Self-centring bracing system: avoidance of elastic buckling for braces with one intermediate damper
(2020-04-22)Today, more attention is being given to timber material by practitioners as a structural member owing to benefits that this material can offer such as high strength to weight ratio, being environmentally friendly and ... -
Wellington's sedimentary basin and its role in amplifying earthquake ground motions: new CBD 3D model and maps
(2020-04-22)During the Mw7.8 Kaikōura earthquake, ground motions in central Wellington were clearly influenced by both the nature of the earthquake source and local amplification effects due to the sedimentary basin. These effects ... -
Numerical modelling of reinforced concrete walls with minimum vertical reinforcement contents
(2020-04-22)Reinforced concrete (RC) structural walls are effective lateral force-resisting components that are commonly implemented in tall buildings. Recent studies have investigated the impact of minimum vertical reinforcement ... -
Influence of failure mode uncertainty on the collapse capacity of RC components
(2020-04-22)Acceptance criteria for reinforced concrete components are selected based on the assumption that the failure mode of a component is deterministic. This paper makes a case suggesting that such an assumption may be untrue ... -
Design scenarios for piles in ground subject to liquefaction
(2020-04-22)Seismic shaking and liquefaction with its associated loss of soil strength and ground movements/deformations can be damaging to buildings and their foundations. Understanding ground behaviours and soil-structure interaction ... -
Soil-structure interactions of piled buildings on ground subject to liquefaction and lateral displacements
(2020-04-22)The lateral design of piled foundations for buildings in liquefiable ground is challenging because of potential reduced lateral support and possible lateral ground displacements. Soil-structure interaction (SSI) analysis ... -
How would changes to serviceability limit state design criteria impact likely repair costs?
(2020-04-22)The earthquake engineering community is currently grappling with the need to improve the post-earthquake reparability of buildings. As part of this, proposals exist to change design criteria for the serviceability limit ... -
Robustness and accuracy of model-free structural health monitoring
(2020-04-22)Rapid, accurate structural health monitoring (SHM) assesses damage to optimise decision-making. Many SHM methods are designed to track nonlinear stiffness changes as damage. However, highly nonlinear pinched hysteretic ... -
Impacts of innovation in performance-based building code
(2020-04-22)The purpose of this study is to assess the benefits and the unintended consequences of innovation in performance-based building code with an emphasis in New Zealand building code. Also, this paper examines how innovative ... -
Simplified design procedures for shear piles subject to liquefaction induced lateral spread with evacuation
(2020-04-22)The lateral load transfer between a pile and laterally spreading ground during an earthquake is a complex soil-structure interaction problem given the significant nonlinearity of the stress-strain behaviour of soils during ... -
Mitigation of liquefaction induced lateral spread using jet grout shear walls
(2020-04-22)The load transfer mechanism between ground subject to liquefaction induced lateral spreading and jet grout shear walls is complex. The shear walls comprise rows of jet grout columns, constructed in a primary-secondary ... -
Correlation between standard penetration test and shear-wave velocity in Wellington, New Zealand
(2020-04-22)The New Zealand standard NZS1170.5:2004 (amendment 1; Sep 2016; Earthquake actions) recommends seven methods for the determination of site classification as defined in Section 3.1.3.1. The most preferable method is direct ... -
A study of current research achievements and challenges on the application of High Strength Steel (HSS) endplates in seismic resisting systems
(2020-04-22)High strength steel is increasing in demand due to economic and mechanical benefits. A typical mechanical characteristic of HSS is that the ductility of the material decreases along with the increase in strength. This has ... -
Seismic base isolation of high-rise RC shear wall building using lead core rubber bearings
(2020-04-22)The use of base isolation technique is an effective way to control the seismic demands in buildings. The RC shear wall buildings represent the typical high-rise construction in several parts of the world. The seismic story ... -
Seismic response of half-scale seven-storey RC systems with torsional irregularities: blind prediction
(2020-04-22)Past earthquakes have highlighted vulnerabilities to damage or collapse of building structures due to torsional response. While methodologies to capture torsional demand due to strength and stiffness irregularities have ... -
Review of recently constructed buildings that combine steel frames and concrete walls
(2020-04-22)Recent building construction in New Zealand has exhibited an increase in the use of structural steel due to its availability and perception of good seismic performance. Despite the renewed popularity of structural steel ... -
Towards a better understanding of the development of the strength in Asymmetrical Friction Connections (AFCs)
(2020-04-22)In the current design practice, the strength of Asymmetric Friction Connections (AFCs) is calculated considering the friction force developed at both sliding interfaces using the bolt tension reduced by the moment – shear ... -
Slip rate variations on major strike-slip faults in central New Zealand and potential impacts on hazard estimation
(2020-04-22)Geological investigations over the last two decades have demonstrated that major strike-slip faults in central New Zealand (e.g., Awatere, Clarence, Wellington faults) have experienced significant millennial-scale variations ...
