Measurement of strain and determination of stress state using a multi-chamber vertical cylindrical tank model

Abstract Designing a new construction of large-volume multi-chamber tanks or converting existing single-chamber into for storage various types petroleum products is very demanding and responsible job, from the aspect strain-stress analysis need to ensure structural integrity. From wide range conducted theoretical experimental-numerical research, this paper singles out applied method similarity mechanics. The research was performed on model four-chamber tank with dimensions reduced by 20 times (1:20) in relation real tank, made steel sheets quality S.0361. During cold-water pressure test (hydro test), change strain stress state monitored zones that were defined as critical preliminary numerical finite element (FEM). results these measurements, along other reliable methods, can be useful design 5.000 m3 volume.
