Details about axial load, uniaxial and biaxial bending moments in columns

This civil engineering article focuses on the following topics :-

a. Axial Load in columns
b. Axial Load With Uniaxial Bending in columns
c. Axial load with biaxial Bending in columns

Besides, you will also learn how to determine whether the column should be designed for axial force or axial force with uniaxial bending or axial force with biaxial bending.

The definition of above terms is given below :-

Axial Load – It stands for a force that is functioning to the centroid of a specific section and perpendicular to the plane of section.

The force can be differentiated as concentric force or eccentric force as follow :-

Concentric Load – When the axial force is functioning via the centroid of the member.

Eccentric Load – When the axial does not function via the centroid of the member. Because of eccentricity, a moment will be created in any one axis of the column.

Uniaxial Bending – Here, bending occurs in any one axis of the column i.e. either in the major axis or in the minor axis.

Biaxial Bending – Here, bending occurs in both axis of the column.

In uniaxial bending, the load is eccentric about only one axis but in biaxial bending the load is eccentric about both the axis.

To get more details, go through the following video tutorial.
