Question

Difference between axially loaded column and eccentrically loaded column

Answer 1

Eccentric loading on column

When the load acting on the column is offset from the centroid of the column, then it establishes the bending of column along with the axial stress. This offset loading of the column is referred as eccentric loading.

Eccentric loading will not be at the middle of cross-section of the column. It will be at some distance from the middle of the column either towards right or left corners of the column. The distance between the middle of cross-section of the column and the eccentric load is referred as eccentricity symbolized by e.

Increase in the eccentric load increases the axial load and the moment acting on the column. This makes the column to bend additional increasing the bending of column.

Answer 2

Difference between the axially loaded column and eccentrically loaded column:

Eccentrically loaded column:

• The load which acts on the column is 'offset from the centroid' of the column, then it creates the bending of the column along with the 'axial stress'. This offset 'loading' of the column is called as eccentric loading.
• The eccentric loading column will not at the cross-section of the column.

Axially loaded column:

• When the load is acted on the longitude axis of the column is called Axial loading of the column.  
• It is transferred to axially. Axial load is the comprehensive load.
