PROBLEM TO BE SOLVED: To provide an elevated station structure low in construction cost with a large degree of freedom in station layout and a small influence on a construction period. SOLUTION: A building structure section 2 is constructed in a state of covering the periphery of a viaduct section 1. A part of seismic force and load such as wind load applied to the building structure section 2 is supported by the building structure section 2 itself. The remainder of the load on the building structure section 2 is supported by parts S1, 14L, and the like on the outside of the viaduct section 1, and joint parts with the viaduct section 1 are composed of a simple support fulcrum and a hinge joint so as not to transmit bending moment to the viaduct section 1. One end of a platform 11L or the like of the viaduct section 1 is supported by an intermediate part of a building column 21L or the like of the building structure section 2, and the building structure section 2 bears a part of load of the platform 11L or the like. The elevated station structure 100 is thereby formed in hybrid structure combining the viaduct section 1 which is a civil engineering structure, and the building structure section 2 to skillfully share the load.
