This research focused on innovative maintenance technologies for infrastructure especially for steel bridges and sign and lighting structures on viaducts. The following themes are discussed.1) Bridge Weigh-in-Motion and its application for environmental monitoring.A truck load survey was carried out the National Route 19 by Bridge Weigh-in-Motion. A synchronized monitoring of truck load and traffic induced noise of bridge joint was carried out at Kojima Viaduct of Higashi Meihan Expressway. The effect of truck load and vehicle speed on the noise level was discussed.2) Fatigue durability assessment of steel bridgesFatigue tests of fillet weld joints, such as cover plated end details and tensile plates with fillet welded pipes, were carried out. A new method of fatigue durability assessment was developed. Several strengthening methods of welded joint were discussed.3) Vibration and fatigue problem of sign and lighting structure on viaducts.Vibration reduction methods for sign structures on viaducts were developed. A feasibility study of visual observation for vibration rating was carried out.4) Digital image analysis for structural health monitoring.A simple method of surface profile measurement for corroded steel surface was developed.

这项研究的重点是基础设施的创新维护技术，特别是钢桥和高架桥上的标志和照明结构。1)桥梁动态称重及其在环境监测中的应用。利用动态桥梁称重对19国道进行了卡车载重调查。对东美韩高速公路小岛高架桥进行了车载与桥头交通噪声同步监测。讨论了载重和车速对噪声水平的影响。2)钢桥的疲劳耐久性评估对角焊接头进行了疲劳试验，如封口板、端部细节和带角焊管的抗拉板。提出了一种新的疲劳耐久性评估方法。3)高架桥标志及照明结构的振动与疲劳问题，提出了高架桥标志结构的减振方法。4)结构健康监测的数字图像分析。提出了一种简单的锈蚀钢材表面轮廓测量方法。
