Theoretical assessment of progressive collapse capacity of reinforced concrete structures (2016)
Journal Article
Alogla, K., Weekes, L., & Augusthus Nelson, L. (2017). Theoretical assessment of progressive collapse capacity of reinforced concrete structures. Magazine of Concrete Research, 69(3), 145-162. https://doi.org/10.1680/jmacr.16.00319

The progressive collapse behaviour of reinforced concrete (RC) structures requires consideration of material and geometric non-linearity, concrete crushing and rebar fracture. Compressive arch action (CAA) and catenary action (CTA) are the main res... Read More about Theoretical assessment of progressive collapse capacity of reinforced concrete structures.

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.

A new mitigation scheme to resist progressive collapse of RC structures (2016)
Journal Article
Alogla, K., Weekes, L., & Augusthus Nelson, L. (2016). A new mitigation scheme to resist progressive collapse of RC structures. Construction and Building Materials, 125, 533-545. https://doi.org/10.1016/j.conbuildmat.2016.08.084

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
Alogla, K., Weekes, L., & Augusthus Nelson, L. (2016, July). Progressive collapse resisting mechanisms of reinforced concrete structures. Presented at New Trends on Integrity, Reliability and Failure, Porto/Portugal

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...

An experimental investigation into the bond-slip behaviour between CFRP composite and lightweight concrete (2016)
Journal Article
Mustafa, A., Weekes, L., Augusthus Nelson, L., & Leach, P. (2016). An experimental investigation into the bond-slip behaviour between CFRP composite and lightweight concrete. Construction and Building Materials, 113, 15-27. https://doi.org/10.1016/j.conbuildmat.2016.03.032

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...
