These research problems are related to a variety of areas in the engineered and natural environment eg building ventilation, reservoir water quality and both near-shore and coastal ocean engineering.

Structural Engineering

Structural engineers design and supervise the construction of a wide range of structural forms including buildings, bridges, dams, towers, off-shore oil and gas platforms, tanks and silos. Structural engineering techniques are also used in the design of mine shafts, tunnels and large underground chambers to provide facilities such as car parks or power stations.
Research activities in structural engineering are both analytical and experimental in nature and are directed at investigations into:
Bending, buckling and dynamic behaviour of fibre-reinforced composite plates;
Strength of concrete-filled steel tubular beams and columns;
Rehabilitation and retrofitting of timber, steel and concrete structural members by advanced composite jacketing;

Reliability assessment of existing structures subject to deterioration;
Analysis and assessment of concrete bridges;
The analytical work relies heavily on the use of modern computer techniques.

Wind Engineering

A strong interest in the engineering aspects of tropical cyclones has been developed within the school. A major aspect of this work is the design of buildings, particularly housing, to resist strong winds. It involves wind tunnel measurements, structural testing and analytical studies and is undertaken in collaboration with the James Cook Cyclone Structural Testing Station, a special research and development unit located within the School. Specific areas of research include:
Wind tunnel measurement of wind forces on structures and wind velocity fields;
