Columns subjected to uniaxial compression fail due to lateral tensile stresses caused by Poisson effect resulting in lateral expansion, as shown in Fig. 2.1a. Poisson effect describes the expansion or contraction of a material in directions perpendicular to the direction of loading. If lateral expansion can develop freely, then the member is in uniaxial stress state. The resulting cracks are splitting tensile cracks parallel to the direction of loadings. This type of failure is usually observed for uniaxially loaded columns with low or normal compressive strength.
