A BRIDGE MANAGEMENT SYSTEM FOR ELEVATED STEEL HIGHWAYS

The Hanshin Expressway network extends some 200 km, forming the traffic arteries of the heavily urbanized Hanshin area around Osaka, the 2nd largest city in Japan. Due to construction restrictions in mature cities, 93% of the total length of this network is elevated, and 77% of the elevated structures use steel girders that have many curves to allow complicated road alignments. These elevated structures are displaying signs of damage after almost 30 years of service life under chronic overload conditions. This paper describes the various types of damage that are frequently found 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. Proposals are presented that may enable the design of more durable steel bridges. In addition, this article briefly discusses a database system being used for the maintenance and management of steel bridges.
