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 [...]
Safety and Extension of Life Time of Road Bridges
Road bridges are fundamental infrastructure in all national, regional or local road networks. In many developed countries, significant budgets were invested on road infrastructure including road bridges during the economic growth. Due to this situation, many developed countries are facing a problem related to aging of road bridges. Developing countries have devoted their investment to infrastructure in more recent times and will face similar aging issues in the future.
Emergency Communications At The Forth Bridges
Scotland’s Forth Bridges provide a pertinent case study on the use of web media and social networks to manage emergencies on an important transport link.In June 2015 the Scottish Ministers, through their agency Transport Scotland, appointed a new Operating Company to take over the management and maintenance of the Forth Road Bridge. They chose to keep and evolve existing web-based communication channels in order to retain followers and capitalise on established trust and goodwill.
