Girder Bridge

The study describes behaviour of fatigue-cracks for evaluation of structural repair priority. Around 65% of the total length of the Metropolitan Expressway in Japan is composed of viaducts made of steel. And fatigue crack problem has been occurred on the steel structures. In particular, around 30% of all the fatigue-cracks occurred at “Web-Gap Plate(WGP)” which is attached in plate girder bridges. This study focused on the fact that those cracks do not always induce collapse of the girder bridge immediately, even though the number of cracks, which are needed to repair, is becoming increasing. As a result of the study, repair priorities of around 60% cracks on WGP can be lowered by analysing maintenance data accumulated since 2001.

Fire Accidents

<p>Fire damage to bridges occurs frequently in Japan and in other countries. Previous bridge fire accidents suggest that it is important to understand the structural performance of the bridges after their exposure to fire. The authors have studied the evaluation of the stress of the steel- concrete composite girder bridges as a simply supported bridge damaged by fire. First of all, fire test was carried out to clarify the temperature distribution of the composite girder and a static loading tests before and after fire were conducted to confirm the effect of the reduction of rigidity from fire. Next, numerical analysis was carried out to indicate the stress distribution and deflection on the composite girder bridge from live load after fire.</p>
