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.

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...
