| Abstract: | Combined with the practicle project, based on finite element theory, using cable force under the maximum cantilever of cable-stayed bridge tower, finite element model of steel tower shell is built, and the cable is simulated with only-tension link elements. Using finite element model of steel tower shell, the influence of spacing, thickness, width of the steel tower longitudinal stiffeners on first stability of cable tower is analyzed, the reasonable parameters of longitudinal diaphragm are got. |
