摘　　要：广州科学城中心1#塔楼同时存在角部重叠与体型收进不规则项,对比分析了低塔区域核心筒刚度强弱对结构整体性能的影响,并针对角部重叠区、收进后高塔部分及整体结构的内力及响应指标变化规律进行了研究,结果表明重叠收进区域低塔区域采用弱结构刚度方案,结构抗震性能更优。The 1# tower of Guangzhou Science City Center has irregularities of corner overlapping and irregular facade setback. The influence of the stiffness of the lower corewall on the overall performance of the structure was compared and analyzed, and the change law of the internal force and the response index of the corner overlapping area, the high tower part with fa9 ade setback and the overall structure were studied. The results show that the weak structural stiffness scheme is adopted for the low tower part in the overlapping fa9 ade setback area to provide better structural seismic performance.
