Abstract:The No-1 building of Huaqiang Gold Corridor City Square in Shenyang is a mixed structural system of frame-corewall with the structural height of 300m. The outer frame is composed of concrete filled steel tubular columns and steel beams, and corewall is composed of reinforced concrete shear wall. Combined with the features of spindle-shaped architectural appearance and circular plane, three pieces of belt trusses were arranged in the outer frame, and built-in steel tubes were set in shear walls of the bottom strengthening zone, to solve the problem of lateral stiffness of super high-rise structure and ductility of shear wall. Special analyses of the structure were conducted including the elastic analysis, elastic-plastic analysis, key nodes analysis and concrete creep analysis, and corresponding strengthening measures were taken to make the structure meet the requirements of seismic performance objectives.
Keywords:super high-rise structure; concrete filled steel tube composite shear wall; spindle-shaped building; seismic performance; belt truss; creep analysis
