The Analysis And Calculation Of Equal Catenary Arcade's Internal Forces

As the highway bridge's foundations changing and changing, the arcadecalculation is important and important in recent years. So how to calculate arcade's internal forces quickly and exactly is an important thing in study. This paper's foundation is the "Hardness Conversion Mode", which was advanced by prof. Wang GuoDing. Another, the paper adds the calculating fixed arch theory. Using the preceding theory, I designed the computer programs, which could calculate the catenary arcade's internal forces. The programs use Quick Basic to design. The inputting data use the methods, which between computer and man. It is very easy and quick. The outputting results apply engineers' habit. All of the results are verified by interrelated examples. The results are precise. The program in this paper could be used by teachers, students and designers.
