TY - JOUR PY - 2019// TI - The identification technology of vehicle weight based on bridge strain time-history curve JO - Advances in structural engineering A1 - Hao, Tianzhi A1 - Xie, Zhengyuan A1 - Yu, Mengsheng SP - 1606 EP - 1616 VL - 22 IS - 7 N2 - It is the basic characteristics of bridge weigh-in-motion technology to directly identify the vehicle weight based on the bridge dynamic response. At present, bridge weigh-in-motion technology tends to be mature in identification of gross vehicle weighing, but there is no breakthrough in identification of single-axle weighing. Therefore, a new axle-weight identification method is proposed using bridge weigh-in-motion technology in this article, in which the idea of bridge weigh-in-motion technology is introduced first. The numerical expression of the single-axle weight and the identification expression of axle space and vehicle speed are presented thereafter. Furthermore, the accuracy of the presented method is further reinforced through a series of practical model experiments of simply supported and continuous beam. The experimental result indicated that the proposed method is feasible in practical application.
