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...

Scaling Laws in Progressive Collapse Studies (2024)
Presentation / Conference Contribution
This state-of-the-art study introduces an innovative approach employing scaling laws to facilitate the utilisation of small-scale models in progressive collapse experimentation. It evaluates the quasi-static behaviour of scaled beam-column sub-assemb... Read More about Scaling Laws in Progressive Collapse Studies.
Unveiling the potential of scaling in progressive collapse studies (2024)
Presentation / Conference Contribution
Progressive collapse: Past, present, future and beyond (2024)
Journal Article
The world has seen a surge in rigorous study efforts on the progressive collapse of structures in the past few decades. These events have led to new standards and provisions in building codes of practice, many of which are still bei... Read More about Progressive collapse: Past, present, future and beyond.
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...

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

Engineering Fracture Mechanics, 259, 107987. https://doi.org/10.1016/j.engfracmech.2021.107987Fracture-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.
