◆ Key Projects

Double Composite Box Girder Bridges: Research Project Name : Development of Structural System for Advanced Double Composite Box Girder Bridges
Supporting Ministry : Ministry of Land, Infrastructure, and Transport
Project Dates : 2006.12. ~ 2009.12.

Research Objective : Development of element technology for the construction of double composite steel box girder bridge with span length of less than 100m, which ha advantage in reducing the cost of manufacturing and installation
Improvement of the reinforcement structure and development of new concept in shear connector of the steel box girder compression flange
Development of the technology for the designing of the bottom slab of double composite steel box girder
Development of the efficient design technology for diaphragm at support
Development of economic construction method

Characteristics of the Developed Technology
Safe, economical, and convenient construction
Reduction in the positive moment and deflection of the center portion of the span due to the increase in the rigidity of the internal support section
Reduction in the use of steel materials by more than 20% in comparison to the composite girder bridge
Reduction in the cost of manufacturing due to reduction of stiffener for the bottom flange
Advantageous in reducing vibration and deflection, as well as in securing overhead clearance of the bridge
Possible to plan beautiful and economical long-span bridge
Substituting the high cost short span bridges (arch, truss, PSC box, etc.) for the bridges that need to be economical and long-span (50~120m)
Satisfying the conditions of the positive moment and deflection limitation of the central span section of the bridge that needs reduction in noise and vibration such as the railway bridge
Applicable to long-span due to the low depth of main girder
Reduction of steel materials for bridge construction
