Abstract

The large enamel-assembled storage silo, as an emerging industry, is currently in a period of rapid development. Its unique bolted construction technology and excellent enamel anti-corrosion technology have led to the gradual application of enamel-assembled silos in areas such as military storage, strategic material reserves, municipal wastewater treatment, and biogas fermentation. As a new type of silo, the stable structure and the high economic efficiency are the key factors ensuring its explosive growth in applications. This paper aims to comprehensively evaluate the structural performance of material silos under varying load conditions and verify their safety to ensure the robustness and reliability of the design. The SAP2000 simulation software is employed for the analysis, simulating the stress states of the material silos under static conditions, constant load + storage load + seismic conditions, and constant load + wind load conditions. Through multiple load combinations, the stress states of the material silos under various conditions are validated. Under static conditions, the maximum stress occurs at the bottom wall plate of the silo wall, reaching 84.8 MPa, showing consistency throughout the entire structure and presenting an axial increasing trend. Regarding displacement characteristics, the most significant stress concentration and deformation occur in the area of the silo structure which is subjected to the load. Under constant load + storage load + seismic conditions, the overall stress of the silo wall decreases non-linearly from the bottom fixed constraint, with stress fluctuations occurring at the cement-poured fixed constraint, which is the position of the maximum static water pressure force. Under constant load + wind load conditions, the vertical stress values of the silo structure are uniformly distributed, with differences in circumferential stress distribution—compression on the windward side and tension on the leeward side, reaching up to 100 MPa, with deformation decreasing from top to bottom. Considering material load, wind load, seismic load, and other possible conditions, this paper concludes the stress and strain conditions of the material silo under different working conditions, which helps optimize and improve the structure of existing material silos and promote the development of related fields.
