The Application Of Computer Simulation Technology In Large Span Pre-stressed Three-dimensional Tube Truss Construction

Large span prestressden steel truss structure is rather complex in its bearing carrier, In order to understand the controlling inner force and deformations in structural design, the paper made a analysis and calculation for the whole model of Prestressed three-dimensional truss. Meamwhile the author also did the calculation for the selection of the three-dimensional truss fxing node, and by using the general assembly programming to establish a large element analysis entity of the finite element analysis of the unit. During construction, the author made a analytic calculation for the determination of the size in the initial state, and for th strength of construction, the evaluation of stability. The author also makes a computer simulation for the stuctural deformation in the process thus to offer a scientific and reliable support for the organization of the construction.
