FATIGUE LIFE OF BRIDGES UNDER REPEATED HIGHWAY LOADINGS

THE FATIGUE LIFE OF BRIDGES UNDER REPEATED HIGHWAY LOADING IS DIFFERENT FROM THE USUAL FATIGUE RESEARCH IN LABORATORIES ON MADE UP BRIDGE MEMBERS SUCH AS THOSE PRESENTED IN THE HIGHWAY RESEARCH BOARD REPORT 102. THE FINDINGS HERE ARE IN KEEPING WITH THE LONG TIME OBSERVATION OF THE BEHAVIOR OF PROPERLY DESIGNED AND MAINTAINED BRIDGES UNDER TRAFFIC. THAT IS, SO LONG AS THE WORKING STRESSES DO NOT GREATLY EXCEED THE DESIGN STRESSES, THE FATIGUE PROBLEM IS PRACTICALLY NON-EXISTENT FOR THE NORMAL LIFE OF A PROPERLY DESIGNED BRIDGE. /FHWA/
