It will be important to forecast future the deterioration of remaining strength on corroded members for working out reasonable maintenance scenarios on steel structure. In this study, the buckling strength analyses, including future forecast, were co

The load bearing capacity of an existing corroded pony truss bridge, which is used for 100 years was estimated from FEM results for whole bridge model. The beam element model is to clarify that the influence of the residual out-of-plane deformation i

In steel plate girder railway bridges with open deck system, damage caused by local corrosion of the upper flanges under sleepers is well-known. This damage reduces ultimate strength of the main girders significantly (e.g., in the case of 50%-corrode

In Japan, many steel railway bridges were constructed during the period of rapid economic growth in the 1960s. Now, as over 50 years have passed, the condition of these aging structures has become conspicuous, and a major social problem. In particula

The ultimate slip strength of a perfobond strip (called "PBL" hereafter) depends significantly on the concrete confinement conditions around PBL hole as well as concrete shear fractures at the hole. If the hole is small, the effect of concrete confin

Perfobond strip (called PBL, hereafter) proposed by Leonhardt in Germany is widely used as the validated shear connector in steel-concrete composite structures. Fujii et al. proposed a fracture mechanism of PBL as follows: Slip force (shear force) ac

This paper presents the results of a nonlinear finite element analysis to determine the remaining ultimate strength of a ferry bridge with local corrosion at the girder flange. The ultimate strength decreases with the corrosion thinning of the flange

In Japan, there have been found a lot of corrosion damages recently in steel bridges aged for fifty or more years. If the strength of a steel structure is decreased by serious corrosion damages, the structure must be repaired to ensure its safety. In
