Abstract:Spiral steel silo, as a kind of modern special storage structure, is widely used in cement, grain and other industries because of its characteristics of low material consumption, high ring tension strength, large radial pressure and no leakage. In actual use, various factors have caused accidents such as cracking, collapse, and tilting of the silo. Through the on-site test of the tilting accident of a spiral steel silo, combined with the test of the structural strength, reinforcement arrangement, section size, structural connection, installation deviation, crack, damage and mechanical properties of the actual material, the finite element calculation results under different load conditions were analyzed to determine the main cause of the accident and advice and suggestions were given.

Keywords:spiral steel silo; test; ABAQUS; finite element analysis; appraisal
