The invention discloses a concrete-filled
steel tube column provided with a soft steel
bushing and embedded with a high-tenacity material. The concrete-filled
steel tube column comprises an inner
pipe (1), core concrete (2), a soft steel
bushing (3), bolts (4) and a high-tenacity
composite material (6). In the invention, the bottom of an ordinary concrete-filled
steel tube is provided with the soft steel
bushing (3); and the high-tenacity
composite material (6) is embedded into the space between the soft steel bushing (3) and the inner
pipe (1). Under the action of conventional earthquake, the bottom soft steel bushing and an concrete-filled steel tube column have high overall working performance, high rigidity and high strength; and under the action of rare earthquake, shearing damage to the bolts is severe, the connection between an inner
pipe and an outer pipe is weakened, the co-working performance degenerates, the
ductility and
energy consumption functions of the inner pipe and the outer pipe are brought into full play respectively, the overall regality is reduced, the structural period is prolonged, and the earthquake action is reduced; and after the soft steel bushing is arranged, an earthquake
fortification line is increased, the
structural safety is enhanced, and early impairment and damage to a high-strength steel plate are prevented and delayed.
