    • Dealing with uncertainty in prediction of lateral spread 

      Smith, Vincent; Palmer, Stuart; Elwood, Kenneth (2022-04-27)
      Prediction of lateral spread for seismic assessment and design includes considerable uncertainty. Two widely used prediction methods are Youd et al. (2002) and Zhang et al. (2004). Five case studies across the Wellington ...

    • Depth and Shape of the Basement Surface Beneath Wellington City, Based on Gravity and Seismic Constraints 

      Stronach, Alistair; Stern, Tim (2022-04-27)
      A new basin-depth map for the Wellington Central Business District shows a maximum depth of 540 m near the Wellington Stadium. This is twice that previously proposed. Our new basin geometry constraints are from a residual ...

    • Interim Results from empirical ground motion model evaluation for the NZ National Seismic Hazard Model Update 

      Lee, Robin; Bradley, Brendon; Manea, Elena; Hutchinson, Jesse (2022-04-27)
      As a part of the ongoing 2022 NZ National Seismic Hazard Model (NSHM) Update, the predictive capabilities of candidate empirical ground motion models are evaluated to ascertain models which provide good prediction for NZ ...

    • Liquefaction potential of sand-gravel mixtures: experimental observations 

      Pokhrel, Abilash; Chiaro, Gabriele; Cubrinovski, Misko; Kiyota, Takashi (2022-04-27)
      Case histories from at least 27 earthquakes worldwide (including three from New Zealand: 1929 Mw7.6 Murchison earthquake; 2010 Mw 7.1 Darfield earthquake; and 2016 Mw 7.8 Kaikoura earthquake) have indicated that liquefaction ...

    • Modelling the out-of-plane buckling behaviour of BRBFs 

      Sistla, Saiteja; Chandramohan, Reagan; Sullivan, Timothy J. (2022-04-27)
      The objective of this study is to assess the impact of modelling the out-of-plane buckling behaviour of buckling-restrained braced frames (BRBFs) on their estimated seismic performance. A number of recent studies have ...

    • Post-earthquake functional recovery: A critical review 

      Zhan, Shen; Chang-Richards, Alice; Elwood, Kenneth; Boston, Megan (2022-04-27)
      Functional recovery not only transforms the retrofit of damaged buildings from an earthquake event but also contributes to community resilience. This paper aims to provide a state-of-the-art literature review of functional ...

    • Seismic strengthening of the Seatoun Tunnel 

      Wymer, Paul; Latham, Dean; Radosavljevic, Bojan; Brabhaharan, Pathmanathan; Tawfeek, Faiz (2022-04-27)
      The Seatoun tunnel is a 147m long, vehicle and pedestrian tunnel built in 1906-1907 to provide a tram connection between the suburb of Seatoun the city of Wellington.  In 2011, the Seatoun tunnel structure was assessed as ...

    • Social Influences on behavioural response to earthquake shaking 

      Vinnell, Lauren; Inch, Piata; Johnston, David; Horspool, Nick (2022-04-27)
      Many earthquake injuries in Aotearoa New Zealand occur because people either do not act quickly to protect themselves or act in a way which can lead to harm. Earthquakes are an uncertain context in which to make behavioural ...
