Scope

Main technical content: This specification is divided into 7 chapters and 1 appendix. The main technical content includes: General Provisions, Terminology and Symbols, Basic Provisions, Design of Composite Column Frame, Design of Steel Tube Concrete Shear Walls, Connection Design, and Construction and Acceptance of Structures. The main technical content revised in this specification includes: 1. The maximum applicable height of composite columns; 2. Determining the design values of bending moments at the ends of composite column frames and shear forces in composite columns and frame beams using the actual reinforcement method; 3. Deducting the shear strength of steel tubes when checking the minimum shear resistance section of composite columns and steel tube concrete shear walls, and considering the shear strength of steel tubes when calculating the shear bearing capacity; 4. Calculating the shear bearing capacity of central cross-sections of eccentrically compressed composite columns; 5. Calculating the axial compression ratio of composite columns; 6. Arranging stirrups in the reinforcing zone of composite columns; 7. Calculating the axial compression bearing capacity of steel tube concrete shear walls; 8. Calculating the shear bearing capacity of inclined cross-sections of eccentrically compressed and eccentrically tensile steel tube concrete shear walls; 9. Calculating the axial compression ratio and limiting values of steel tube concrete shear walls; 10. Seismic construction measures for composite columns and steel tube concrete shear walls; 11. Connecting reinforced concrete beams with composite columns; 12. Designing the foot of composite columns; 13. Construction and acceptance of composite column structures.
