For example, the space required to construct these structures is smaller than that of other bridges due to the footing being removed, meaning that it is not necessary to greatly change the surroundings of these bridges. While there are environmental and landscape advantages, there are also a few demerits for the overall landscape designs, including demerits in the design of this proposed structure which consists of relatively slender parts. This proposed structure has already been constructed in areas where possibility of a severe earthquake is low. However, some problems that have yet to be examined are related to the use of this proposed structure in areas where earthquakes are frequent. Lacking detailed studies of its behavior during severe earthquakes, it is currently difficult to construct these structures in Japan. Consequently, it is necessary to investigate in detail limited performance about compression and bending moment, and earthquake-resistant performance of these structures in order to resolve these problems. The authors had previously clarified the relationship between the rigidity of the ground and the effective buckling length, and the compressive strength of the Pier-Pile Integral Steel Structure. Moreover, we had proposed a simplified formula using a proposed characteristic value, and had revealed the relationship between effective buckling length and compressive strength of the Pier-Pile Integral Steel Structure. In this paper, we verify the compressive strength after confirming the residual stress of the ERW (Electric Resistance Welded) pipes. Moreover, the relationship with the Euler curve and the load-bearing capacity curve of box-shaped cross-section from the Japanese standards is clarified.
