分析了抗震等级分别为一级、二级和三级,并且设防烈度分别为7、8度时的钢筋混凝土框架强柱弱梁设计的保证率,结合强柱弱梁设计功能函数中的各个随机变量的统计特征,分别分析了住宅楼和办公楼在抗震等级为一级、二级和三级时的钢筋混凝土框架强柱弱梁的可靠指标；结合一级抗震等级、9度设防烈度区的框架结构强柱弱梁的可靠指标取值,得出合理的超筋率取值范围.分析结果表明:控制超筋率可以使框架结构强柱弱梁设计得到保障；所得结论为进一步分析可靠指标的最终合理取值范围提供了依据.%Authors analyzed strong column-weak beam design grarantee rates of reinforced concrete frames at the seismic rating of 1, 2 and 3, fortification intensities were 7, 8 degrees associated with various statistical characteristics of random variables in strong column-weak beam design feature function, eachly analyzed residential and office buildings' reliability index of strong column-weak beam of reinforced concrete frames in the seismic rating of 1,2 and 3,combined witha reliability index of strong column-weak beam in the seismic rating of 1,9 degrees fortification intensity areas, found out a reasonable range of super configuration percentage of reinforcement. Analysis results show that controlling super configuration percentage of reinforcement can ensure strong column-weak beam design of reinforced concrete frames. The conclusions provide the bases for further analyzing the reasonable range of the reliability index.
