摘要
本文给出了铁路钢桁梁竖向刚度正常使用极限状态可靠度的评估方法，并结合具体算例证实了该方法的可行性，计算和比较了既有的18座铁路钢桁梁的竖向刚度正常使用极限状态的隐含可靠指标。
The method of evaluating the reliability of steel railway trusses in serviceability limit State on vertical rigidity is given in this paper. With a speific example,the feasibility of this method is confirmed. The latent safety indexes of 18 pices of steel railway trusses in serviceability limit state on their vertical rigidity are calculated and compared.
