Influence of railway loading on the performance of soil-filled masonry arch bridges (2018)
Journal Article
Augusthus Nelson, L., Swift, G., Smith, C., Gilbert, M., & Melbourne, C. (2018). Influence of railway loading on the performance of soil-filled masonry arch bridges. Proceedings of the ICE - Bridge Engineering, 171(4), 276-289. https://doi.org/10.1680/jbren.17.00027

Masonry arch bridges are found in large numbers on the rail networks of Europe and other parts of the world. However, the mode of response of masonry arch structures subjected to railway loading is little understood. To address this, an experimental...

Shear behaviour of lightweight concrete beams strengthened with CFRP composite (2018)
Journal Article
Al-Allaf, M., Weekes, L., & Augusthus Nelson, L. (2019). Shear behaviour of lightweight concrete beams strengthened with CFRP composite. Magazine of Concrete Research, 71(18), 949-964. https://doi.org/10.1680/jmacr.17.00488

This paper presents the experimental results obtained from lightweight and normal concrete beams with closed and U-shaped configurations of epoxy bonded Carbon FRP (CFRP) reinforcement in order to compare the shear resisting mechanisms between lightw...

Long term durability properties of concrete modified with metakaolin and polymer admixture (2018)
Journal Article
Al Menhosh, A., Wang, Y., Wang, Y., & Augusthus Nelson, L. (2018). Long term durability properties of concrete modified with metakaolin and polymer admixture. Construction and Building Materials, 172, 41-51. https://doi.org/10.1016/j.conbuildmat.2018.03.215

Previous studies show that both metakaolin (MK) and polymer can respectively improve certain mechanical and durability properties of concrete. Also, recent studies show that a combination of MK and polymer further enhances the mechanical properties b...

Large-scale physical modelling of soil-filled masonry arch bridges (2017)
Journal Article
masonry arch bridges. International Journal of Physical Modelling in Geotechnics, 18(2), 81-94. https://doi.org/10.1680/jphmg.16.00037

The presence of soil backfill has been shown to have a significant influence on the load-carrying capacity of masonry arch bridges, with the soil fill providing a number of important functions, including inter alia, the distribution of surface load...

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.

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...

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...
