| Abstract: |
The basic design concepts for the limit state design code under development in Korea for the longspan cable-supported bridge are presented. Considering the importance of the structure, higher target reliability level and longer design life are defined compared to those of the ordinary bridges. In deciding the amount of safety increase, the construction cost and the consequence of structural failure are examined. Safety factors including the importance factor which is multiplied to the design strength of the structural member are calibrated through reliability analysis of the actual design examples. It is also shown that the nonlinear analysis of the cable-supported bridge yields higher reliability index of the main cable than that obtained by the linear analysis. |
