Abstract
The present invention relates to a concrete-filled steel tubular column-steel plate concrete ring beam joint, comprising: a concrete-filled steel tubular column, a steel plate concrete ring beam and reinforced concrete frame beams. The steel plate concrete ring beam comprises: a steel plate and a reinforcing cage, wherein concrete grouting holes are arranged in the middle of the steel plate; both the steel plate and the reinforcing cage are of a ring shape, and the ring-shaped steel plate and the reinforcing cage are coaxially arranged; the steel plate concrete ring beam is sheathed and fixed on the outer side wall of the concrete-filled steel tubular column; and an end of the reinforced concrete frame beam extends into the steel plate concrete ring beam, and stressed reinforcements of the reinforced concrete frame beam are connected to the steel plates. The steel plate concrete ring beam is of a centrosymmetric ring-shaped or eccentric ring-shaped construction. The stressed reinforcement of the reinforced concrete frame beam is anchored by the ring beam joint through the steel plates, so that the seismic performance of the connection joint is ensured, the section width of the stee…
