2018 RfP Information

Next Flagship RfP Collaboration Meeting: TBD

Draft Flagship Programme 2018:

Flagship 3 Coordinated Project will provide fundamental research on risks, impacts, and solutions for multi-storey existing buildings in Wellington, with a particular focus on commercial buildings generally of concrete construction. Wellington commercial market will likely be heavily impacted by new seismic assessment guidelines due to typical clauses in rental contracts that buildings must be above 67% NBS.  Many new assessments are likely to fall below 67%.  Furthermore, densification of the CBD with 50,000 new residents in the next 20 years, will result in conversion of many commercial buildings to housing with a change in the risk profile for the city.

Past focus, in terms of both research and policy on existing buildings, has generally been on lowrise URM although large nonductile concrete buildings likely represent the greatest life safety and economic risk in NZ. Furthermore, assessment and retrofit approaches for concrete buildings more complex and expensive than URM, thus requiring additional research focus.

Understanding the risks and impacts of multi-story building failures and achieving viable solutions requires a multi-disciplinary approach. The Wellington focus provides contextual connection between the disciplines and provides connection with several additional complementary efforts:

• Flagship 5 with a focus on Wellington Resilience Strategy
• Smart Seismic Cities being developed in collaboration with WCC and EQC
• Future Wellington Earthquake Case Study through QuakeCoRE for scenario studies

2018 efforts under the Flagship 3 Coordinated Project have been identified as follows (most efforts expected to continue beyond 2018:

• CBD-wide studies:

–      Inventory (occupancy, ownership, condition, proportion of CBD), regional modelling to consider impacts of failures of existing concrete buildings (Nick/Ken)Student funding

–      Cordoning – baseline study (Caroline/Laurie Johnston/Jason(Shannon))

• • • Student funding
• Structural Engineering:

–      Deformation capacity of nonductile columns with high axial loads (Ken)

• • • Scholarship student, funding for testing

–      Assessments and retrofits for precast floors and diaphragm load path (Angela/Des/ Ken/Rick)

• • • BRANZ funding?

–      Modelling of whole-of-building performance – relation between %NBS and collapse probability (Reagan)

• • • Student funding
• Social/Economic/Legal:

–      Prioritisation/trade-offs in retrofit/replacement/status-quo/change-of-use/etc of concrete buildings (including role of insurance) (Ilan/Olga)

• • • Student funding

–      Legal perspectives on risk for tenants and owners of commercial buildings (John Hopkins/Julia)

• • • Project/Student funding
• Joint with Flagship 5

–      Social perspectives on risk for tenants and owners of commercial buildings (Julia/ John McLure/David Johnston)

• • • Funding from Flagship 5

–      Iwi ownership of building assets in Wellington and Mautaranga perspectives (coordinated with FP5 Wellington iwi project – F3 rep?)

• • • Engagement funding 

RfP Projects are being sought in the following areas:

Opportunity 

The vast majority of earthquake-related deaths occur due to building collapse, and therefore the most direct way to minimise fatalities and injuries is to first identify then remediate or demolish the nation’s earthquake-prone building stock. In March 2014, the Earthquake-prone Buildings Bill passed its first reading in Parliament, with the express purpose to establish a nationally consistent approach to addressing the risk posed by earthquake-prone buildings (EPB). Considering the number of EPB throughout NZ, the high costs of remediation, and the heritage value of many EPB, this legislation has broad implications for the NZ economy, owners of earthquake-prone buildings, and all members of the community.

There is a window of opportunity for QuakeCoRE researchers to significantly inform this national debate with leading-edge multi-disciplinary research that seeks a balance between heritage, safety, and economics. This Flagship will pursue three interconnected families of research needs all linked by case studies. Conventional economic decision-support tools will be advanced in order to address the current failure to recognise the complexities of low-frequency high-consequence events with community-wide impacts and the value of cultural heritage. Drawing upon multidisciplinary community datasets, the scope of the EPB ‘problem’ in NZ will be quantified rigorously for the first time. This ‘baseline’ will then be used in the development of robust multi-scale models for prototypical building systems, providing an improved understanding of their seismic response characteristics and reduce current excessively conservative structural assessments which may lead to unnecessary demolition or overly-conservative remediation strategies. Finally, QuakeCoRE will build on its proven track record related to the assessment and mitigation of URM buildings to develop cost-effective and aesthetically-acceptable methods for seismic strengthening of pre-1970’s concrete structures and other non-ductile buildings. These efforts will be linked using community case studies for Auckland and Wanganui.
