Flexible pavements are subjected to three main distress types: fatigue crack, thermal crack, and permanent deformation. Under severe climate conditions, thermal cracking particularly contributes largely to a considerable scale of premature deteriorat...

Size effects in unreinforced and lightly reinforced concrete beams failing in flexure (2021)
Journal Article

Fracture-based models commonly use a characteristic length as the basis for
determining size effects in concrete beams. The characteristic length is related
to the concrete fracture process zone and defined in terms of the concrete fracture propert... Read More about Size effects in unreinforced and lightly reinforced concrete beams failing in flexure.

Analytical modelling of bond-slip failure between epoxy bonded FRP and concrete substrate (2020)
Journal Article

In this paper, a set of explicit theoretical derivations from a generalised
bond-slip model for an epoxy bonded fibre reinforced polymer (FRP) sheet
to concrete are presented. The derivations address the maximum bond resistance, load-slip response,... Read More about Analytical modelling of bond-slip failure between epoxy bonded FRP and concrete substrate.

Experimental & numerical simulation of soil boundary conditions under dynamic effects (2018)
Presentation / Conference
Qaftan, O., Weekes, L., Toma-Sabbagh, T., & Augusthus Nelson, L. (2018, June). Experimental & numerical simulation of soil boundary conditions under dynamic effects. Presented at 16th European Conference on Earthquake Engineering (16ECEE), Thessaloniki, Greece

When conducting earthquake simulation tests, one of the main concerns is the modelling of boundary effects created by artificial boundaries of a soil model container. The function of this soil container is to hold the soil in place during the excitat... Read More about Experimental & numerical simulation of soil boundary conditions under dynamic effects.

Shear behaviour of lightweight concrete beams strengthened with CFRP composite (2018)
Journal Article

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... Read More about Progressive collapse resisting mechanisms of reinforced concrete structures.

Biomimetic approach for the creation of a deployable structure based on the blooming of the Morning Glory flower (2015)
Presentation / Conference
Fenci, G., Currie, N., & Weekes, L. (2015, August). Biomimetic approach for the creation of a deployable structure based on the blooming of the Morning Glory flower. Presented at International Association for Shell and Spatial Structures (IASS) Symposium 2015 : Future Visions, Amsterdam, The Netherlands

This research project proposes the design of a freestanding, biomimetically inspired, deployable canopy. Nature inspires the structure in terms of mechanism and shape, allowing for the creation of a lightweight, multifunctional, and efficient deploya...
