Areas of expertise My research integrates theories for nonlinear behaviours of structures, algebraic analysis, numerical computations and laboratory experiments incorporating novel instrumentation layouts. This approach is used to provide penetrative insights into the complex behaviours under load of composite structures, namely structures comprising components of different materials connected to each other. I developed a nonlinear finite element programme for analysis of composite structures. Key features of the programme include:

-Special element for nonlinear behaviour of both discrete and continuous connections.
-Models for nonlinear behaviours of materials (e.g. cracking of concrete, plasticity of steel).
-Techniques to stabilise computations in nonlinear regimes of behaviour.
-Ability to model different types of composite structure.

A key research theme of mine is the uses of (commonly carbon or glass) fibre reinforced polymers (FRPs) to strengthen existing bridges and buildings. Relative to traditional construction materials, FRPs exhibit significant advantages including corrosion resistance, superior strength-to-weight ratios and superior stiffness-to-weight ratios.
