Email FP4 Leader

This flagship will seek a new design paradigm whereby reparability and damage-control is explicitly considered in the design process. This requires the development of new low-damage systems, quantification of the reparability (cost and time) of conventional systems, and design process methodologies for implementation. This flagship will also result in important changes to implementation standards; which provide the mainstream technology transfer mechanism given that all future designs must satisfy these standards. Significant economic benefits are also expected through both reductions in future earthquake losses and increased international competitiveness of New Zealand engineering consultants and marketing of new seismic protective devices.

 

Key Thrust Areas

 
 

1: New technologies for buildings

Development of new technologies for buildings (structural and non-structural) to control damage in future events and enable rapid recovery.

    • Deliverable 1.1: 100%
      • Develop low damage systems for buildings (with focus on whole-of-building performance) including guidance for their design and construction.
      Timeline: 1/01/2016 - 31/12/2020
    • Deliverable 1.2: 100%
      • Development of a risk-targeted design methodology for new systems.
      Timeline: 1/01/2018 - 31/12/2020
 

2: Performance objectives and reparability of systems

Development of procedures to reliably assess and communicate the performance of new and conventional systems, including consideration of residual capacity of earthquake-damaged infrastructure and cost-effective repair techniques.

    • Deliverable 2.1: 100%
      • Develop methodology for assessing residual capacity of building structures (generalised and material specific).
      Timeline: 1/01/2016 - 31/12/2016
    • Deliverable 2.2: 100%
      • Use of large-scale test results for validation of models to assess performance (including residual capacity and repair techniques).
      Timeline: 1/01/2018 - 31/12/2020
    • Deliverable 2.3: 100%
      • Develop improved means of considering reparability within the performance assessment of new and conventional buildings systems.
      Timeline: 1/01/2018 - 31/12/2020
    • Deliverable 2.4: 100%
      • Develop alternative repair strategies for existing structures considering advanced performance measures.
      Timeline: 1/01/2018 - 31/12/2020
 

3: Implementation

Integration of reparability performance objectives into implementation standards and alignment with insurance policies optimised for rapid recovery.

    • Deliverable 3.1: 100%
      • Identify means (economic, regulatory, etc) to implementation of low-damage systems.
      Timeline: 1/01/2016 - 31/12/2020
    • Deliverable 3.2: 100%
      • Propose alternative methods to assess performance (economic or other relevant reparability performance objectives) of traditional building solutions with that of low-damage systems .
      Timeline: 1/01/2017 - 31/12/2020
