Cable-stayed bridges usually have more complicated and high-indeterminacy structural behaviors. The first part of this study is to introduce the characteristics of girder, pylon, cable and their related designs. Though the safety and stability of the constructed cable-stayed-bridge is important, more consideration should even be given to its feasibility during construction. The second part of the research studies two bridges in Taipei and adjust the changing of cable forces and bending moments of deck during construction by using cantilever method and cantilever method with far end staging method. The static analysis software “TANGO” is used to analyze cable prestress, vertical displacement, bending moment, axial force, and shear force so that stress can be calibrated to ensure the design fit the requirement of specifications.
