Abstract: This paper emphasizes structural analysis of post using finite element analysis and theoretical models. For small size post, an axially symmetric model is utilized to analyze stress distribution in the post and sheath, where applicable. Analyses are directed towards obtaining the distribution of confining pressure on coal ash based grout due to sheathing material. Buckling of big size post is also studied. An extensive laboratory testing is conducted to obtain engineering properties of coal ash based post and crib members. Full scale buckling testing of coal ash based post is also carried out to compare results obtain from testing of timber support.
