SUITABLE JOINT STRUCTURE OF STEEL COLUMN AND BEAM ON SEISMIC DESIGN

摘要

Steel column and beam coupling structure suitable for seismic design includes a steel column (10); A steel frame beam (20) transversely connected to the steel column (10); It is disposed between the steel column 10 and the steel beam 20, coupled to the steel column 10 on one side and coupled with the steel beam 20 on the other side, in a direction crossing the longitudinal and longitudinal directions of the steel beam 20. Deformable expansion and contraction bracket (30). The telescopic bracket 30 is a flat part 31 coupled to any one of a steel column 10 and a steel frame beam 20, and is bent in a'c' shape from both ends of the flat part 31, and a'S' type cross section And a flange portion 35 that is bent outward from an end of the elastic portion 35 and the elastic portion 35 and coupled to the other one of the steel column 10 and the steel frame beam 20.
