High capacity glued-in rod connections in Cross-Laminated Timber (CLT) structures
(2023-04-19)Glued-in rods are efficient and high-capacity connections for achieving high-strength connections in new timber structures and reinforcing existing timber buildings. With the emergence of cross-laminated timber (CLT) and ... -
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 ... -
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 ... -
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 ... -
Innovative Retrofit Solution for Exterior Unreinforced R.C. Beam-Column Joints
(2023-04-19)Most reinforced concrete (RC) frame buildings in New Zealand constructed pre-1960s have unreinforced beam-column joints. Following MBIE/NZSEE assessment guidance, the seismic performance of RC frames with unreinforced ... -
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 ... -
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 ... -
Learning Importance Sampling Distributions via Normalizing Flows to Estimate Rare-Event Failure Probabilities
(2023-04-19)Engineered systems are typically designed to be robust and have very low probabilities of failure. However, developing accurate estimates of these probabilities can be challenging given the complex (and typically nonlinear) ... -
Lincoln University Waimarie building: An application of friction damping devices with recentring for low damage design
(2023-04-19)The experience from Christchurch and Kaikoura seismic events demonstrated well that the ‘life safety’ criteria is not sufficient to protect the community from earthquake impact. Currently, the community expects more measures ... -
Liquefaction induced kinematic loads on piles and inertia loads - literature review and recommendations for design
(2023-04-19)Earthquake shaking can cause soil liquefaction in certain types of soil. The associated loss of soil strength and stiffness coupled with any lateral ground movement can be damaging to buildings and their foundations. Pile ... -
Low Damage Wall To Floor Connections For Seismic Resilient Timber Structures
(2023-04-19)Rocking timber walls provide superior seismic performance in comparison with conventional light timber structures. Nevertheless, there is an uplift movement at the base of the wall that is translated as vertical displacement ... -
Meet EDDIE – QuakeCoRE’s new earthquake test dummy
(2023-04-19)Until recently there has been limited understanding of the relationship between behaviour during earthquake shaking and risk of injury. Studying human behaviour during shaking is important, however, because with a better ... -
Method for the explicit consideration of ground motion duration in NZS 1170.5
(2023-04-19)Recent studies have demonstrated that longer earthquake ground motion duration can reduce structural deformation capacity and increase collapse risk. This study introduces a method to explicitly account for such effects ... -
Mitigation of liquefaction-induced lateral spread ground displacements using an in-ground pile wall
(2023-04-19)Liquefaction-induced lateral spread ground displacements can be damaging to buildings and their foundations. Buildings can either be designed/strengthened to tolerate such displacements, or ground improvement (e.g. compaction, ... -
“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 ... -
Modelling of residential house perimeter foundation beams subjected to ground deformations
(2023-04-19)The 2010-11 Canterbury earthquake sequence is the most damaging and disruptive seismic event to affect New Zealand, resulting in repair costs totalling approximately NZ$40 billion. Liquefaction induced ground deformations ... -
Multidirectional cyclic testing of self-centering cross-laminated timber shear wall sub-assemblies
(2023-04-19)Driven by demand for sustainable buildings, mass timber, specifically cross-laminated timber (CLT), is being more widely used in mid-rise buildings in the US. In areas of the US with a significant seismic (i.e., earthquake) ... -
Multistage Friction Connections
(2023-04-19)Multistage friction connections (MFCs) are bolted connections for dissipating seismic energy while reducing peak displacements and encouraging recentring. MFCs comprise two symmetric friction connections co-linearly ... -
Numerical Investigation of Australasian Cold-Formed Steel strap-braced walls under lateral and vertical load
(2023-04-19)Cold-Formed Steel (CFS) gained popularity in residential buildings due to its dimensional accuracy, lightweight, resistance to shrinking and creeping, durability, low embodied carbon and CNC manufacturing abilities. The ... -
Numerical parametric analysis of gravity column base-plate connections
(2023-04-19)Gravity column base-plate connections are normally treated as pinned connections in design. Correspondingly, a low rotational stiffness value is specified in the New Zealand steel design standard, NZS 3404. However, previous ...
