Application of finite element methods to model masonry arch bridges

Describes and shows analysis techniques for 2D modelling of cracking and crushing in arches, investigating ring separation, and modelling repairs using dowels in arches to aid with general bridge management. Soil-stucture interaction modelling is discussed prior to showing how 3D solid models and layered shell elements can be used in conjunction with a trilinear soil model to investigate more detailed models that may also include internal spandrel walls. Paper presented at the 40th IABSE Symposium (Nantes 2018), Nantes, France, 19-21 September 2018 by Philip Icke and Steve Rhodes of LUSAS.
