Proposed permissible limit state assessment criteria for masonry arch bridges (2016)
Presentation / Conference
Gilbert, M., Melbourne, C., Smith, C., Augusthus Nelson, L., & Swift, G. (2016, October). Proposed permissible limit state assessment criteria for masonry arch bridges. Presented at ARCH '16. Proceedings of the 8th International Conference on Arch Bridges, Wroclaw, Poland

The Ultimate Limit State (ULS) is commonly used when assessing masonry arch bridges. Traditionally one or more, relatively large, partial factors are applied to the ULS to determine the level of service loading that can be safely applied to a given b...

Behaviour of backfilled masonry arch bridges subjected to cyclic loading (2016)
Presentation / Conference
Augusthus Nelson, L., Swift, G., Smith, C., Gilbert, M., & Melbourne, C. (2016, October). Behaviour of backfilled masonry arch bridges subjected to cyclic loading. Presented at 8th International Conference on Arch Bridges, Wrocław, Poland

Experimental research has demonstrated that the interaction between soil fill surrounding the arch barrel of a masonry arch bridge structure has a significant influence on ultimate limit state behaviour. However, little work has been carried out to... Read More about Behaviour of backfilled masonry arch bridges subjected to cyclic loading.

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...

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.
