| Summary: | 碩士 === 中原大學 === 土木工程研究所 === 91 === The target of this research is about the cable-stayed bridges, including the introduction of cable-stayed bridges, the design and structural analysis of cable-stayed bridges. In addition, we take two examples: Erl-Chorng Cable-Stayed Bridge (single tower, double plane fan configuration, symmetrical steel structures) and Kao-Ping Hsi Cable-Stayed Bridge (single tower, single plane fan configuration, asymmetrical compound structures). By studying these cases, we can see the difference between the cable-stayed bridge and the traditional bridges in design flow and behaviors, and can optimize the design and save materials.
In the study, we use the professional design program, TANGO, to analyze the examples of cable-stayed bridges, to do the comparison of structural behaviors of the cable-stayed bridges in different loading conditions and to obtain the deflection and internal forces (moment, shear force, axial force, etc). Cable replacement is another text topic of this research, which is very important for maintenance. The AISC specification is used to check the allowable stress and P-Δ effects.
