- Synopsis
- RCS Structure is mixed in which columns and beams are composed of different structural materials. Reinforced concrete structure with strong compressive force is used for the columns, and H-shaped steel with excellent cross-sectional performance is used for the beams, making it possible to reasonably construct a frame with a relatively large span. In the beam-column joint where different structural materials intersect, the stress transfer mechanism between the members is complicated, and the design method is characteristic. In February 2021, the Architectural Institute of Japan published the “Design of Mixed Structures Composed of Reinforced Concrete Columns and Steel Beams” for good dissemination of RCS structure. This paper introduces the outline of the guideline.
