A new bridge-vehicle system - part II: Parametric study
Chan, Tommy H.T., Yu, Ling, Yung, T.H., & Chan, Jeffrey H.F. (2003) A new bridge-vehicle system - part II: Parametric study. Structural Engineering and Mechanics, 15(1), pp. 21-38.
The formulation of a new bridge-vehicle system using shell with eccentric beam elements has been introduced in a companion paper (Part 1). The new system takes into account of the contribution of the twisting and pitching modes of vehicles to the bridge responses. It can also be used to study the dynamic transverse load distribution of a bridge. This paper presents a parametric study on the impact induced by one vehicle or multi-vehicle running across a bridge using the proposed model. Several parameters were considered as variables including the mass ratio, the speed parameter, the frequency ratio and the axle spacing parameter to investigate their effects on the impact factor. A total number of 189 cases were carried out in this,parametric study. Within the realistic range of vehicle considered, the maximum impact factors could be 2.24, 1.78 and 1.49 for bridges with spans 10m, 20m and 30m respectively.
Impact and interest:
Citation counts are sourced monthly from and 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.
Citations counts from theindexing service can be viewed at the linked Google Scholar™ search.
