| Steel pipe truss handsome in appearance, and across a larger span much architectsfavored by many public buildings roof form of such structures. Jinan West RailwayStation roof arched truss structure for the project background, completed the followingwork:(1) Summarizes the overview of the development of the steel truss structure,characteristics and forms, arch arch axis and truss height, internode length method.(2) Jinan West Railway Station roof steel truss engineering background, according to theprinciples of the roof arch shape, Jinan West Railway Station roof truss using the archaxis of shape and space, through the comparison of plane truss and space truss form oftruss and truss section optimization; using finite element software ANSYS finite elementmodel of the Jinan West Railway Station roof, the eigenvalue buckling, nonlinearbuckling and overall stability analysis; comparative analysis of the primary beginning ofgeometric imperfections, different load conditions, constraints on the truss bearingcapacity.(3) Summarizes the domestic and foreign steel truss design theory and experimentalresearch, described the method of tube truss design, especially in the form of destructionof intersecting KK calculation method of the node and the node and strengtheningprograms. Using the finite element software ANSYS Jinan West Railway Station roofstructure2KK-joints, truss and column connections with the bearing capacity analysis,given the stress and deformation of the nodes.(4) Describes the assembly and lifting of the steel truss roof, formulated Jinan WestRailway Station roof steel truss production and installation. |
