| Abstract: | This paper probes into methods to analyze line shapes of cables in asymmetrical suspension bridges.A programming flow chart is designed to program line shapes of main cable on final status and free-cable status by means of MATLAB software,and the Puli Suspension Bridge is taken as a computation example to verify correctness of program.The computation shows this method has features of convenience for use,fast speed in computation and high precision,etc.and can be applied in design and construction. |
