| Abstract: | Research purposes: Limit states design method based on reliability theory is the trend of development for the design code in railway engineering structures,and the target reliability index is an important part among it.With the rapidly development of railway industry,the basic conditions of the original calibrate value have partly changed,which requires analysis of target reliability index for steel railway bridges' ultimate limit states under the new situation. Research conclusions: Under the new situation... |
