Leveraging the complimentary expertise of our team in the key areas of materials, structural engineering and computational mechanics we develop a fundamental understanding of the behaviour of components and structures, so that they can be tailored and adapted to meet the demands of an ever-changing society by taking advantage of novel materials and innovative manufacturing techniques.

Research topics

Our research activities cover all aspects of structural engineering including: traditional and innovative construction materials; rehabilitation solutions and novel structural systems; resilient buildings and infrastructure under extreme load events such as earthquakes, blast and impact and fire; computational mechanics and building physics; lightweight and sustainable construction; digital manufacturing and robotics.

Concrete Structures and Materials

Our work covers all aspects of concrete, concrete technology and sustainable solutions, innovative additive construction methods (e.g., 3D concrete printing), Fibre Reinforced Concrete, Fibre Reinforced Polymer strengthening and reinforcements, structural and material testing and characterisation, short and long-term structural behaviour, analysis, innovation, and design.

Steel and Composite Structures

Our current research activities are focussed on cold-formed steel structures considering local stability, joint performance and modelling under fire and dynamic loading, additive manufacturing, structural optimisation, performance-based seismic design, tubular structures, performance of steel composite structures in fire, steel and timber hybrid structures, the role of steel structures in building adaptability, and design for deconstruction and reuse of steel structures.

Fire Engineering

Our research covers structural fire engineering and fire science. We conduct both experimental and numerical work to understand how structures behave in fire and how fire develops. Our current focus is to work toward a harmony between fire safety and sustainability, e.g. investigating the performance of novel sustainable low carbon structural systems and materials in fire.

Intelligent Infrastructure

Research focuses on the development and application of digital design and manufacturing methods and innovative monitoring, sensing and analysis techniques to tackle current and future challenges in the field of constructed infrastructure. The aim is to enhance productivity and sustainability, working in close collaboration with practitioners responsible for the design, construction, operation and maintenance of buildings, bridges and other constructed infrastructure. The Intelligent Infrastructure group is affiliated to the Integrated Civil and Infrastructure Research (ICAIR) Centre, which provides excellent facilities for large-scale testing of concrete, masonry, steel and timber components and structures.
