Optimization Design of Cross-Section of Prestressed Steel-Concrete Composite Box Girder
According to the design specifications and structure theories of prestressed steel-concrete composite box girder, a mathematical model of optimization of cross-section of prestressed steel-concrete composite box girder was established. The nonlinear constrained optimization was adopted and the computer program was compiled with Matlab language. The efficiency optimization was achieved in the optimization design of the two different span bridge cross-section of a simply supported steel-concrete composite box girder. Numerical result illustrated that the optimization mathematical model of optimization was exact and the algorithm effective.
