Beam Bridge Structural Analysis Program To Calculate

The curved beam finite element method, which is based on the theory of curved girder structure analysis, has been adopted for analyzing the curved bridge structure in this Paper. A curved bridge analysis model is built, the force that acts on the curved bridge can be divided into two independent kinds, the disposal of the internal force and the displacement are similar to the force, with this way, the all possible internal force of curved bridge can be calculated in space. Combined with the structure stiffness method, SACB (Structure Analysis Program of Curved Bridge) is compiled in the environment of Visual Basic 6.0. Program has friendly interface, it imports the data with the Excel, which make the data disposed more conveniently. Program can analyze the multi-girder curved bridge, by using the diatropic distributing theory. It can calculate the dynamic programming loading, by using the combined influence. It can analyze the internal force under the action with the prestressed force, by using the equivalent load method. Then, with comparing and analyzing, three examples are taken to verify the reliability of the calculation method and the result of program in this paper.
