中文摘要：

就材料性能，几何特征和分析方法的无常而言，演员组 ball-and-socket 支持关节的抵抗的统计参数的分析和可靠性分析被 JC 方法(改进一阶的秒时刻方法) 基于相关试验性的数据执行。结果证明关节的部分因素随可靠性的增加增加的抵抗索引。抵抗部分因素被建议相应于在不同负担联合下面的可靠性索引。而且，建议抵抗部分因素在可靠性设计被采用，并且关节的可靠性索引比目标可靠性索引大，这被发现。最佳的负担联合是实时负担在起一个重要控制作用的那。最后，基于建议抵抗部分因素，一个工程的演员组 ball-andsocket 支持关节的可靠性分析被进行。

英文摘要：

Considering the uncertainty of material performance, geometric characteristic and analysis method, the analysis of statistical parameters of the resistance of cast ball-and-socket support joints and the reliability analysis are carried out by JC method （improved first-order second-moment method） based on the relevant experimental data. Results show that the resistance partial factor of the joint increases with the increase of the reliability index. The resis- tance partial factors are suggested corresponding to the reliability index under different load combinations. Moreover, the suggested resistance partial factor is adopted in reliability design, and it is found that the reliability index of the joint is larger than the target reliability index. The optimal load combination is the one in which live load plays an im- portant control role. Finally, based on the suggested resistance partial factors, the reliability analysis of cast bail-and- socket support ioints of a proiect is conducted.
