Considerations on the behavior of Incheon Bridge, Seul, South Korea to the action of un uniform sunshine, comparison study to the extreme temperature's exposure periods

摘要

Structural monitoring has become a current activity in the life of constructions. In terms of responding to stress and the required frequency for determinations, structural monitoring can be classified into three segments: static, quasi static-quasi dynamic and dynamic, with specific tools, technologies, methods to each group, some of these being common. The analysis of a building's construction must also include a good knowing of the characteristic environmental factors in the location area, but in order to optimize the design solutions, the behavior models provided by the data banks (future) become a must. In setting up these data banks the main information is provided by the topo-geodesical activity, which must coordinate the entire monitoring process for the tracking of the behavior after the action of environmental and exploitation factors. The case study, in continuous quasi-static condition, was performed on Incheon Grand Bridge South Korea. At 12.3km long with a main cable stayed span of 800m the new Incheon Bridge will be one of the five longest of its type in the world. VCE Vienna Consulting Engineers ZT GmbH is an independent, high tech oriented consulting firm with its head office in Austria. The company operates in four principal lines of business: 1. the transportation sector (including bridges, tunnels and railways); 2. the building and industrial sector (general design and management as well as specialized technological expertise); 3. the development sector (from research and development to feasibility and environmental studies, financial engineering, to development aid); 4. the structural health identification (BRIMOS) and Life Cycle Engineering.
