Abstract
A theoretical investigation of the dynamic impact factors for straight and curved composite cellular bridges is performed in this thesis. The bridges are modelled as three-dimensional solid structures using commercially available software "ABAQUS" to simulate the bridge geometry and vehicle loading. The vehicle loads are modelled as a pair of two concentrated forces moving along in circumferential paths. Extensive parametric study is conducted, in which 120 composite multi-cell bridge prototypes are analyzed to: (1) evaluate their first natural frequencies; (2) evaluate their impact factors for moment, reaction, and deflection under truck loading conditions. The key parameters considered in this study are: number and area of cross-bracing and top-chord systems, number of cells, number of lanes, degree of curvature, span length, and loading conditions. Based on the data generated from the parametric study, expressions for dynamic impact factors for moment, reaction, and deflection are proposed.* (Abstract shortened by UMI.) *This dissertation includes a CD that is compound (contains both a paper copy and a CD as part of the dissertation).
