I. Definition and needs for Research Project
□ Definition of Intelligent Green Bridge
∘ Intelligent Green Bridge (IGB) is the eco-friendly bridge to guarantee carbon
Reduction of 30% and service life of 100 years.
∘ In order to reduce the carbon emission and prolong the service life, IGB has the
intelligent strategies based on convergence of various state-of-art technologies
and is managed by proactive planning and management over the life-cycle of a
bridge (i.e., Design, Construction, Operation, and Maintenance)
□ Needs of Intelligent Green Bridge
∘ Compatibility with national policy for reduction of carbon
∘ Mandatory adoption of BIM to large construction projects
∘ Needs for development of bridge management system (Design, construction and maintenance) for longevity of the service life
∘ Preparation of solution to rapidly increasing deterioration of existing and new bridges
∘ Needs for extension of economic perspective from construction cycle to life cycle
∘ Needs for improvement of bridge management system in terms of environmental effect by including life cycle assessment
2. Domestic/International trend and Analysis
□ Political trend
∘ Eco-friendly and IT-convergence technologies are encouraged in the level of government
∘ Emerging needs for development of eco-friendly technologies in order to minimize carbon emission during life cycle of bridge
∘ Needs for the technologies considering public convenience
∘ Needs for efficient and economical maintenance technologies to maneuver the deterioration of the existing bridges.
∘ Deficiency of policy and integrated system for structural safety and diagnosis
□ Economic trend
∘ Mandatory adoption of BIM since 2012
∘ It is required to consider the costs such as maintenance, carbon emission over life cycle
∘ International efforts are focusing on the development of long-term (or prolonged) bridge technologies due to rapid increase of maintenance cost
∘ In the level of government, the budgets for maintenance/retrofit/repair is increasing globally
∘ Although domestic market for maintenance is gradually increasing, the original technologies are highly depending on oversees country
□ Technical trend
∘ Adoption of BIM is extended to mandatory for public construction in US and EU, while the level of development is at a stage of infancy
∘ Long-term and economic technologies based on higher performance and eco-friendly materials is developing in US and EU, related domestic research is focusing on the development and application of eco-friendly materials
∘ Construction of bridge by using rapid construction is active in US, its application is limited to new bridges. Their economics is not affordable to in-site construction
∘ International and domestic level of maintenance is limited to construction of maintenance systems and measurement of data from the response of bridges
