Push-over analysis of a 3D architectural wharf structure including soil-structure interaction
(2021-04-14)A new wharf structure was proposed for Te Wānanga in central Auckland. Due to the complex geometry of the proposed wharf, which included plan irregularity, open apertures, deck-suspended planter boxes, suspended nets and ... -
Development of Dissipative Controlled Rocking Bridge Columns on Monopile Foundations
(2021-04-14)In this research, a low-damage seismic design detail is developed for bridge columns supported on monopile foundations. The low-damage system aims to minimise, and potentially eliminate, the repair time and costs to a ... -
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 ... -
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 ... -
Application of the Geotechnical Step-Change Provisions of the 2017 MBIE Guidelines for the Seismic Assessment of Buildings
(2021-04-14)The Seismic Assessment of Existing Buildings, Technical Guidelines for Engineering Assessments (“the Guidelines”) provides engineers with a consistent means to assess the seismic behaviour of existing buildings with respect ... -
The State of Practice in SSI Modelling in New Zealand: Insights from an Engineering Profession Survey
(2021-04-14)There is a relatively brief consideration for soil-structure interaction (SSI) effect in the New Zealand guidelines for the seismic assessment of structures. Recent earthquake events including the Kaikōura earthquake of ... -
Managing Seismic Risk across Process and Manufacturing Facilities
(2021-04-14)To manage seismic risk at large Process and Manufacturing Facilities requires a PCBU to understand the compliance requirements from legislation. However this is not an easy task as there are multiple Acts, Regulations, ... -
Identifying vulnerable reinforced concrete buildings in Wellington using a simple assessment methodology
(2021-04-14)The application of a simple yet effective method to assess reinforced concrete buildings in New Zealand is discussed. It is proposed that this method be used to identify and prioritise the most vulnerable reinforced concrete ... -
Development of the New Zealand Community Fault Model – version 1.0
(2021-04-14)There has been a long-identified need in New Zealand for a community-developed three-dimensional fault model that is accessible and available to all. Over the past year, work has progressed on building and parameterising ... -
Investigation of the Plastic Drift Capacity of RC Frames with Beam-Column Joint Failure
(2021-04-14)MBIE/NZSEE guidelines have various methods to assess existing buildings, of which Displacement Based Assessment (DBA) is one. This paper reports on the application of DBA to reinforced concrete (RC) frames where beam-column ... -
Source modelling insights from ground motion simulation validation of moderate magnitude active shallow crustal earthquakes in New Zealand
(2021-04-14)Hybrid broadband ground motion simulation validation has been an ongoing effort in NZ with recent studies focussed on active shallow crustal earthquakes of large magnitude (Mw>7.0) and small magnitude (3.5<Mw≤5.0). Lessons ... -
Earthquake prone public buildings: balancing life safety risks and community costs
(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) ... -
An automation approach to the seismic assessment and strengthening of unreinforced masonry buildings
(2021-04-14)Large scale seismic assessments in areas of dense unreinforced masonry buildings (URM) is a significant challenge for structural engineers. URM buildings respond to earthquake excitation with a variety of mechanisms as ... -
Validation of NZ small-magnitude ground-motion simulations using complex structural systems
(2021-04-14)This study assesses the need to consider complex structural models in ground-motion simulation validation. It develops a novel statistical framework to quantify the proportion of the differences in structural responses ... -
The national seismic hazard model for New Zealand: Contributions from the deep south
(2021-04-14)The New Zealand National Seismic Hazard Model (NSHM) is being updated for the first time since 2010 in a multi-institutional project led by GNS Science (www.gns.cri.nz/NSHM). In the interim, several major well-instrumented ... -
Development and implications of an expanded national earthquake catalogue for New Zealand
(2021-04-14)In the last two decades, New Zealand (NZ) has experienced significant earthquakes, including the 2010 M 7.2 Darfield, 2011 M 6.2 Christchurch, and 2016 M 7.8 Kaikōura events. Amongst these large events, tens of thousands ... -
Residential Building Repair Cost and Claim Settlement Time from the Canterbury Earthquake Sequence
(2021-04-14)This study analyses the Earthquake Commission’s (EQC) insurance claims database to investigate the influence of seismic intensity and property damage resulting from the Canterbury Earthquake Sequence (CES) on the repair ... -
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, ... -
ATC-145: Influence of prior shaking on earthquake response and repair requirements for structures and elements
(2021-04-14)ATC-145 is a FEMA funded project aimed at developing a Guide for repair of earthquake damaged buildings to achieve future resilience. Thanks in part to EQC funding, the project includes substantial New Zealand representation. To ... -
How effective is a composting toilet system for protecting human health in an emergency context?
