| 摘 要： | 本文利用有限元软件ETABS对一栋58层的框筒结构进行计算分析，探讨了单独设置环带对超高层建筑位移、自振周期、刚度比以及内力的影响。通过对比这些数据，找出设置一层环带、二层环带以及多层环带的理想位置。最后，可以得出在抗震设防烈度较低且风荷载较小的地区，完全可以通过设置环带使结构满足规范的各项要求的结论。

| Abstract: | The finite element analysis software ETABS was used to analyze a 58-story frame tube structure. The effect of the displacement, natural vibration period, the ratio of lateral stiffness to gravity and internal force to super high-rise building with separate belt were discussed. By comparing the data, the perfect position of one belt, two belts and several belts were obtained. Finally it is concluded that structure can meet normative requirements by setting belt in the seismic fortification intensity and wind load smaller area. |
