Wall Pressures in Squat Steel Silos from Simple Finite Element Analysis

摘要

Many different procedures for predicting the pressures on circular silo walls have been developed. These include methods based on simple assumptions, methods based on plasticity theory, methods based on minimizing the stored solid recoverable strain energy and some finite element procedures using complex non-linear material characterization. The purpose of the present paper is to show that comparatively simple finite element techniques which include appropriate wall friction characteristics can accurately model the pressures exerted by stored solids on cylindrical silo walls, at least for the initial filling condition.
