Ground motion simulation validation with explicit uncertainty incorporation for small magnitude earthquakes in New Zealand
(New Zealand Society for Earthquake Engineering, 2021-04-14)
This study investigates the uncertainty of simulated earthquake ground motions for small-magnitude events (Mw 3.5 – 5) in Canterbury, New Zealand. 148 events were simulated with specified uncertainties in: event magnitude, ...
Three-storey Configurable Steel Framed Building Incorporating Friction Based Energy Dissipaters: Structural Configuration and Instrumentation
(New Zealand Society for Earthquake Engineering, 2021-04-14)
A 9 m high, full-scale three-storey configurable steel frame composite floor building incorporating friction based connections is being tested using two linked bi-directional shake tables at the International joint research ...
Enhancing seismic performance of structure with different configuration of passive D3 viscous damper
(New Zealand Society for Earthquake Engineering, 2021-04-14)
For each structure and project, there is a unique desire. Seismic building performance can be increased using dissipation systems like viscous dampers. However, these improvements are offset by the added cost if the total ...
Developments in the use of high resolution point cloud data to inform heritage restoration
(New Zealand Society for Earthquake Engineering, 2021-04-14)
While considered an emerging technology at the time of the Canterbury Earthquakes, extensive use of laser scanning derived point cloud data over the last 10 years has resulted in refined processes with new and existing ...
Performance Comparison of Buckling-Restrained Braces and Friction Dampers Adopted for Retrofit of an Existing RC Frame Building Using Performance-Based Retrofit Procedure
(New Zealand Society for Earthquake Engineering, 2021-04-14)
This paper presents a performance-based retrofit approach for designing and performance comparison of Buckling -Restrained Braces (BRBs) and Friction Dampers as retrofit strategies for RC frame buildings. An overview of ...
Monotonic and Cyclic Pushover Testing of Isolated Piles of the Whirokino Trestle
(New Zealand Society for Earthquake Engineering, 2021-04-14)
In New Zealand, over 60% of State Highway bridges were designed and built during eras with low seismic provisions and most of these bridges are supported by pile foundations. An improved understanding of the in-service ...
Liquefaction Assessment of Reclaimed Land at CentrePort
(New Zealand Society for Earthquake Engineering, 2021-04-14)
The 2016 Mw7.8 Kaikōura earthquake caused widespread liquefaction in the port of Wellington (CentrePort), New Zealand which produced substantial lateral ground movements along with global and differential settlement. ...
Blenheim gravel liquefaction assessment using the Chinese dynamic cone penetration test
(New Zealand Society for Earthquake Engineering, 2021-04-14)
Worldwide, one of the issues that has been constantly brought to attention by engineers is the lack of guidance for geotechnical characterization and liquefaction assessment of gravelly soils.
In gravelly soils, the ...
The 2022 New Zealand National Seismic Hazard Model Revision
(New Zealand Society for Earthquake Engineering, 2021-04-14)
We are embarking on the most significant revision of the NSHM in more than 20 years. An international team of more than 50 scientists is contributing to two working groups: 1) Seismicity Rate Models (SRM); and 2) Ground ...
How practitioners can work together to achieve better seismic performance outcomes for buildings and infrastructure
(New Zealand Society for Earthquake Engineering, 2021-04-14)
A key recommendation from the Canterbury Earthquakes Royal Commission was that there should be “greater cooperation and dialogue between geotechnical and structural engineers” to help improve the seismic performance of ...
