Is the bar too high? Foundation settlement in post-earthquake Christchurch
(2021-04-14)Three case studies are presented to show how significant ground deformation occurred with the Canterbury earthquake sequence, which in turn resulted in slopes to shallow foundations. The case studies are all from the ... -
Evaluation of a geospatial liquefaction model using land damage data from the 2016 Kaikoura earthquake
(2021-04-14)Earthquake induced liquefaction and lateral spreading can cause major damage to buildings and infrastructure networks. Common procedures to identify exposed areas such as cone penetration testing require extensive resources ... -
Earthquake Stories: Experiences of Building Performance in Earthquakes to enhance future building performance
(2021-04-14)The performance of the built environment during earthquakes plays an important role in reducing risk and enhancing the resilience of New Zealand’s urban centres. Although engineering codes and building standards regulate ... -
Wall-to-floor connection behavior in a low-damage concrete wall building
(2021-04-14)Following the 2010/2011 Canterbury earthquakes, approximately 60% of multi-story buildings with reinforced concrete walls required demolition. Both practitioners and researchers have increasingly realized that low-damage ... -
Numerical modelling of a concrete wall-steel frame building
(2021-04-14)Buildings that use concrete walls together with steel frames have become increasingly common in Christchurch, with around 35% of post-earthquake buildings using such mixed-material structural systems. This rapid shift in ... -
Identifying attributes influencing failure mechanisms in unreinforced masonry buildings using machine learning
(2021-04-14)Unreinforced masonry buildings comprise a major part of New Zealand's built heritage and were significantly damaged during the 2010-2011 Canterbury Earthquake sequence. There were 627 URM building assessed in the surveys ... -
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 ... -
Design of RSFJ Self-centring Brace for Ultimate Limit State
(2021-04-14)In previous studies, it was shown that the RSFJ brace assembly is prone to elastic buckling for which a new mechanism composed of two telescopic sections was introduced as a remedy to increase the elastic buckling load, ... -
Improvements to state school building design including the implementation of low-damage design criteria
(2021-04-14)The Ministry of Education (the Ministry) owns one of the largest property portfolios in New Zealand, with more than 15,000 buildings spread across nearly 2,100 state schools. Following the 2010 Canterbury earthquake sequence, ... -
Experimental seismic characterisation of gravel-granulated tyre mixtures and design implications
(2021-04-14)Worldwide, due to the large amount of end-of-life tyre (ELT) stockpiles, reusing and recycling of ELTs in civil engineering applications have become a priority, significantly contributing to lessen environmental and health ... -
Directing Low-Damage Seismic Design with Building Functionality
(2021-04-14)The upcoming New Zealand Low-Damage Seismic Design (LDSD) guidance information, currently in preparation, is widely anticipated to provide a reference point for aligning low-damage seismic performance targets. A key aspect ... -
Quantifying the Embodied Carbon Cost from Demolitions Following the Canterbury Earthquakes
(2021-04-14)The 2010/2011 Canterbury Earthquake Sequence resulted in severe financial loss, loss of life and disruption in Christchurch due to liquefaction and damage from strong shaking, which led to the widespread displacement of ... -
Incorporating the influence of duration on dynamic deformation capacity in seismic assessment
(2021-04-14)The dynamic deformation capacity of a structure is the peak storey drift ratio it can safely withstand without collapsing due to dynamic instability. In a previous study, the authors developed a robust procedure to compute ... -
Advances in Floor Diaphragm In-Plane Modelling Using Truss Elements
(2021-04-14)Different methods to model building floor diaphragm in-plane stiffness with truss elements are compared to identify the method most suitable for analysis in design. The methods considered include (i) Elastic truss, (ii) ... -
1170.5 Reimagined: from a structural designers view
(2021-04-14)Our loadings code has adapted and extended to incorporate new knowledge as it has emerged over the last 50+ years: could a re-write encourage engineers to design better buildings? This paper outlines some intentionally ... -
Depth and Shape of the Basement Surface Beneath Wellington City, Based on Gravity and Seismic Constraints
(2022-04-27)A new basin-depth map for the Wellington Central Business District shows a maximum depth of 540 m near the Wellington Stadium. This is twice that previously proposed. Our new basin geometry constraints are from a residual ... -
Elastic Design (μ=1.0) of Damage Avoidance Structures
(2022-04-27)Damage Avoidance Design (DAD) has been considered an efficient way for seismic design. Different solutions to achieve a robust DAD structure has been proposed and tested by researchers in the past. However, there is a lack ... -
