Abstract

Abstract: The distribution of vertical stress for both active and passive state in the silo with a
central innerdowncomer is reported in this paper. Experimental measurement of the axial
distribution of vertical stress for bothactive and passive state in the silo are in good
agreement with that predicted by theoretical analysis. The meanaxial stress is reduced due
to the presence of the inner downcomer in the silo.

Key words: silo, inner downcomer, vertical stress distribution
