- Abstract
The Hanshin Expressway network extends some 200km, forming the traffic arteries of the heavily urbanized Hanshin area surrounding Osaka, the second largest city in Japan. Due to restrictions on construction in mature cities, 93 percent of the total length of this network is elevated, and 77 percent of the elevated structures use steel girders that have numerous curves to allow complicated road alignments. These elevated structures are showing signs of damage after serving for almost 30 years under chronic overload conditions. This article describes the various types of damage that are frequently detected in elevated steel bridges and, focusing on typical fatigue-induced damage, reviews the repair process that begins with the investigation of causes and potential repair methods and continues through the implementation and inspection of the repair work. Propositions are presented that may enable the design of more durable steel bridges. In addition, this article briefly discusses a database system that is being used for the maintenance and management of steel bridges.
