PURPOSE: A steel girder for a bridge is provided to minimize resistance caused by a wind load and to improve torsional rigidity by minimizing a distance deviation from the center thereof to the position of each member. CONSTITUTION: A steel girder for a bridge comprises first and second semicircular section steel members(110,120) and a pair of closed section steel members(130,140). The first and second semicircular section steel members are curved outward and face each other. The closed section steel members have a closed curve cross section and are welded to the ends of the first and second section steel members. |
