What and why is effective length factor used?

The concept of the effective length factors of columns has been well established and widely used by practicing engineers and plays an important role in compression member design. The effective length factor for braced columns varies from 0.5 to 1.0, whereas for unbraced columns, it can vary from 1 to infinity.

How to Calculate Effective Length Factor?

Effective Length Factor calculator uses effective length factor=Effective length/Actual unbraced length to calculate the effective length factor, The Effective Length Factor formula is defined as the ratio of effective length of column to actual unbraced length. . effective length factor and is denoted by k symbol.

Here is how the Effective Length Factor calculation can be explained with given input values -> 0.4 = 0.508000000002032/1.27000000000508.

FAQ

What is Effective Length Factor?
The Effective Length Factor formula is defined as the ratio of effective length of column to actual unbraced length. and is represented as k=l/l' or effective length factor=Effective length/Actual unbraced length. Effective length is the total length of the section. It is the length of a section which is effectively restrained. and Actual unbraced length is the distance between ends of a structural member (such as a column) which are prevented from moving normal to the axis of the member, by bracing, by floor slabs, etc.
How to calculate Effective Length Factor?
The Effective Length Factor formula is defined as the ratio of effective length of column to actual unbraced length. is calculated using effective length factor=Effective length/Actual unbraced length. To calculate Effective Length Factor, you need Effective length (l) and Actual unbraced length (l'). With our tool, you need to enter the respective value for Effective length and Actual unbraced length and hit the calculate button. You can also select the units (if any) for Input(s) and the Output as well.
