The utilisation workshop was built on preliminary discussions between the research team and agency end users, the Red Cross, community stakeholders and research partners regarding the development of better communication between remote Indigenous communities and fire and emergency services agencies, to reduce risk and build resilience by taking advantage of local knowledge and skills. The workshop addressed topics relating to volunteer models, and specifically the inapplicability, of the classical model, to people living in remote Indigenous communities.

Outputs of the workshop will shape the form of utilisation product/s that participants considered useful for addressing their specific and collective needs regarding volunteering.

This report is a summary of the workshop in Darwin, 11-12th November 2020, and provides summary documents addressing volunteer models adopting narrative formats (e.g. case studies, storytelling, etc); refers to videos addressing key issues for wider community distribution.

The CRC and CDU and our partners will work on the development and delivery of a second utilisation phase 2021. The in-kind support for this workshop, from supporting agencies and stakeholders, will ensure appropriate development of utilisation products during the second phase. This utilisation workshop was funded by the Bushfire and Natural Hazards CRC in direction linkage to the Building Remote Community Resilience to Natural Hazards Core Research project.

Limited-ductile reinforced concrete structures have been known to perform poorly when subjected to large seismic ground motions. Many buildings in Australia rely on reinforced concrete shear-cores as their primary lateral load resiting system, but these are only required to have a low standard of detailing as per the current concrete material standards AS 3600. While there is some literature available on the numerical and analytical modelling of rectangular shaped shear walls, non-rectangular shear walls have not been extensively analysed. {\textquotedblleft}C-shaped{\textquotedblright} shear walls are commonly found enclosing a service core, lifts, stairs and toilets. This paper presents a study which looks at the seismic performance of C-shaped shear walls with different steel reinforcement ratios for low, mid and high-rise buildings. The current earthquake actions code AS 1170.4 has been used for a preliminary design of the walls using a force-based design approach within which the intention is to satisfy the performance objective of life safety in a 500 year return period earthquake design level event in Melbourne. The displacement capacity of these different core walls has been calculated using a Displacement-Based Assessment procedure and complemented with finite element modelling program SeismoStruct. The results of a probabilistic seismic hazard analysis (PSHA) using the AUS5 recurrence model that has been conducted for the city of Melbourne has been used to calculate more accurate predictions of the displacement response spectra for 500 and 2500-year return periods. The C-shaped core walls have then been assessed by comparing the displacement capacity at different structural performance limit states to the displacement spectra derived from the current earthquake loading code AS 1170.4 and the spectra results from the PSHA for both the 500 and 2500-year return periods and for soil classes Be and De.
