SOLUTION: This steel bridge 1 for supporting a floor slab 30 is composed of right and left main girders 20 and 10, both of which are formed of weatherable steel. A right-side additional member 28 as a nonstructural member, which is protruded from a windward side surface 241 of a right-side web of the right main girder 20, is mounted on the windward side surface 241 of the right-side web of the right main girder 20. A position to mount the right-side additional member 28 is set as a position to divide the windward side surface 241 into a windward side highly-corroded portion 241A of the right-side web, which is estimated to be corroded to a predetermined degree of corrosion or above, and a windward side low-corroded portion 241B of the right-side web, which is estimated to be corroded to a degree of corrosion under the predetermined degree of corrosion. A coating film M is formed by applying the anticorrosion coating to the highly-corroded portion 241A.
