Background
The connecting structure of the beam-column joint of the steel reinforced concrete frame has the advantages of simple structure, clear force transmission, and convenience for concrete pouring and reinforcing. The beam-column connection mainly comprises the following three modes of (1) connecting a profile steel concrete column with a steel beam; (2) the connection of the section steel concrete column and the section steel concrete beam and (3) the connection of the section steel concrete column and the reinforced concrete beam. The node (1) and the node (2) have very mature practices in the conventional canonical graph set and are very widely applied. The application scenes of the nodes (3) are relatively few, but for the joint of two structural systems, more connecting nodes of the concrete beam and the steel column appear, and individual conditions are special and cannot be directly applied or refer to the connecting nodes concentrated by the existing standard diagram. Particularly, the top steel bars of the concrete beam are anchored in the concrete layer above the reinforced plate at the top of the steel reinforced concrete column, the concrete layer is too thin, the anchoring force of the upper steel bars cannot be dispersed, and great potential safety hazards exist. Therefore, specific node design is provided for special situations of actual engineering, and technical references are provided for similar engineering.
