1. Purpose
(1) To study buckling of column and to understand the importance of
buckling.
(2) To examine the critical loads for the different end conditions and compare the critical loads with the theoretical values.
(3) To compare and analyze the changes in the different materials.
2. Theory & Assumption
(1) The phenomenon of Buckling
A structure may fail to support its load when; a connection snaps, or it bends until it is useless, or a member in tension either pulls apart or a crack forms that divides it, or a member in compression crushes and crumbles, or, finally, if a member in compression buckles, that is, moves laterally and shortens under a load it can no longer support. Of all of these modes of failure, buckling is probably the most common and most catastrophic.
What is buckling?
If a compression member is relatively slender, it may deflect laterally and fail by bending rather than failing by direct compression of the material. When lateral bending occurs, we say that the column has buckled. Under an increasing axial load, the lateral deflections will increase too, and eventually the column will collapse completely.
The phenomenon of buckling is not limited to columns. Buckling can occur
