What is the difference between axial and bending loads in structural engineering?

Axial and bending loads are both types of loads that affect structures, but they act on different planes.

Axial loads act through the center of gravity of a structure and apply a force parallel to its axis. This type of load creates tension or compression forces in the structure. Examples of axial loads include the weight of columns, vertical loads, or the force of tension in a cable.

Bending loads act on a structure perpendicularly to its longitudinal axis, causing it to bend or deflect. Bending loads create both tensile and compressive forces on different parts of the structure. Examples of bending loads include the wind on a tall building or a beam supporting a heavy weight.

In summary, axial loads act on a structure along its lengthwise axis, while bending loads act on a structure across its lengthwise axis.
