Bending behavior of steel-concrete composite girder with perfobond shear connector using super-light weight concrete with steel fiber reinforcement

Recently, the development of the light-weight concrete with short fiber reinforcement is done to simplify the reduction and the structure section of the self-weight. It is possible of lightening about 30 percent using super-light weight concrete compared with normal concrete. On the other hand, there is a reinforcement method of usually having material strength equal with normal concrete by mixing steel short fiber. This study aims at clarify shear strength evaluation of perfobond shear connectors (PBL) using super-light weight concrete with steel short fiber. In this study, it was carried out push-out test and bending test of composite girder using super-light weight concrete with steel short fiber to clarify the presence of a concrete kind and the fiber mixing. As a result, it/was clarified such as: (1) the shear behavior and shear strength evaluation of PBL and (2) applicability of the PBL in composite girder which using super-light weight concrete with steel short fiber.
