Researchers from our department are contributing to a new four-year University Research Programme titled, "Right-Sized Retrofit: Cost-Effective Seismic Strengthening for Vulnerable Concrete Buildings," funded by the Natural Hazards Commission Toka Tū Ake, exploring more cost-effective approaches to strengthening vulnerable concrete buildings.
Professor Santiago Pujol and Dr Ke Jiang from UC Civil and Environmental Engineering are associate investigators on the programme, alongside Dr Alex Shegay and Dr Lucas Hogan from the University of Auckland, with UC postdoctoral researcher Dr Cesar Pajaro also contributing.
The research builds on a growing body of work focused on improving the seismic resilience of existing reinforced-concrete buildings in Aotearoa New Zealand.
Professor Pujol has previously led NHC-funded research into developing practical retrofit guidance for existing reinforced-concrete multi-storey buildings, including work with researchers such as Dr Hogan and Dr Shegay. The research highlighted the importance of identifying and prioritising critical vulnerabilities and ensuring that retrofit solutions address the actual needs of a building.
More recently, members of the new research team have been involved in research following the 2024 Hualien earthquake in Taiwan, examining the performance and cost of different retrofit approaches in reinforced-concrete buildings. Dr Jiang has also contributed to research examining lessons from the earthquake for the functional recovery of buildings and community resilience.
The new programme will build on this wider research to investigate how seismic strengthening can be appropriately targeted to vulnerable concrete buildings, with a focus on solutions that are both effective and practical.
For UC Civil and Environmental Engineering, the programme provides another opportunity to contribute to research aimed at improving the resilience and long-term performance of Aotearoa New Zealand's built environment.
