NZ Low Damage Seismic Design Guidance Information
(2021-04-14)In a resilient built environment, buildings should be able to be occupied and used after significant earthquakes. New Zealand’s Building Code, like many others, is primarily focused on the preservation of life, with damage ... -
The Optimised Sliding Hinge Joint (OSHJ): Design, Detail, and Implementation in Practice
(2021-04-14)The Optimised Sliding Hinge Joint (OSHJ) is a low-damage, resilient, versatile, and cost effective seismic resisting system developed primarily for Moment Resisting Steel Framed (MRSF) buildings. The OSHJ is the optimized ... -
Design of the Ashburton District Council Civic Centre: A steel designers' learnings from an engineered timber building design
(2021-04-14)This paper discusses the learnings from the structural engineering for the Ashburton District Council (ADC) Civic Centre. The building was initially steel but after consulting with the Ashburton community an alternative ... -
Simplified numerical modeling of reinforced concrete columns with smooth rebars
(2021-04-14)Pre-1970s concrete buildings in New Zealand were commonly constructed with smooth longitudinal reinforcing bars. The NZSEE guideline for the seismic assessment of existing buildings (NZSEE C5) recognizes that the seismic ... -
QuakeKit: Communicating Engineering Risks to Youth in the South Island of New Zealand
(2021-04-14)QuakeKit is a collaborative project through QuakeCoRE, AF8 [Alpine Fault magnitude 8], Canterbury Seismic Instruments (CSI), and University of Canterbury, funded by the Unlocking Curious Minds fund. QuakeKit has two parts: ... -
Performance comparison of standard and seismic glazing systems
(2021-04-14)Glazing systems are non-structural elements in a building that, more often than not, are given little consideration in seismic design. Recent experimental work into glazing systems at the University of Canterbury has shown ... -
From mud to modules and beyond - the post-2011 Christchurch evolution of earthquake geotechnical engineering in New Zealand
(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 ... -
Designing for Uncertainty
(2021-04-14)Structural engineers are familiar with seismic design using a compliance pathway. This typically requires ensuring the provided capacity of structures, expressed as a single value, exceeds the seismic demand, also expressed ... -
Evaluation of assessment approaches for soil-foundation-structure interaction of frame buildings
(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 ... -
Dras Fault: a major active fault in Kashmir Himalaya
(2021-04-14)Previous works have shown that the oblique tectonic convergence between the lithospheric plates of India and Eurasia in NW Himalaya is primarily manifested by the formation of a series of fold- and thrustbelts, and the ... -
Ground motion simulation validation with explicit uncertainty incorporation for small magnitude earthquakes in New Zealand
(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
(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
(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
(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
(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
(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
(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
(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
