| 摘 要： | 考虑结构材料强度、几何尺寸以及计算模式的随机性,同时考虑梁纵筋的超强影响,采用可靠度理论分析了钢筋混凝土结构单个节点强柱弱梁设计的可靠度,得出了不同设防等级下强柱弱梁设计的可靠指标以及对应的失效概率．在此基础上,以6层框架为例,分析了不同柱端弯矩增大系数下结构的整体失效概率,采用投资-效益准则,提出了一种合理的确定柱端弯矩增大系数的方法．

| Abstract: | The concrete strength, steel strength, member dimensions and flexure model were considered as random variables, the reliability of "strong column-weak beam design" for one joint of reinforced concrete frame was analyzed under a series of column-to-beam strength ratio, and the failure probability of reinforced concrete frames was also analyzed. Based on those results, the column-to-beam strength ratio was determined. Using the "cost-benefit" criteria, a method for determining column-to-beam strength ration was presented. |
