ABSTRACT
ABSTRACT: For a decade many countries and institutes in the world have developed many kinds of management system of bridges. Generally the management system is composed of maintenance system to control manually and monitoring system based on the automatic remote sensors, where the systems are not compatible with each other because of some reasons. When Young-Heung Bridge opened recently, the maintenance and monitoring systems are integrated with the latest technologies and equipments. Thus, Visual Interface Module (VIM) is developed for easy use of structural database in main controlling computer to manage all information and field tabletcomputer to collect visual inspection data. Besides, the computer can save the detail map of structure damages as well as visual rating at once. The gathered information of the every element is sorted in accordance with bridge inventory and evaluation systems of bridge condition along time. In addition, the rational algorithm of bridge condition (RABC) makes a quantified visual condition of element and bridge rating. On the other hands, many sensors, such as anemometers, accelerometers, inclinometers, strain gauges, and thermometers, monitor the behavior of the cable bridge. The measured results are automatically sent to main system. These two systems are used for mutual reference of structural safety and integrated condition assessment of cable-stayed bridge. This development serves to overcome many problems and weakness of existing bridge management systems and may be helpful to other maintenance agencies.
