Lade, and Ghaboussi and Momen theories for cohesionless granular elasto-plastic media are considered as candidate models for predicting thermally induced pressures in grain bin walls. An axisymmetric finite element model for the fill material was developed using the Lade theory; whereas, the bin wall was modeled using the thin shell approach. The finite element model results were compared against the measured bin wall stresses under static load and falling ambient temperatures conditions. The predicted values agreed very well with the measured thermally induced pressures.
