To analyze the structure strength of 30 m-diameter welded steel siloSilo, steel for fly ash storage in Jingdezhen city, the mechanical model and stiffener optimization of the siloSilo is studied. A systematical finite element model incorporating static storage loads and gravity loads is established for analyzing the stress distribution under static storage conditions, and the result reveals that the maximum stress occurs between the bottom connection pieces of annular steelSteel, accounting for only 17.4% of the yield strength. The longitudinal stiffeners reduce stress concentration significantly, which leads to the stress distribution more uniform. With the synergistic effect between circumferential and longitudinal stiffeners, the stress of the siloSilo reduces by 13.78%.
