Braced Length & Column Buckling

To investigate the concept of braced length and buckling.

Definition and Theory
It is important to understand how to reduce the amount of buckling in a long continuous column by laterally bracing it. A long continuous column braced in the middle is more economical and usually stronger than the sum of two shorter columns with the same braced length. Joining two columns together is expensive and creates a weak connection point. This is why most structures try to use long continuous columns instead of many shorter columns of the same length. This experiment will give a conceptual understanding of how a long column behaves when it is braced at different points.
