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.

Influence of the span rise ratio on the capacity of masonry arch bridges (2014)
Presentation / Conference
Donaghy, J., Wang, J., & Augusthus Nelson, L. (2014, July). Influence of the span rise ratio on the capacity of masonry arch bridges. Presented at 9th International Masonry Conference, Guimarães, Portugal

Current standards promote a holistic approach in appraisal of masonry arch bridges. This is derived from the aspect of a perfect arch with specific span rise ratios. The MEXE (Military Engineering Experimental Establishment) method used as first stag... Read More about Influence of the span rise ratio on the capacity of masonry arch bridges.

Physical modelling of cyclically loaded masonry arch bridges (2013)
Presentation / Conference
Swift, G., Augusthus Nelson, L., Melbourne, C., & Gilbert, M. (2013, October). Physical modelling of cyclically loaded masonry arch bridges. Presented at 7th International Conference on Arch Bridges, Trogi-Split, Croatia

Experimental work involving large-scale physical models of backfilled masonry arch bridges is being undertaken to examine the behaviour of these structures under cyclic loading regimes. The aim of this research is to better understand the relationshi... Read More about Physical modelling of cyclically loaded masonry arch bridges.
