Abstract

The parameters of both vehicle and bridge play an important role in moving force identification. This paper aims to investigate the effect of various parameters on Time Domain Method (TDM) and Frequency- Time Domain Method (FTDM). For this purpose, a steel bridge model and a vehicle model were constructed in laboratory. Bending moment and acceleration responses of the bridge were simultaneously measured when the model vehicle moved across the bridge at different speeds. The moving forces were identified using the TDM and FIDM and rebuilt responses were calculated from the identified forces for comparison of identification accuracy. Assessment results show that both the TOM and FTOM are effective field acceptable with higher accuracy but the TDM is better than the FTOM. Further work includes enhancement of the two methods and merging them into a Moving Force Identification System (MFIS).

Citation countsare sourced monthly from Scopus and Web of Science® citation databases.

These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
