Background
The RCS composite structure is a novel structural form and is a frame structure consisting of reinforced concrete columns and steel beams. The RCS combined structure system has the advantages of a traditional steel structure and an RC structure. The lateral rigidity and the strength of the RC column are superior to those of a steel column; and RC columns are more economical than steel columns. The construction speed of the steel beam is faster than that of the concrete beam. Compared with a common reinforced concrete structure, the RCS hybrid frame structure has the advantages of lighter self weight, larger available space of a building, higher construction speed and the like; compared with steel structure, the steel structure has lower cost and more excellent performances in rigidity, fire resistance, durability and the like. Based on the above advantages, the RCS composite structure has gained attention from engineers in various countries around the world. Since concrete is a brittle material, when it deforms beyond its ultimate compressive strain, the concrete will collapse and the load bearing capacity will decrease. One of the main failure modes of the RCS node area is concrete bearing failure.

The utility model discloses have following advantage and outstanding effect for prior art:
the utility model provides a spiral steel fiber concrete column and honeycomb girder steel RCS sub-assembly for improve concrete limit compressive strain, and then improve ring type welding stirrup high-strength concrete column and honeycomb girder steel RCS sub-assembly ductility, the regional bearing capacity of reinforcing RCS node. The steel fibers are distributed in the concrete in a disorderly manner, so that the expansion of micro cracks in the concrete is hindered, the occurrence and the development of macro cracks are retarded, and the ductility of the combined column is further improved. In addition, the ductility of the combined column is improved, and the energy consumption capacity of the combined column during earthquake is improved, so that the earthquake resistance of the RCS combined piece of the ring-type welded stirrup high-strength spiral steel fiber concrete column and the honeycomb steel beam is enhanced. The ring-type welding stirrup has the following advantages: (1) the binding force provided by the ring-type welding stirrup on concrete is far greater than that of a common hook stirrup; (2) the common hook stirrup at the beam column node is difficult to adjust, the situations of less placing and no placing of the node stirrup are easily caused, the shock resistance of the frame node is greatly reduced, and the situations do not exist in the ring-type welding stirrup. (3) By adopting the ring-type welded stirrups, the blanking is easy during concrete pouring, and the situations of holes, exposed reinforcements and the like are not easy to cause. In conclusion, the RCS assembly of the ring-type welded stirrup high-strength spiral steel fiber concrete column and the honeycomb steel beam greatly promotes the development and the practical engineering application of the RCS combined structure.
