Structural Behavior of Polymer Concrete Bos Girders

폴리머콘크리트 박스 거어더의 구조적 거동

The box girder was developed using polymer concrete, box girder were made for flexural behavior evaluation. The box girder was reinforced with reinforcing steel bars and fiber glass roving cloths. Failure loads were 13.5 tons and 16.6tons for steel reinforced girder and fiber glass reinforced girder, respectively. Especially for the fiber glass reinforced girder, the shape was not changed even after failure. It is expected that application of this idea will be useful for developing under ground box, girder, utility tunnel, small stream bridge box, etc.
