Nonlinear Flexural Modelling of Composite Prestressed Concrete Beams Reinforced with Advanced Composite Materials

복합 신소재 프리스트레이트 콘크리트보의 비선형 휨 모델링

The analytical model is developed in order to predict the nonlinear flexural responses of bonded and unbonded prestressed concrete beam which contains advanced composite materials. The block concept is used, which be regarded as an intermediate modeling method between the couple method with one block and the layered method with multiple sliced blocks in a section. The model can successfully predict the flexural behavior of variously reinforced prestressed concrete beams.
