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 ... -
A comparison of New Zealand seismic code requirements with other major design codes in the implementation of seismic resilient devices
(2021-04-14)In the ever-evolving earthquake engineering field, the need of the hour is to achieve earthquake-resistant buildings which have immediate occupancy following an earthquake. This implies that the demand for resilient dampers ... -
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) ... -
Are stronger, stiffer buildings indeed costlier?: Case study of RC frame buildings
(2021-04-14)Seismic codes/standards allow buildings to be designed for different lateral strength as long as the associated ductility and drift demands are catered for. The design seismic force is primarily controlled by a force ... -
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 ... -
Balancing seismic resilience and lean design to reduce the embodied carbon of buildings
(2021-04-14)The building and construction sector needs to make big changes to reduce greenhouse gas emissions if New Zealand is going to meet the legally binding targets of the 2019 Zero Carbon Act, and its commitments under the Paris ... -
Case studies on low damage mass timber structures with resilient connections
(2021-04-14)There is increasing public pressure to have seismic-resistant structures made with massive wooden panels such as Cross Laminated Timber (CLT). It is well-known that the type and behaviour of the connections govern the ... -
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, ... -
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 ... -
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 ... -
Enhancing seismic performance of existing buildings using viscous dampers for Forward-Directivity Earthquakes – The Challenges
(2021-04-14)Enhancing the performance of an existing building with viscous dampers for a Wellington site requires thorough consideration of near-fault effects, the Wellington Fault being so close. Earthquake records with forward-directivity ... -
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 ... -
How effective is a composting toilet system for protecting human health in an emergency context?
(2021-04-14)The Wellington Region is highly vulnerable to large earthquakes as it is crossed by active faults. Expected timeframes of 1 to 2 years for the re-establishment of networked wastewater management services provide urgency ... -
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, ... -
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 ... -
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 ... -
Low damage solution for a biomass boiler structure by a new three-dimensional seismic isolation
(2021-04-14)The February 2011 Christchurch earthquake caused significant property damage within Christchurch city. Since this devastating event, there has been a shift in engineering practice to Performance Based Design (PBD), to limit ... -
Panel Discussion - Towards a Resilient Future
(2021-04-14)Many lessons have been learnt from the major earthquakes in the past that have helped New Zealand become more resilient to earthquakes. But society’s circumstances, perspectives, and expectations are ever changing. How do ... -
Quantifying the Embodied Carbon Cost from Demolitions Following the Canterbury Earthquakes
