Professor Hoult’s research interests include the use of fibre reinforced polymers for retrofitting and reinforcing of concrete structures, testing and modeling of reinforced concrete and structural health monitoring. One of the challenges faced by society as a whole is how to use resources more efficiently and effectively. Reducing CO2 production is an important aspect of this challenge but as structural engineers our goal should be to optimize the use of resources. Two ways to do this are to build more efficient structures and to extend the lives of existing structures.
FRP has the potential to allow designers to create more efficient new structures as well as enhancing the capacity of existing structures to extend their lives. Professor Hoult’s research investigates how FRP reinforced and retrofitted structures can be modeled accurately so as to be able to optimize design. This involves a combination of both short and long-term experimental programs as well as numerical modeling.
Structural health monitoring (SHM) is often viewed as a solution only in a limited number of cases for structures in distress. However with recent advances in wireless sensor networks (WSNs) as well as fibre optic sensing have the potential to allow for pervasive monitoring. These systems could give engineer the data required to both keep existing structures in service longer and to optimize the design of new structures. Professor Hoult’s research into this area looks at the use of WSNs for long-term monitoring of existing structures as well as the development of new sensors and analysis techniques. The use of fibre optic sensors to determine distributed strain profiles and overall structural performance is another area of ongoing interest.

Professor Hoult will be teaching CIVL 231(Solid Mechanics II) and CIVL 431 (Infrastructure Rehabilitation) in the Winter term. CIVL 231 builds upon fundamental courses in mechanics and deals with concepts such as Mohr’s circle and virtual work. CIVL 431 investigates the reasons for rehabilitation including increased demand, deterioration and extreme events as well as potential techniques for rehabilitation such as retrofitting and monitoring.
