Abstract: The 1# tower of Guangzhou Science City Center has irregularities of corner overlapping and irregular facadesetback. The influence of the stiffness of the lower corewall on the overall performance of the structure was compared andanalyzed, and the change law of the internal force and the response index of the corner overlapping area, the high tower partwith façade setback and the overall structure were studied. The results show that the weak structural stiffness scheme isadopted for the low tower part in the overlapping façade setback area to provide better structural seismic performance.

Keywords:Guangzhou Science City Center; corner overlapping; facade setback; seismic performance; complex high-rise building
