The steel track beams of the straddle-type monorail bridges have been used for straight and curved long span bridges over wide rivers and roadways, and also for complicated curved bridges. In this paper, the numerical calculations of the stresses of steel track beams of various span lengths and curvatures are performed using equivalent uniform load, practical calculation formulas of the curved track beam, and practical calculation formulas to determine the section of the track beam, which are newly suggested. The technical characteristic properties of the steel track beams are clarified by the comparative stress values, such as the section forces on the bearing, vertical reactions, bending moments of the span center and thickness of the track beam elements.
