Behaviour of backfilled masonry arch bridges subjected to cyclic loading (2016)
Presentation / Conference Contribution

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.

A new mitigation scheme to resist progressive collapse of RC structures (2016)
Journal Article

Reinforced concrete structures may be vulnerable to progressive collapse due to lack of sufficient continuous reinforcement. In most guidelines, general structural integrity requirements to reduce progressive collapse have been introduced, but the de...

Progressive collapse resisting mechanisms of reinforced concrete structures (2016)
Presentation / Conference Contribution

Reinforced concrete (RC) buildings may be vulnerable to progressive collapse due to lack of
sufficient continuous reinforcement. Progressive collapse is a situation when local failure is
followed by collapse of adjoining members, which in turn caus... Read More about Progressive collapse resisting mechanisms of reinforced concrete structures.

An experimental investigation into the bond-slip behaviour between CFRP composite and lightweight concrete (2016)
Journal Article

Epoxy bonded fibre reinforced polymer (FRP) composites are widely used for the retrofit of ailing reinforced concrete structures, for both shear and flexure. The behaviour of retrofitted concrete structures is governed by the bond strength and the ma...

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...

Experimental study on bond-sip behaviour between CFRP sheets and lightweight concrete (2015)
Presentation / Conference
Mustafa, A., Weekes, L., & Augusthus Nelson, L. (2015, September). Experimental study on bond-sip behaviour between CFRP sheets and lightweight concrete. Presented at ACIC 2015, Cambridge, UK

Epoxy bonded fibre reinforced polymer (FRP) composites are widely used for the retrofit of ailing reinforced concrete structures, for both shear and flexure. The behaviour of retrofitted concrete structures is governed by the bond and material charac... Read More about Experimental study on bond-sip behaviour between CFRP sheets and lightweight concrete.

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...

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.
