- Comparison of cable safety factors of steel cable-stayed bridges and extradosed bridges
抄録
At present safety factors are differently specified for steel cable-stayed bridges and extradosed bridges; 2.5 for steel cable-stayed bridges and 1.67 for extradosed bridges. Parametric studies were conducted for both bridge types with the same center span of 205m using cable safety factors as parameters. Both the ultimate and fatigue strengths of stays were evaluated for different cable safety factors. For steel cable-stayed bridges, the ultimate strength of stays are critical than the fatigue strength, and the safety factor of 2.5 is necessary to satisfy the required ultimate strength. For extradosed bridges, the ultimate strength of stays are also critical than the fatigue strength, and the safety factor of 2.1 to 2.8 is necessary depending on the load factors.
