This paper describes a mathematical method for converting the measured response of a load effect into an influence line for that effect. One influence ordinate is calculated for each scan of the data acquisition system. The vector of ordinates is found by solving a large set of simultaneous equations expressed in matrix form. The general form of the matrices is described, and the particular matrices for a three-axle truck are given. The technique is demonstrated using measured strain on two bridges using pre-weighed trucks with different numbers of axles. | Type of material: | Journal Article | Publisher: | Institution of Civil Engineers | Journal: | Bridge Engineering, Proceedings of the Institution of Civil Engineers | Volume: | 159 | Issue: | BE1 | Start page: | 31 | End page: | 34 | Copyright (published version): | 2006, ICE Publishing Ltd | Keywords: | Bridge; Influence line; WIM | Language: | en | Status of Item: | Peer reviewed |
