Abstract:Heji International Building is 178-8 meters tall and is classified as a B-grade high-rise building that exceeds height requirement of specifications. It adopts mixed structural system of concrete filled steel tubular column, steel reinforced concrete beam and reinforced concrete corewall. The tower building in this project has a concave-convex architecture plane with many edges. The frame columns are arranged unevenly, and there are multiple irregularities including torsion irregularity, discontinuous floor, concave-convex irregularity and complex structural connections. The foundation and basement design was introduced and it focused on the frame-corewall structural system design, complex connecting body design, new type CFST columns joint design, cross ribbed plate design and built-in cavity and multi-cavity U-shaped steel wrapped concrete composite beam. Two programs of YJK and MIDAS Building were used to conduct the regular elastic static analysis and elastic dynamic analysis under the frequent earthquake, and elastic analysis and non-yielding calculation under the fortification earthquake were supplemented. And elastic-plastic dynamic time-history analysis under the rare earthquake was carried out by SAUSAGE program. Finally, the measures taken to strengthen the regularities of the project were put forward.
Keywords:frame-hollow corewall； new type CFST column joint； cross ribbed plate； built-in cavity and multi-cavity U-shaped steel wrapped concrete composite beam
