Analysis of Fatigue Behavior of Steel-Concrete Composite Bridge Deck

摘要

Bridge deck is directly exposed to external environments and traffic loads. The deck can be more easilyrndeteriorated than other bridge members and is often needed to be repaired or strengthened during the service life.rnTherefore, development of high strength and durable bridge deck that requires minimum maintenance during the servicernlife is demanded. This study has been conducted to obtain basic data that are essential for the establishment of a fatiguerndesign guideline of a steel-concrete composite bridge deck. The developed deck has high flexural rigidity compared tornthe conventional reinforced concrete deck. In this paper, the results of a detailed structural analysis and a fatigue test onrnthe developed deck are presented. A guideline for the fatigue design of the developed deck is also proposed.
