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.

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...

Sustainable high-performance concrete using metakaolin additive and polymer admixture : mechanical properties, durability and microstructure (2019)
Presentation / Conference Contribution

In recent years, there has been a growing interest in the use of supplementary cementitious materials and polymers to produce high-performance concrete. This paper shows the results of a study on the effect of metakaolin and polymer admixture on mech...

Use of finite element analysis to investigate the structural behaviour of masonry arch bridges subject to foundation settlement (2018)
Presentation / Conference Contribution

This paper investigates the effect of foundation settling on masonry arch bridge structural behaviour using Finite Element Analysis (FEA). Masonry arch bridges form a
large proportion of existing European infrastructure such as rail and road bridges... Read More about Use of finite element analysis to investigate the structural behaviour of masonry arch bridges subject to foundation settlement.

Behaviour of backfilled masonry arch bridges subjected to cyclic loading (2016)
Presentation / Conference Contribution

Experimental research has demonstrated that the interaction between soil fill surrounding
the arch barrel of a masonry arch bridge structure has a significant influence on ultimate
limit state behaviour. However, little work has been carried out to... Read More about Behaviour of backfilled masonry arch bridges subjected to cyclic loading.

Progressive collapse resisting mechanisms of reinforced concrete structures (2016)
Presentation / Conference Contribution

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.
