BACKGROUND ART Durable structures commonly constructed in the past employ structures made of a combination of steel and concrete. Most of them are made of steel frames or composites of reinforcing bars and concrete, and most of them are constructed on-site. There are underground pipes that have a steel shell and are filled with concrete, but the idea is that the concrete and reinforcing bars filled in the steel shell will resist external forces. This cannot be said to be a steel-concrete composite structure that fully utilizes the advantages of steel and concrete. In addition, such structures made of a composite of steel shell and concrete are hardly used at present, except for special items such as buried pipes, but recently they are being used for offshore structures etc. Research is underway and several proposals have been made.
