- Abstract
- This paper presents the reliability analysis of the pylon for Yi Sun-sin Bridge. In order to evaluate the reliability index and most probable failure point(MPFP), the advanced first-order secondmoment method with the double iteration loops is adopted. Random variables are load and strength parameters which are associated with the load effects and the pylon strength, respectively. The limit state function is defined by the P-M interaction diagram. The sensitivities of the limit state function are calculated by the direct differentiation of P-M interaction diagram. To construct the continuous and differentiable function, the discrete points of P-M interaction diagram are interpolated using cubic spline method. The reliability analyses of the pylon for Yi Sun-sin Bridge are conducted for the design wind load and service wind load.
