| Abstract: |
Akutagawa Bridge is a continuous rigid frame bridge located between Takatsuki junction and Kobe junction on the New Meishin Expressway. This is where the new concrete precast "Butterfly Web Bridge" was applied, which uses butterfly shaped panels fabricated in a factory. Compared to a conventional concrete box-girder structure, this unique structure enables the reduction in dead load of the superstructure by approximately 10%. And, a decrease in construction costs is expected through the reduction of both prestressing steel weight and size of bridge substructure. |
