Earthquake prone public buildings: balancing life safety risks and community costs
(New Zealand Society for Earthquake Engineering, 2021-04-14)
The focus on seismic risk following the 2011 Christchurch and 2016 Kaikoura earthquakes has seen the closure of several public buildings across the country. The introduction of the Building (Earthquake-prone Buildings) ...
Investigating the impact of design criteria on the expected seismic losses of an office building
(New Zealand Society for Earthquake Engineering, 2021-04-14)
Low Damage Seismic Design (LDSD) guidance material being developed by Engineering NZ is considering a design drift limit for multi-storey buildings of 0.5% at a new damage control limit state (DCLS). The impact of this new ...
Seaview Wharf: risk-based thinking underpins the future
(New Zealand Society for Earthquake Engineering, 2021-04-14)
Wellington’s Seaview Wharf is a critical asset in the Lower North Island fuel supply system, including after significant seismic events. Recent annual fuel supply for the region has exceeded 1 Million tonnes, and there is ...
Full Waveform Tomography for the upper South Island region, New Zealand
(New Zealand Society for Earthquake Engineering, 2021-04-14)
In this paper, we apply Full Waveform Tomography (FWT) based on the Adjoint-Wavefield (AW) method to iteratively invert an existing 3-D geophysical velocity model for the upper South Island region, New Zealand. Through the ...
Experimental loading protocols to evaluate the seismic performance of floor systems
(New Zealand Society for Earthquake Engineering, 2021-04-14)
Major earthquakes, such as the Canterbury and Kaikoura events recorded in New Zealand in 2010 and 2016 respectively, highlighted that floor systems can be heavily damaged. At a reduced or full scale, quasi-static experimental ...
Wellington Building Inventory: Rapid Earthquake Response Framework
(New Zealand Society for Earthquake Engineering, 2021-04-14)
This paper is focused on the design and implementation of a functional tool to evaluate and communicate the seismic risk to increase resilience and reduce human and economic loss. Wellington has been selected as the case ...
Case studies on low damage mass timber structures with resilient connections
(New Zealand Society for Earthquake Engineering, 2021-04-14)
There is increasing public pressure to have seismic-resistant structures made with massive wooden panels such as Cross Laminated Timber (CLT). It is well-known that the type and behaviour of the connections govern the ...
Philosophical reflexions following the Lyttleton 2011 New Zealand Earthquake: Ten years after
(New Zealand Society for Earthquake Engineering, 2021-04-14)
At 12:51 p. m. on 22 February 2011, the Mw 6.3 Lyttelton earthquake struck the Canterbury region of New Zealand. The seismic event was reported as the result of the rupture of a previously unknown geological fault, 5.9 km ...
A comparison of New Zealand seismic code requirements with other major design codes in the implementation of seismic resilient devices
(New Zealand Society for Earthquake Engineering, 2021-04-14)
In the ever-evolving earthquake engineering field, the need of the hour is to achieve earthquake-resistant buildings which have immediate occupancy following an earthquake. This implies that the demand for resilient dampers ...
Risk-Targeted Hazard Spectra for Seismic Design in New Zealand
(New Zealand Society for Earthquake Engineering, 2021-04-14)
The promotion of risk-targeted hazard spectra as the basis of seismic design internationally has increased over the past decade. Risk-targeted hazard spectra are derived through convolution of hazard curves with representative ...
