The invention discloses a connected node of a concrete filled
steel tube combination column and
reinforced concrete beams. The concrete filled
steel tube combination column and the
reinforced concrete beams are intersected to the connected node. Open holes are formed in steel tubes, corresponding to the intersected positions of the
reinforced concrete beams, of the concrete filled
steel tube combination column. The upper end and the lower end of each reinforced concrete beam and the upper end and the lower end of the concrete filled steel tube combination column are respectively provided with two open holes, namely two upper end open holes and two lower end open holes. Longitudinal ribs inside reinforced
concrete beams penetrate through the open holes in the tube wall and are anchored on core concrete inside the steel tubes. The positions above the upper end open holes, the positions below the upper end open holes, the positions above the lower end open holes and the positions below the lower end open holes are respectively provided with an annular reinforcing plate. Vertical reinforcing plates are arranged on the portions, between the open holes which have the same height and small gaps, of the tube wall. The concreted node of the concrete filled steel tube combination column and the reinforced
concrete beams is used under the condition that multiple beams are slantly intersected to the node in a small-angle mode, and holes are closely formed in the tube wall. When the heights of the cross sections of the multiple beams are different, the beam longitudinal ribs can also penetrate through the large open holes conveniently. According to the connected node of the concrete filled steel tube combination column and the reinforced
concrete beams,
stress concentration between the open holes of the tube wall can be conveniently controlled, meanwhile, the hoop effect of the tube wall with the open holes is reinforced, and the anti-seismic performance of the node can be ensured.
