Decision-Making for Highway Bridge Safety

Highway bridge owners in most countries routinely assess bridge damage and deterioration to ensure structural performance for the safety of the traveling public and the reliable movement of goods and services. While in service, bridges experience a variety of incidents involving damage or deterioration. Owners discover this damage or deterioration primarily under two sets of circumstances. First, damage or deterioration resulting over longer periods of time is generally discovered and monitored [...]

Detection of Delaminated and Cracked Concrete with Unmanned Aerial Vehicles

The unmanned aerial vehicles or drones provide eyes that reach the sites and parts of structures that are difficult to access. They are very valuable when high bridges with large spans, which would typically require special vehicles, hoists or personnel with climbing skills, are inspected. If a drone carries infrared sensors and high definition lenses with a long focal length, its scope can be extended to non-destructive damage detection. This article presents the results of a study on the use of [...]

Improvement of Access Equipment on Girders of Honshu-Shikoku Bridges

The Honshu-Shikoku Bridges (HSB) are comprised of 17 long-span bridges which span over the straits, and the bridge girders are at high altitude above the sea. Honshu-Shikoku Bridge Expressway Co., Ltd. is conducting maintenance management of the long-span bridges based on the concept of preventive maintenance, in which action is taken before deterioration progresses. Routine inspection of bridge girder at high altitude and repair painting requires securing safety and high work efficiency. For this [...]
