In discussing the analysis and design of various structures in the previous chapters, we had
two primary concerns: (1) the strength of the structure, i.e. its ability to support a specified
load without experiencing excessive stresses; (2) the ability of the structure to support a
specified load without undergoing unacceptable deformations. In this chapter, we shall be
concerned with stability of the structure, i.e. with its ability to support a given load without
experiencing a sudden change in its configuration. Our discussion will relate mainly to
column, i.e. to the analysis and design of vertical prismatic members supporting axial loads.
If a beam element is under a compressive load and its length if the orders of magnitude are
larger than either of its other dimensions such a beam is called a columns. Due to its size its
axial displacement is going to be very small compared to its lateral deflection called buckling.
Quite often the buckling of column can lead to sudden and dramatic failure. And as a result,
special attention must be given to design of column so that they can safely support the loads.
In looking at columns under this type of loading we are only going to look at three different
types of supports: pin-ended, doubly built-in and cantilever.
