This paper introduces a finite element solution for predicting the normal pressure on large diameter squat silo wall, with the application of contact element and nonlinear model. The finite element analysis (FEA) described in this paper is compared with the full-scale tests and Coulomb theory and the Chinese Code. The predicted results are in good agreement with Coulomb theory, when the top of the stored solid is horizontal; while the result of Coulomb theory is much larger than the other solutions, when the top of the stored solid is a conical surcharge pile. The results from the modified Rankine theory in Chinese Code are acceptable in both conditions. Finally, the effects on the normal pressure of Young′s Modulus are also discussed.
