A time-dependent reliability prediction of deteriorating spun concrete bridge piers

Abstract

The conceptions of the time-dependent reliability analysis of non-deteriorating and deteriorating spun concrete bridge piers, which are effected by permanent and transient loads, are discussed. There are analysed the first- and the second-order load effects of bracing bridge piers. The strength features of resisting bending moments used in ultimate limit state and probability-based designs are presented. A simplified analysis of non-deteriorating and deteriorating bracing spun concrete piers in persistent situations in limit state and probabilistic approaches is provided. The prediction of probability-based reliability on shafts of non-deteriorating and deteriorating bracing bridge piers is illustrated by numerical example.
