Steel Box-Truss Hybrid bridge consisted with steel box type in positive moment that is allowed to resist with low depth and truss type in negative moment is new type bridge. This can be used as 80m∼150m long span bridge and is economical structural type. But safety of truss type is concerned because of torsion that occurs when Steel Box-Truss Hybrid bridge applies a curved bridge. Therefore, it is necessary to analyze and evaluate straight and curved bridge for commercialization of Steel Box-Truss Hybrid bridge. In this study, structural analysis of Steel Box-Truss hybrid curved bridge with various curvature is performed and compared with member force and displacement of Steel Box-Truss Hybrid straight bridge. Also the applicable limited curvature of Steel Box-Truss Bridge form is proposed.
