2022. 10. 12. · Concrete columns are used worldwide in all types of concrete frame structures. RCC concrete columns are of two types based on the height of the column and cross-section.

The first case is a trivial case, it corresponds to no deflection, and therefore no buckling – it describes the case when the axially applied load simply compresses the beam in the x direction. For beam buckling, we're interested in the second case, i.e. cos(kL)=0. Cosine is a periodic function, and we know that cos(x)=0 at intervals of pi/2, 3pi/2, etc.
