TRUCK MOMENT RANGE FROM SINGLE CONCENTRATED LOAD

It is noted that the range in bending moment caused by the recently recommended (Guide Specifications 1990) fatigue design truck may be determined, for both preliminary design purposes and detailed checking, by using the series of moment-ratio coefficients presented here. The method applies to symmetrical bridges with relatively uniform stiffness. One strucutral analysis is required to determine the moment caused by a single placement of the fatigue truck's resultant concentrated load, and this result is transformed to the moment range caused by the passage of the truck. It is possible to determine bending moment range by employing basic bridge design aids, such as influence ordinates for bending moment.
