A Study on Shear Characteristics for FRP Composite Girder Filled with Concrete

This study suggested a section of a new module that will allow for applying a large section in order to solve the technical difficulties mentioned above and to secure low stiffness of FRP, developed a new FRP + concrete composite girder that is filled with the appropriate amount of concrete. To identify the structural behavior of this FRP + concrete composite girder, experiments were conducted to measure its shear strength according to the difference in the strength of confined concrete and variation of the shear span to depth. The results of the shear strength test confirmed the composite effect from confining concrete and the effect of increase in strength proportional to the strength of concrete.
