Static analysis of masonry arches (2017)
Thesis
Ahmad, S. Static analysis of masonry arches. (Thesis). University of Salford

The aim of the present research was to provide a practical theoretical model based on elementary statics, for assessment for masonry arch bridges, that benefits from the large scale experimental programme at Salford University, together with insight...

Large-scale physical modelling of soil-filled masonry arch bridges (2017)
Journal Article
masonry arch bridges. International Journal of Physical Modelling in Geotechnics, 18(2), 81-94. https://doi.org/10.1680/jphmg.16.00037

The presence of soil backfill has been shown to have a significant influence on the
load-carrying capacity of masonry arch bridges, with the soil fill providing a number of
important functions, including inter alia, the distribution of surface load... Read More about Large-scale physical modelling of soil-filled masonry arch bridges.

Two-dimensional experimental and numerical modelling of a soil-filled masonry arch (2015)
Book Chapter
Ahmad, S., Augusthus Nelson, L., & Swift, G. (2015). Two-dimensional experimental and numerical modelling of a soil-filled masonry arch. In Geotechnical Engineering for Infrastructure and Development: XVI European Conference on Soil Mechanics and Geotechnical Engineering. ICE Publishing

The ultimate load carrying capactiy of soil-filled masonry arches is significantly higher than that of bare masonry arches. The soil fill has a stabalising effect on the masonry arch, distributing the live load and providing passive resistance to def...

Discontinuous analysis of soil-arch interaction in masonry arch bridges (2014)
Presentation / Conference
Ahmad, S., Swift, G., & Augusthus Nelson, L. (2014, July). Discontinuous analysis of soil-arch interaction in masonry arch bridges. Presented at 9th International Masonry Conference, Guimarães, Portugal

Back-filled masonry arches behave in a discontinuous manner, where deformation is governed by interaction at joints and the soil-masonry interface. A discrete element approach is used in order to explicitly model the interactions at discontinuities.... Read More about Discontinuous analysis of soil-arch interaction in masonry arch bridges.

Residual capacity of damaged masonry arch bridges subjected to cyclic loading (2014)
Presentation / Conference
Augusthus Nelson, L., & Swift, G. (2014, July). Residual capacity of damaged masonry arch bridges subjected to cyclic loading. Presented at 9th International Masonry Conference, Guimarães, Portugal

In order to assess the stability of damaged arch structures, the residual capacity of damaged arch bridges needs to be established. This paper reports on two full-scale masonry arches, back-filled with crushed limestone, that were tested up to failur...
