To provide an elevated structure which has high structural reliability imparted thereto at a joint portion between a pier stud as a lower structure and a horizontal beam as a super structure, and can be constructed in a relatively short construction period.

The elevated structure is formed of the pier stud 20 of a prestressed structure, which is obtained by stacking up cylindrical precast blocks 21 each having insertion holes for insertion of reinforcements and prestressing bars 22, inserting the reinforcements and the prestressing bars into the insertion holes, respectively, and pouring grout into the insertion holes, and the steel box girder 10. Then a steel annular body 14a arranged on a lower surface of the steel box girder is fitted onto an upper edge of the pier stud, and the prestressing bars are projected upward from the upper edge of the pier stud to be inserted into predetermined locations of the steel box girder, followed by anchoring upper edges of the prestressing bars to the steel box girder by means of anchorage devices 26, to thereby joint the pier stud of the PC structure and the steel box girder together.
