Abstract

This paper investigates the effect of foundation settling on masonry arch bridge structural behaviour using Finite Element Analysis (FEA). Masonry arch bridges form a large proportion of existing European infrastructure such as rail and road bridges. These structures are very robust but can fail for several reasons, principally as a result of excessive compressive or tensile stress or movements of the foundation. Masonry arch bridges operate by transfer of axial compression, and their curved geometry means that their support reactions have horizontal and vertical components. Therefore, the stability of these structures depends on the ability of the foundation to resist horizontal and vertical forces without excessive sliding and settlement respectively. This makes arch foundation movement one of the most prominent reasons for failure. In this study a 3D, single span, voussoir masonry arch bridge is modelled using ABAQUS including the effects of soil-structure interaction and foundation movement. The results of parametric studies are presented and discussed. Validation of structural behaviour is made by comparison with physical testing.
