains under 40 or equivalent to 40.
Bulking tendency is very poor. A column buckling analysis results in finding out the maximum load that a column can sustain prior to collapsing.
The load bearing strength is high with reference to the long column of the similar cross-sectional area.
The collapsing of short column occurs due to crushing.
LONG COLUMN: Long column is defined as the column that contains small lateral dimension with reference to its length or height. Here, the proportion of effective length of column to its lowest lateral dimension surpasses 12.
The proportion of effective length of a long column to its lowest radius of gyration surpasses 40.
Column buckling easily occurs in long and slender column.
The load bearing strength of a long column remains under with reference to short column with similar cross sectional area.
The column normally collapses in buckling.
