Finite Element Analysis Of Wind Pressure And Structure Of Steel Silo Under Strong Wind

Because of the advantages of economy,high strength,standardization,convenient construction,low cost and easy to be constracted,steel silos are widely used in industrial and agricultural production of liquid and bulk storage.As the steel silo dimensions become larger,steel silo structure is easy to lose stability and destruct under strong wind.Therefore,it is very important to analyze the wind pressure and structural strength of steel silo under strong wind.Firstly,the Realizable k-? turbulent model and SIMPLEC algorithm are used to simulate the wind field around the steel silo in Zhanjiang Port by the fluid dynamics software Fluent.The wind pressure on the surface of the steel silo distribution,and the effect of the silo canyon on the impact of steel silo pressure are analyzed.The coefficient of wind load shape of steel silo under four kinds of arrangement of single silo,three silos,four silos and five silos is obtained based on the numerical simulation results.The results show the the law of wind load shape factor of the steel silo.Secondly,the stress and displacement of steel silo under the action of gravity,wind load,grain load and other load are analyzed through the establishment of three-dimensional finite element model of steel silo structure in Zhanjiang Port.This paper analyzes the stress and displacement of the steel silo under empty load,half load and full load in Zhanjiang Port and summarizes the distribution of stress and displacement.Finally,the causes of the failure of the steel silo in Zhanjiang Port under strong wind are summarized through the comprehensive analysis of the results of wind pressure and structure analysis.
