High-performance Steel Structures
High-performance (stainless, high strength and ultra-high strength) steels possess advantageous mechanical properties, superior durability and corrosion resistance, which result in more economic and sustainable design solutions and thus has a greater potential for widespread use in civil and offshore engineering applications. Our group is conducting systematic laboratory tests and numerical modelling on different types of high-performance steel structures (beams, columns, beam–columns, connections, etc.), investigating their mechanical behaviour as well as load-carrying and deformation capacities, and developing improved design rules. Up to date, a number of research findings have been included in Eurocode 3, which indicates both the academic significance and the high impact on industry and real life.

Recycled Aggregate Concrete and Composite Structures
To achieve the 3Rs (Reduce, Reuse and Recycle) of construction and demolition wastes, the use of recycled aggregate concrete (RAC) is becoming popular. However, RAC has lower strength, stiffness and ductility than nature aggregate concrete. Therefore, a new and sustainable composite system – RAC-filled high-performance steel tube is proposed, which is ale to increase the load-carrying capacity to an acceptable level. Our group is conducting a research project aiming at investigating the structural behaviour of different types of RAC-filled high-performance steel tube structural members, verifying their local and global buckling resistances and deriving efficient design approaches.

Fire and Post-fire Behaviour of Steel and Composite Structures
In case of fire, structural members in buildings suffer from serious damages and loss of load-carrying capacities, finally leading to collapse of the whole buildings. Therefore, it is essential to understand the fire and post-fire behaviour of steel and composite structures. Our group is conducting a research project to investigate the material response, cross-section behaviour and member stability of high performance steel and composite structurs subject or after exposure to ISO-834 standard fire for varying heating durations.

Automation in Construction and Artificial Intelligence in Structures
Automation in construction could boost construction productivity and reduce reliance on manpower. Our group is working closely with government agencies and industry collaborators and has developed a new intergrated software DDPC to assist automatic design and interactive data sharing through BIM platform.
Current structures are increasingly irregular, complex and large-size, and therefore becoming hard to accurately predict their behaviour, especially in hazard events. Our group is conducting research on AI-based methods for structural design and analysis. |
