Projects | Facilities | People
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 Groups
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.

-
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.
