Abstract

The methodology and strategy for evaluating fatigue damage and possible critical locations of local fatigue on bridge-deck sections are developed, using the real-time monitoring data and the fatigue damage model based on continuous damage mechanics. A local damage model for evaluating the fatigue damage of bridge-deck sections is proposed, which allows fatigue damage to be considered at the continuum scale as a deteriorating process with its physical mechanism such as fatigue crack initiation and growth. Therefore the fatigue damage variable associates not only cycles of stress range on the accumulated process of fatigue, but also relates directly to the state of deterioration and the mechanics behavior in supporting the net stress. The effective stress range for the variable-amplitude stress spectrum due to traffic load is used to evaluate the fatigue strength of the bridge-deck section at different locations of strain gauges, by which the possible location of critical fatigue failure can be primarily determined. The method has been successfully applied to the Fatigue Damage evaluation for a suspension bridge under Typhoons and Overload Effect.

Citation countsare sourced monthly from Scopus and Web of Science® citation databases.

These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.

Citations counts from the Google Scholar™ indexing service can be viewed at the linked Google Scholar™ search.
