| In recent decades, silo has been chosen as the main structure in the bulk material flow due to the rapid development of logistics industry. The IBAU HAMBURG is a s pecial homogenizing silo including the inverted cone, having two clear differences co mpared with the conventional silo when designing:load calculation on the silo wall fr om the bulk material; stability analysis of the steel wall under vertical friction forces a nd horizontal pressures. So far, there is no design code for the IBAU HAMBURG, an d few relevant research references. Therefore, the in-depth theoretical study and finite element analysis to the IBAU HAMBURG is the basis for the promotion and applica tion of this kind of silo structure. In this paper, the IBAU HAMBURG in MESAIEE D harbor in Qatar was taken as the research object. Base on the classical theory, comb ined with the finite element method and related specifications, this paper conducted a series of studies on the stability bearing capacity of the IBAU HAMBURG. The main work is as follows:(1) The main components of the IBAU HAMBURG were introduced, such as the cent ral cone, ring beam, silo wall above the cone, lower part of the silo wall and silo wall below central cone, and review the research status at home and abroad of the IBAU H AMBURG.(2) Referencing to the relevant domestic and overseas codes, the vertical friction forc es and horizontal pressures were calculated on the silo wall from the bulk material. B ased on it, the stability bearing capacity of the IBAU HAMBURG was checked using specification formulas.(3) The domestic and overseas classical theory of cylindrical shell were summarized, the steel wall stability bearing capacity of the IBAU HAMBURG was analyzed under vertical friction forces and horizontal pressures.(4) The overall FEM model of the IBAU HAMBURG was established using the famo us analysis software ABAQUS. Considering the initial geometric imperfections, the s tability bearing capacity and ultimate capacity were studied under vertical friction for ces and horizontal pressures.(5) Four calculation results above were compared and the differences and reasons wer e found out. The research results in this paper will provide some theoretical references and ba sis for the future design and research of the IBAU HAMBURG. |
