FATIGUE OF END FLOOR BEAM CONNECTION PLATE OF STIFFENED ARCH BRIDGE

Abstract

In a stiffened arch bridge, a fatigue crack was detected at a plate connecting the top flange of an end floor beam to the main girder. In this paper, the stress which induced the fatigue crack is evaluated by the three-dimensional framed-structural analysis of the stiffened arch bridge, and then the relation between the stress and its overall behavior is discussed.
