碩士 === 中原大學 === 土木工程研究所 === 96 === The first part of this thesis focuses on general introduction of extradosed bridge , including the historical review , structural analysis and design criterion based on the specifications. The second part analyzes a practical example designed by Taiwan engineers in order to illustrate the fundamental principles and structural behaviors of extradosed bridge .In this part a statically structural analysis is completed to show the differences of design flow chart between the traditiomal bridge and extradosed bridge . Finally , a discussion and suggestion is presented based on the results of the previous analysis.The professional software programs are used in this thesis to do the analysis. The variation of internal forces and cable forces under various load combinations have been studied. The envelopes of internal stress is drawn to ensure the stress which meet the requirements of design codes.
