Research on Joint Design of Basement Floor with Rectangular Steel Pipe Column Extending Downward
This paper introduces the practice of connecting steel columns and reinforced concrete beams at the top of the basement of rectan-gular steel tube concrete columns in two types of steel structures.Based on the actual engineering situation,optimization schemes for speci-fications and standard drawing practices are proposed,along with corresponding specific design measures.The welding reliability of this joint is verified through reinforcement tensile tests,providing theoretical basis and practical experience for related engineering designs.
