Study On The Method Of Analysis And Computing For Bridge Structure Based On Object-orientation

The computational analysis of the bridge structure occupies sizable proportion in the engineering application and research, with the fast development of the computer, there is sizable improvement in the computational analysis technology of the structure. At present , a lot of powerful structural analysis program have already been developed at home and abroad, such as ANSYS, SAP, ADINA, ABAQUS ,etc.. But these structural analysis software are impossible to solve all problems, and, with the development of engineering, new problems will emerge constantly. But structural analysis program involve various content, it costs a large number of man-hours to work out structural analysis procedure of the bridge by traditional structured programming, and it has a lot of restriction in expandability and code reuse. object-oriented programming make software programming get rid of these unfavorable factors. the unified object-classified method is adopted, and in the programming course, objects can be assembled to a program, and add new operation function in new objects to set up the program which meets one's own specific demand. Because of a great deal of advantages, object-orientation programming method is becoming mainstream in program design. The object-oriented thought is applied to the bridge structure analysis, and programming thought of each module is descript in details. The pre-stressed effect analysis, the continuous variation effect analysis and the movable load effect analysis are introduced. The theory and method of special questions in the bridge structure are elaborated。The principle which expands the bar system analyzer to construction simulation function procedure is introduced 。 The technology which introduces the modern software development technology and pre or post processing technology is introduced, including the object-oriented program design program, the software development technology of software component object model, and the main function of pre or post processing module in bridge analysis system.
