Hollow interlayer steel pipe confined concrete column, concrete beam joint and building structure

The invention discloses a hollow interlayer steel pipe confined concrete column, a concrete beam joint and a building structure. According to the building structure, the hollow interlayer steel pipe confined concrete column and a reinforced concrete beam are crossed in a concrete beam joint structure; the outer steel pipe of the hollow interlayer steel pipe confined concrete column is broken near the joint core area formed by the intersection of the outer steel pipe and the reinforced concrete beam to form the broken part, so that the phenomenon that the outer steel pipe is bent due to the action of a large vertical load can be effectively avoided, and the outer steel pipe only has a restraining effect on concrete; the bearing capacity and the ductility of the hollow interlayer steel pipe confined concrete column are greatly improved; the end stress increasing portion of the hollow interlayer steel pipe confined concrete column is reinforced through the column end vertical stiffening ribs, and the joint area
