Scaling Laws in Progressive Collapse Studies (2024)
Conference Proceeding
Elkady, N., Augusthus-Nelson, L., & Weekes, L. (in press). Scaling Laws in Progressive Collapse Studies.

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.

Sensitivities Of Interfacial Bond-Sip Properties In Predicting The Behaviour Of FRP-Strengthened Concrete (2023)
Conference Proceeding
Augusthus Nelson, L., Weekes, L., & Milani, G. (2023). Sensitivities Of Interfacial Bond-Sip Properties In Predicting The Behaviour Of FRP-Strengthened Concrete. . https://doi.org/10.1007/978-3-031-44603-0_7

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...
