Derivation of experimental debonding outputs for FRP-strengthened concrete samples through a fracture energy-based closed form approach (2025)
Journal Article

Numerous bond-slip models have been proposed in the literature to elaborate on the behaviour between concrete and FRP. However, in most of these bond-slip models, the interfacial debonding fracture energy of the bond is not explicit. Furthermore, the...

Equilibrium-based Approach To Establish Hinge Locations In Single-span Back-filled Masonry Arch Bridges Under Arbitrary Surcharge (2024)
Presentation / Conference Contribution

The assessment of masonry arches has gained significant importance due to the substantial reliance of transportation infrastructure on historic structures. Over the past few decades, there has been a discernible shift in the focus towards understandi...

Sensitivities Of Interfacial Bond-Sip Properties In Predicting The Behaviour Of FRP-Strengthened Concrete (2023)
Presentation / Conference Contribution

The performance of FRP-bonded concrete is heavily influenced by the properties of the bond between the two materials. Various bond-slip models incorporating interfacial bond properties have been developed to understand and predict this behaviour. In...

Generalised analytical solutions for linear and non-linear bond-slip models for externally bonded FRP to a concrete substrate (2023)
Journal Article
Augusthus Nelson, L., Weekes, L., Milani, G., & Al-Allaf, M. (2024). Generalised analytical solutions for linear and non-linear bond-slip models for externally bonded FRP to a concrete substrate. Engineering Structures, 298, https://doi.org/10.1016/j.engstruct.2023.117025

This article presents a set of novel analytical derivations from generalised bond-slip models using first principles, which can be used to predict experimental outcomes, including maximum load resistance, load-slip response, and strain throughout the...

Size effects in unreinforced and lightly reinforced concrete beams failing in flexure (2021)
Journal Article
Augusthus Nelson, L., Lees, J., & Weekes, L. (2022). Size effects in unreinforced and lightly reinforced concrete beams failing in flexure. Engineering Fracture Mechanics, 259, 107987. https://doi.org/10.1016/j.engfracmech.2021.107987

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.
