An influence of rivet loss on load carrying capacity of bearing members

Abstract

Focusing on the girder end of a steel bridge, it tends to corrode easily due to the effects of moisture and dust. In the case of multiple plates are joined together under compressive stress, rivet head loss can cause plate separation. When this happens, out-of-plane deformation or buckling may occur, and affecting the load carrying capacity of the bearing members. In this study, 4 cases of loading experiments using removed riveted girder were conducted with different positions of missing rivets. It was found that stiffness decreased within a certain range of load in case of rivets at the lower ends of stiffener side and web side were removed simultaneously. However, all cases showed load carrying capacity almost equivalent to that of intact case.
