Overall Structure Finite Element Numerical Simulation Of Long-span Steel Approach Bridge And Trestle Bridge Of Floating Dock

For production Conveniently,rivers in mountain areas with large water levels,the type of floating dock is always used in liquefied petroleum dock.In this paper, taking Luzhou oil depot Wharf engineering design as the basis, summarized the common structure of floating dock project,the main part of the floating dock.Moving steel bridge approach uses parallel chord truss structure, trestle bridge uses fixed column structure in this engineering.After detailed introduce the basic theory of finite element and design drawings, using the finite element software to analyze the project, to achieve more reasonable design for the floating dock, it will provides some reference to this kind of engineering structure design. The specific work is as follows:â‘  Using civil engineering finite element software Midas / civil to establish beam model of steel bridge, researches based on defined unit types and constant,applied loads and boundary conditions for moving steel bridge.According to the stress and strain to determine the security and reliability of the moving steel bridge on three conditions and load combinations. While at the same load, working conditions,changing steel bridge structure type, maintain the same deflection, analyze the mechanical properties of fasting arch truss steel bridge.â‘¡ In order to determine the safe use of fixed trestle structure on the conditions of high-level and low-level.Considering the role of bank soil on the pile,adopting ABAQUS finite element software to establish the solid model of trestle bridge to research the static characteristics of fixed trestle on two kinds of conditions.According to the stress and strain results of the fixed trestle structure are obtained,the strength of total structure was assessed.â‘¢ On the basis of finite element model to investigate the dynamic characteristics of fixed trestle structure.According to the basic theory of the modal analysis and the vibration characteristicsof structure to study the stiffness distribution of fixed trestle structure.
