Effectiveness of repair on damaged reinforced concrete components - Alex Shegay
Understanding the effects of repair on reinforced concrete structures is critical for evaluating their performance in future earthquakes. This presentation provides an overview of a coordinated body of research conducted over the past five years on the seismic performance of repaired reinforced concrete systems. The discussion focuses on performance recovery observed in both system-level and component-level studies, and examines the implications of these findings for practical repair strategies.
The collapse potential of unreinforced masonry structural components - Anastasios Giouvanidis
The presentation reports experimental findings from a recent campaign on scaled unreinforced masonry walls. Two prevalent collapse mechanism configurations are employed to investigate their seismic performance and failure potential when subjected to pulse-type and recorded ground motions. The presentation summarises results from over 500 shaking table and free-vibration tests, with emphasis on overturning spectra and the identification of experimentally informed limit states and fragility curves.
Resilient mass timber structures: a full-scale study - Ashkan Hashemi
This presentation presents the design and full-scale experimental testing of a resilient two-storey Cross-Laminated Timber (CLT) structure incorporating rocking wall systems and tension-based bracing as the primary lateral load-resisting mechanisms. Recently completed at the University of Auckland, the testing programme investigated different approaches to lateral load transfer and energy dissipation across multiple loading scenarios. The results demonstrate the potential for mass timber systems to achieve performance beyond life safety, targeting immediate occupancy and full functionality after seismic events, while remaining practical, sustainable, and cost-effective for real-world application.
On behalf of the Engineering for Natural Hazard Mitigation Research Centre at the University of Auckland, we are pleased to present three talks showcasing distinct areas of ongoing research.
