Dr Ryan Hoult Research Leader

Dr Ryan Hoult’s PhD assessed the performance of reinforced concrete walls in response to rare and very rare earthquakes. Completed in 2017, Ryan’s research analysed both rectangular and C-shaped concrete walls to develop a secondary cracking model to predict the potential of cracks forming in these types of walls. Ryan found that the direction of loading and the mode of bending were particularly important for the seismic performance of these sorts of walls.

Ryan is now a Research Fellow at École Polytechnique Fédérale de Lausanne University in Switzerland. He leads a project working with South American researchers on mitigating earthquake risk, and has noted that South America and Australia have similar issues in regards to a lack of testing on structures to assess their risk.

“Their buildings codes are actually lacking over there (South America) quite surprisingly, considering they get a lot of earthquakes,” Ryan said. “The Australian concrete structures code [AS 3600] has allowed designers to detail reinforced concrete walls with a relatively low amount of reinforcement. This is designed for a relatively low earthquake return period, which has resulted in the reinforced concrete buildings of Australia to be vulnerable to a rare earthquake event.”
