Abstract:China Southern Airlines Building adopts a frame-corewall structural system of prefabricated steel composite members. In order to meet the requirements of building function and seismic performance, steel box-enclosed concrete  shear wall is used in the corewall. The key design techniques of concrete filled steel box shear wall were mainly introduced, including bearing capacity calculation, construction measures, typical joint connections and fire prevention measures. Using ABAQUS software, finite element simulation analysis of the axial compression performance and bending performance of concrete filled steel box shear wall was carried out, and the mechanical performance of high strength reinforced concrete shear wall was compared. The influences of steel box transverse rib spacing, shear span ratio and axial compression ratio on the bearing capacity of concrete filled steel box shear wall were analyzed. The analysis results show that the concrete filled steel box shear wall has high ultimate bearing capacity, good ductility, strong energy dissipation capacity and excellent seismic performance.

Keywords:concrete filled steel box shear wall; super high-rise structure; mechanical property; joints connection; fire prevention measure
