Design of Mixed Angle Screw CLT Hold-Down Connections to New Zealand Timber Standards
(2023-04-19)Mixed angle screws provide a strong, stiff, and ductile hold-down solution for high-capacity Cross Laminated Timber (CLT) shear walls. Timber is an inherently brittle material and most inelastic responses in timber structures ... -
Advanced seismic design of concrete-to-concrete structural connections
(2023-04-19)Seismic strengthening of concrete buildings and bridges may require the addition of new concrete members or overlays. One way of connecting new concrete to existing concrete is using post-installed rebar (PIR) connections. ... -
Finite Element Convergence Study of the Asymmetric Friction Connection (AFC) in the Optimised Sliding Hinge Joint (OSHJ)
(2023-04-19)The Optimised Sliding Hinge Joint (OSHJ) is a cost-effective, low damage seismic resisting beam-column connection developed for Moment Resisting Steel Framed (MRSF) buildings. The OSHJ is the optimised version of the ... -
A quantitative risk assessment of seismic slope stability for a tailings dam
(2023-04-19)Tailings are a by-product of mining, consisting of silts and sands from the processed rock or soils and susceptible to liquefaction under earthquakes. Tailings Storage Facilities (TSFs) include dams that are designed and ... -
Influence of remedial ground densification on seismic site amplification
(2023-04-19)While the capability of remedial ground densification techniques to mitigate the adverse effects of liquefaction has been widely investigated in recent decades, the characterization of ground motion amplification in the ... -
Seismic design of an XblocPlus® revetment using multi-model approach
(2023-04-19)When designing and constructing revetments, there is often a drive to reduce the footprint due to space constraints and a limited supply of suitable rock armour materials. Concrete armour units present a potentially more ... -
Displaced But Not Moved: Performance-Based Foundation Design
(2023-04-19)Improved understanding of seismicity within New Zealand and globally has led to an increase in seismic hazard for many locations. High seismic acceleration demands (e.g. >1g) for buildings and infrastructure have led to ... -
Innovative Resin Injection Ground Improvement to Build Up Seismic Resilience of Existing Water Structures
(2023-04-19)The existing Wellington Water’s Waterloo Water Treatment Plant (WTP) in Wellington, New Zealand is an important post-earthquake facility for the Wellington region. The WTP is founded on soils prone to liquefaction and ... -
Seismic application of fillet and partial penetration butt welds
(2023-04-19)Fillet and partial (incomplete) penetration butt welds are the most cost-effective weld details for structural steel connections. Correctly sized and executed, double-sided, balanced fillet welds and partial penetration ... -
Development, verification, and validation of a buckling-fatigue steel material model
(2023-04-19)Currently, there are limited constitutive models available in finite element analysis packages that reliably capture the coupled effects of bar buckling and fatigue. However, such a model is needed for reliable estimation ... -
Predictive models for changes in reinforcement characteristics due to strain ageing effects
(2023-04-19)One of the factors affecting repair feasibility of buildings damaged by earthquakes is the potential effects of strain ageing of reinforcement. Since strain ageing can lead to an increase in structural member strength and ... -
A prescriptive method for the design of new steel moment frame structures with supplemental damping
(2023-04-19)This paper presents a prescriptive method for the design of new steel moment frame structures with supplemental damping using fluid viscous dampers. The prescriptive method uses Modal Response Spectrum Analysis (MRSA) ... -
“Modal crimes” in structural engineering
(2023-04-19)With increasing seismic hazard as advised by the NSHM 2022 for entire New Zealand, there is a huge demand for the retrofit of existing building stock to achieve higher earthquake resilience. One of the ways to achieve a ... -
Investigating the effect of stiffness on the seismic performance of RC structures
(2023-04-19)This study investigates the correlation between stiffness and the seismic performance of RC structures. Structural performance was compared for buildings affected by four different earthquakes, Tokachi-Oki (1968), Chile ... -
Source of numerical non-convergence in the analysis of bilinear SDOF systems
(2023-04-19)Numerical non-convergence is an important factor impeding the research into and widespread adoption of the nonlinear dynamic analysis. Upon encountering non-convergence at an analysis time step when using an implicit time ... -
How to assemble elemental damping?
(2023-04-19)An elemental damping model has recently been proposed as an alternative to the Rayleigh damping model to avoid spurious damping forces during inelastic seismic response. It has shown great potential because it has the ... -
Site-specific seismic hazard analysis - evolving developments in practice
(2023-04-19)Site-specific hazard analyses (SSHAs) are undertaken to inform seismic actions for the design of important projects in New Zealand. These have typically adopted the 2010 National Seismic Hazard Model (NSHM) as the reference ... -
International alignment and update of the New Zealand earthquake intensity scale
(2023-04-19)The New Zealand Modified Mercalli intensity (MMI) scale was last revised in 2008. Even so, the scale's lack of specificity on New Zealand's structures for MMI>8 intensity levels has made it difficult to assign values for ... -
GeoNet’s Shaking Layer Tool: Generation of near-real time ground shaking for post-event response
(2023-04-19)Information on ground shaking following an earthquake is important for many applications from emergency response, engineering assessments, infrastructure management, insurance claim estimation and research. GeoNet, along ... -
