Earthquake Strengthening of Heritage Buildings: Challenges & Opportunities in Small Towns
Workshop Leaders: Olga Filippova / Jason Ingham
Central streets of many of Aotearoa’s small towns are lined with late 1800s/early 1900s commercial buildings. While these buildings shape our understanding of the past, their future is uncertain due to high costs of retrofitting and low economic viability. This workshop will showcase successful seismic strengthening projects of heritage buildings in Napier. Key experts, including structural engineer, heritage consultant and architect, will discuss proposed solutions as well as challenges involved in delivering these projects. Understanding of what drives property investors to restore heritage buildings will also be explored. The second half of the workshop will be off-site and participants will have an opportunity to tour some of the exemplary retrofit projects completed in the centre of Napier.
Monday 28th August 2.00pm – 4.00pm
Modelling and analysis of ground-motion spatial correlations for several engineering use cases
Workshop Leaders: Jack Baker / Brendon Bradley
This small workshop will examine the multiple engineering models for which spatial correlations are important to consider. The different methods for quantifying spatial correlations will be examined, and variation in results that can occur discussed. This workshop is intended to provide granular discussions of this topic and is intended specifically for people working on ground-motion modelling problems, and not for a broader audience.
Tuesday 29th August – 9.00am -12.00 pm & 1.00pm – 4.00pm
Seismic Protection Systems and Retrofit Techniques for Steel & Reinforced Concrete Buildings
Workshop Leaders: Geoff Rodgers / Santiago Pujol
The event will showcase presentations on the latest seismic protection devices, systems, and methods, as well as recent strengthening and retrofit techniques. Consideration will be given to methods to reduce earthquake damage both to structural and non-structural elements including ideas in use outside New Zealand. The workshop will be run in two parts, where conventional retrofit methods, such as FRP-wrapping of columns and the retrofit of braces (concentric or eccentric bracing) is considered, and then compared to alternate methods such as the use of base-isolation, retrofit with BRBs, or other devices such as friction connections, force-limiting fuses, viscous fluid dampers, or other emerging technologies. The workshop will end with a panel discussion on the relative strengths and weaknesses of the two different retrofit design options.
Tuesday 29th August – 9.00am -12.00 pm & 1.00pm – 4.00pm
Developing tsunami-resilient communities
Workshop Leader: David Johnston
Tsunami remains an ever-present threat to lives and property along the coasts of most of the world’s ocean. Major subduction zone earthquakes and tsunami, such as in the Indian Ocean (2004) and Japan (2011), have focused attention on the potential impact of a tsunami of similar size and extent occurring locally to Aotearoa New Zealand. The Aotearoa New Zealand scientific and emergency management communities have directed attention towards the risk of a tsunami generated from an earthquake at the Hikurangi subduction margin, off the east coast of the North Island. The emergency management sector is reviewing their existing arrangements based on observations from Japan (and elsewhere) and our knowledge of risk reduction options. However, much remains to be done to reduce the risk from a future tsunami in Aotearoa New Zealand. This workshop will be divided into two parts which can be attended together or separately.
Tsunami Part 1: Exploring the Elements of an Effective Integrated Tsunami Risk Management System
This part of the workshop will explore the development of an integrated tsunami risk management systems in Aotearoa New Zealand, drawing on successes of similar systems overseas. By integrating hazard assessment, warning guidance, and mitigation activities communities and local/national government entities have created a range of tools to develop communities’ resilience to local and distant-source tsunami. Elements include tsunami forecasting, educational experiments, early alerting systems, evacuation drills, and design guidance for tsunami-resilient communities.
Tsunami Part 2: Engineering Design for Tsunami
This part of the workshop will explore aspects of engineering design for tsunami. Central to tsunami risk mitigation is the protection of critical infrastructure within inundation zones as well as evacuation-designated buildings which must be designed to withstand and remain fully or partially operational after a tsunami. Guidance documents for tsunami design of buildings exist in the USA and Japan. This second part of the workshop will explore the key engineering principles of tsunami design of buildings and discuss current guidance, research, and knowledge gaps.
Tuesday 29th August – 1.00pm – 4.00pm
Earthquake and disaster resilience through Pacific-Indigenous design and diasporic community innovation
Workshop Leader: Siautu Alefaio
This workshop is an opportunity to engage with Pacific educators, leaders and experts from different Pacific diasporic communities. We draw on Talanoa (cultural-led dialogue) to discuss experiences and work within the diaspora that showcase community innovation and Pacific-Indigenous resilience. The workshop will be facilitated by NIUPATCH and include our communities of practice: Roscommon school community resilience podcast, Newtown Wellington PIC: strengthening Pacific church buildings toolkit, and Pacific local community response – Cyclone Gabrielle. We feature special guests from University of Auckland who are renown scholar-practitioners: architect Peseta Lama Tone and civil engineer Tumanako Fa’aui. Together our Pacific village-collective will share as community hubs and sources of resilience on Pacific communities particularly before, during and after disasters.
Through talanoa, this workshop will explore how Pacific-Indigenous design and diasporic community innovation contribute to community resilience. We aim to highlight the significance of community-led solutions for disasters, particularly in Pacific communities that are frequently and disproportionately affected by these events.
