Calculating an Influence Line from Direct Measurements (2006)

Abstract The response of a bridge to a pre-weighed truck can bemeasured on site. This paper describes a mathematicalmethod for converting the measured response of a loadeffect into an influence line for that effect. One influenceordinate is calculated for each scan of the data acquisitionsystem. The vector of ordinates is found by solving a largeset of simultaneous equations expressed in matrix form.The general form of the matrices is described, and theparticular matrices for a three-axle truck are given.The technique is demonstrated using measured strainon two bridges using pre-weighed trucks with differentnumbers of axles.
