Abstract: Super high-rise office building of Jingdong Wisdom City in Suqian City has a structural height of 156.5m. It hasirregularities such as torsional irregularities, discontinuous floor slabs, and offset towers. It adopts concrete-filled steel tubular frame-stiffened steel plate wall and viscous damping wall combined core tube structure system. The full height of the core tube adoptsstiffened steel walls, and a large number of viscous damping walls are used for energy dissipation and shock absorption. The structurewas subjected to vibration analysis, shear model analysis based on equivalent seismic layers, and elastic-plastic time history analysisof rare earthquakes. The analysis results show that the viscous damping wall provides additional damping ratio, which effectivelyreduces the dynamic response of the structure under earthquake action. The steel coupling beams play the role of plastic energydissipation, and the seismic performance of the structure meets the preset target.
