The 2010-2011 Canterbury (New Zealand) earthquake sequence has highlighted the severe mismatch between societal expectations over the reality of seismic performance of modern buildings.
A paradigm shift in performance-based design criteria and objective towards damage-control or low-damage design philosophy and technologies is urgently required.
The increased awareness by the general public/tenants, building owners, territorial authorities as well as insurers/reinsurers, of the severe economic impacts of moderate-strong earthquakes in terms of damage/dollars/downtime has indeed stimulated and facilitated the wider acceptance and implementation of cost-efficient damage-control, or low-damage, technologies. The ‘bar’ has been raised significantly with the request to fast track the development of what the general public would refer to as the “ultimate” earthquake resisting building system, capable of sustaining the shaking of a severe earthquake basically unscathed.
This presentation will provide an overview of recent advances towards a low-damage building system design. The design approach is developed within an integrated performance-based framework, that accounts for the performance of the skeleton of the superstructure, the non-structural components and the interaction with the soil/foundation system.
Examples of real on site-applications of such technology in New Zealand, using concrete, timber (engineered wood), steel or a combination of these materials, and featuring some of the latest innovative technical solutions developed in the laboratory will be presented. These form examples of the successful transfer of performance-based seismic design approach and advanced technology from theory to practice in line with the broader objective of Building Resilience.
