摘要:
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。
Abstract:
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 with a reliability index of strong column-weak beam in the seismic rating of 1,9 degreesfortification 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.
