Initial-strain Analysis Of Silo-material Interaction
Modifications to a finite element program developed in a prior study were extended for an initial-strain analysis of horizontal bending moments and hoop tension developed during bisymmetrical eccentric discharge. The results obtained by the newly developed initial-strain method, by the prior study, and those required by ACI Standard 313-77, were compared for a circular concrete silo. Although a significant difference in bending moment was obtained by the initial-strain and linear analysis methods, the steel reinforcement required was nearly the same at the lower elevation. However, at the upper elevation, approximately 50% more reinforcement was required for the initial-strain analysis. The reinforcement required by ACI Standard 313-77 was comparable to that for the initial-strain method at the higher elevation, and greater for the lower elevation. © 1983.
