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.
