ABSTRACT
ABSTRACT: The load carrying capacity of steel bridges can be affected by corrosion. In addition to natural aging and increasing load spectra, corrosion is one of the main causes of deterioration. Structures exposed to aggressive environmental conditions, are subjected to time-variant changes of their load carrying capacity. Therefore, there is a need for evaluation procedures to accurately assess the actual condition and predict the remaining life of the structure. The load and resistance parameters are random variables and reliability can be used as a rational measure of structural performance. The objective of this paper is to present time-variant system reliability profiles developed for steel girder bridges.
