This paper presents a method for transforming results, obtained from a conventional 2-D linear elastic finite element model of an arch, to a more useful form involving thrust lines between elements. The method is based on resolution of nodal forces, and is controlled by local variations of topological and statical variables. An example is presented for a study of a mediaeval pointed arch with two rings. Thrust line solutions so obtained are considered in the context of a more general limit analysis.
