The Assessment of Masonry Arch Bridges—The Effects of Defects

  • Clive Melbourne

Abstract

A large number of the existing stock of masonry arch bridges in the UK suffer from a variety of defects. The paper considers two of these defects—ring separation and spandrel wall separation. Ring separation in multi-ring arches is the loss of bond between successive rings. A series of laboratory tests on 1, 3 and 6 m span arch bridges is described. The significance of soil/structure interaction is discussed and the importance of defects quantified. The relative importance of the various parameters influencing the mode of behaviour and strength of the arch is discussed, thus allowing the engineer to formulate a mathematical model of the arch bridge to be assessed.
