What is a column in a building?
Column is basically a vertical structure, which helps to transfer the load from top to bottom in a framed structure. Specifically columns transfer the compressive load from top floors, ceiling or beam to the foundation or to the beams. The cross section of the column is mostly rectangular , square or circular. Sometimes we modify these shape to meet the aesthetics of the building. The first step is to know the dimension (length and breadth) of the member. In the case of a column it is basically the height and the lateral dimension of the member.
What is effective length?
Effective length (l eff) of column is a parameter which is related to the load carrying capacity of the column member. It is not necessary that effective length and the actual physical length of column will be equal in magnitude. The value of effective length varies as per the type of support of the column. As per IS 456: 2000, the effective length is related to the unsupported length by some factor. The relation is as follows:
