摘要：
In order to provide reference for design and construction of composite box girder with corrugated steel webs(CBCW), test beams were made for fatigue experiment and the typical fatigue failure characteristics were obtained from the experiment. Based on test results and finite element analysis, the comprehensive comparative analysis on similarity of the stress state between steel beam and CBCW was conducted. By fracture mechanics analysis and comparison between the test and finite element analysis results, the fatigue life calculation model was studied and the S-N curves of CBCW were derived. The results show that, for design of CBCW, the category C design standard of the AASHTO 2007 specifications is recommended for finite life fatigue design calculation for safety.
