THE OPTIMIZATION OF CABLE TENSIONS FOR A CABLE-STAYED CONCRETE-FILLED STEEL TUBULAR ARCH BRIDGE
The general situation of a cable-stayed concrete- filled steel tubular arch bridge under construction and the tensional stages of the cables are introduced. Then, optimizing objects of typical construction cases are discussed according to its design and constructing features. Finally, the theoretical cable tensile forces of typical construction stages are calculated, by the influence matrix method, considering the adjust of the calculating parameters of the finite element models by utilizing the data tested on site. Comparison of both cable tensions and stresses on key section after the first concentrating regulation of the cable tensions, show good agreement.
