摘要]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。

Abstract: For the purpose of insuring the rationality and effectiveness of setting strengthened story, the thinking and method to set the stiffening layer in super high-rise building were introduced with an actual project. The calculation and analyses were needed to determine the amount and the location of the strengthened story. The comparative analysis of using buckling restrained brace in strengthened story of super high-rise building was carried out. And the results of the analysis show that when using the buckling restrained brace in rarely occurred earthquake of highly seismic region, there is some hysteretic behavior in it, and can minimize the earthquake response but is not so effective.
Keywords: super high-rise building; strengthened story; buckling restrained brace
