From mud to modules and beyond - the post-2011 Christchurch evolution of earthquake geotechnical engineering in New Zealand
(New Zealand Society for Earthquake Engineering, 2021-04-14)
The extent of land damage during the Canterbury earthquakes was a wake up call. It disproportionately impacted many aspects of the recovery, including costs, time, community cohesion and individual welfare. The earthquake ...
Evaluation of assessment approaches for soil-foundation-structure interaction of frame buildings
(New Zealand Society for Earthquake Engineering, 2021-04-14)
The consideration of soil and foundation deformations within the seismic assessment of buildings can be critical for evaluating the likely load paths and consequent deformations. Frame buildings provide numerous complexities ...
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 ...
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 ...
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 ...
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 ...
Drift Demand Estimates for Inelastic Torsional Response of Half-scale Seven-storey RC Specimens
(New Zealand Society for Earthquake Engineering, 2021-04-14)
Existing reinforced concrete buildings with irregularities are susceptible to torsional response and resulting localised damage or collapse under seismic excitation. Primary source of torsional response can be inherent ...
Influence of damping models on nonlinear seismic response of a base isolated building
(New Zealand Society for Earthquake Engineering, 2021-04-14)
This paper discusses the effect of different damping models on nonlinear seismic response of a 8 storey 2D base isolated (BI) building: (1) Rayleigh damping proportional to the mass and initial stiffness matrices, (2) ...
