REPEATED STRESSES IN HIGHWAY BRIDGES

A METHOD FOR PREDICTING THE FREQUENCIES OF VARIOUS LEVELS OF STRESS TO WHICH VARIOUS MEMBERS OF HIGHWAY BRIDGES MAY BE SUBJECTED AS A RESULT OF INDIVIDUAL OR VEHICLE GROUP LOADS ENCOUNTERED IN THE VARIOUS COMPOSITIONS AND VOLUMES OF TRAFFIC FOR GIVEN PERIODS OF TIME OR THROUGHOUT THE LIFE OF A GIVEN STRUCTURE IS BEING DEVELOPED. THIS METHOD WILL BE USED IN THE DESIGN CRITERIA FOR FATIGUE OF HIGHWAY BRIDGES THE PROPOSED METHOD TAKES INTO ACCOUNT'THE FREQUENCY DISTRIBUTION OF HEAVY TRUCK LOADS MEASURED IN TERMS OF THEIR H-EQUIVALENCIES ON VARIOUS SPANS, THE LATERAL PLACEMENT OF VEHICLES IN HIGHWAY TRAFFIC, AND THE RELATIVE FREQUENCIES OF THE STRESS-PRODUCING EFFECTS OF THESE LOADINGS AT ANY SELECTED POINT IN A GIVEN BRIDGE.
