Recently, High Performance Steel, HPS, especially for bridge construction has been developed, named SBHS. Although SBHS has high strength and high weldability, SBHS steel has not been widely adopted in bridge constructions in Japan, because SBHS steel has not been specified in the Specifications for Highway Bridges in Japan. In this research, bending and shear strength of SBHS I-girder were experimentally investigated, and test results indicated that SBHS I-giders can be designed safely using concepts adopted in current specifications. In addition, residual stress distriutions in SBHS I-girder were measured to confirm no negative impact exist against the strength.
