Application And Analysis Of Great-span Rectangle Steel Tube Monolayer Sphere-shell Structure

Great-span interspace structure is the quickest development structure presently.Great-span construction and its core interspace structure technology development statusare the most importance symbol of nation constuction science and technology level.Great-span interspace sphere-shell structure is the bend-surface type of griddingstructure, it have pole and shell inherence characteristic. have characteristic of the powerin reason, cover with great span, great firm tolerance, light self-respect, sculpt richnessand beauty, integrate technic economy target characteristic, is the mostly structure formof great-span and great-space, have amplitude develop foreground. The great-spanrectangle steel tube monolayer sphere-shell structure have the weak thickness, andvirtue of concision open-penetrate and save on invest.The sphere project of International meeting-center, adopt rectangle steel tube eform.builded the separate 50m and 38m diameter steel structure glass-curtainsphere. The stability analysis of this great-space monolayer sphere-shell structur, is pivotand nodus of the project. The thesis adhibit investigate method of advanced theoreticsanalysis soft, and model experiment of reduced scale model, to analysis and study the50m diameter rectangle steel monolayer sphere-shell steel structure glass-curtainsphere, indicate the importance effect of the structure geometry non-linearity on theinteger stabilityFor the sake of Confirm the reliability of theoretics analysis and calculational, putup a series of reduced scale model simulate load test at structure and defend disastergraduate school tongji university. Researched the degree of structure geometrynon-linearity through the test, in order to affirm veracity of structure analysis.The testindicate frame of the model all on elasticity, and the stress of test component all less thansteels design intension.The thesis count the load effect to the structure from wind-load, earthquake-load, temperature-load, branch-seat subside effect, geometry non-linearitystabilization analysis, to confirm rationality and economy of the project structure, provide reference to the same type engineering for design and actualize.
