为了保证结构加强层设置的合理与有效,通过工程实例介绍了在超高层建筑中合理设置加强层的思路和方法,对多种可能性做计算分析、判断,最终确定加强层的数量和位置。针对超高层建筑进行了加强层设置屈曲约束支撑的对比分析。分析结果显示,对于高烈度区的罕遇地震,屈曲约束支撑具有一定的滞回性能,可以减小结构地震反应,但减小效果不大。
In order to ensure the reasonable and effective arrangement of the structure strengthening layer, the idea and method of reasonably setting the strengthening layer in the super high-rise building are introduced through examples of engineering. The calculation and analysis of various possibilities are made to determine the number and position of the strengthening layer. Contrastive analysis of buckling restrained support for strengthening floors in super high-rise buildings. The analysis results show that the buckling restrained brace has a certain hysteretic behavior for rare earthquakes in the high intensity region, which can reduce the seismic response of the structure, but the effect is not obvious.
