摘要
为了提高军用桥梁的性能,应用可靠性理论对军用桥梁的疲劳抗力和荷载效应进行分析,对8种军用桥梁的疲劳可靠度进行了校准计算。采用加权平均法定出疲劳目标可靠度指标,推导了疲劳设计公式,并给出各分项系数的建议值。计算结果表明,该方法简单易行,可供新一代设计准则的修订时参考。
In order to improve the performance of military bridge,the resistances and loads were analysed by calculating the security level of eight bridges based on the theory of structural reliability. With the method of weighting average,index of goal reliability for fatigue was dealt with. Formula of fatigue design for military bridge was presented. Subentry coefficients were suggested. Theresults show that the method is feasible and applicable in recension of design criterion.
