This research introduces the process of determining the reliability-based wind load factor. Limit state is focused on strength limit of pylon along with in-plane moment. Reliability analysis is performed based on the probability model of wind load which is composed of analysis factor, pressure coefficient, exposure coefficient, gust factor and wind speed and the probability model of moment resistance of pylon. Target reliability indices are determined based on the moment resistance of real bridges and the minimum required resistance obtained from design code. The wind load factor satisfying the limit state is proposed. |
