The article comprehensively discusses an innovative metal sheet structure - a
spiral fold silo: its features, operation under load, and reliability. The stress-strain state of interfold zone of a spiral-fold silo is considered. The calculations of the stress-strain state of the silo were compared with the analytical calculations by the software package LIRA-SAPR. The work the midsection of the shell segment (zone between folded locks) of the spiral-fold silo was experimentally verified. Considering the results of the studies of the stress-strain state of this metal silos, a methodology for reliability analysis based on the analysis of the strength reserve was developed. The obtained results of calculations confirmed the high reliability of metal spiral-fold silos.
