Reliability of silo structure with geometric imperfections [PDF]
PAMM, 2009 AbstractReliability of a silo structure with geometric imperfections is estimated. As the silo cylindrical constructions can be loaded with pressure below the atmospheric any geometric discrepancies are very dangerous and can significantly reduce their capacities. A probabilistic approach was applied. Two cases were considered.
