Deformability of lap splices in RC structural walls
(2023-04-19)Severe structural damage associated with lap splices located near the foundation of reinforced concrete (RC) structural walls has been recorded in the field after recent major earthquakes in Chile, New Zealand, and Taiwan. ... -
Design Considerations for Buckling Restrained Braces in Timber Frames Subject to Out of Plane Deformations
(2023-04-19)The introduction of using steel buckling restrained braces (BRBs) has proven to greatly improve the in-plane seismic performance of timber structures. However, little is understood about the performance of BRBs subject to ... -
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 ... -
Developing Construction 4.0 transformation of Aotearoa New Zealand's construction sector
(2023-04-19)Aotearoa’s construction industry reached over $20.5 billion in 2019 and it became the fourth largest workplace in the year ended June 2021, significantly contributing to New Zealand’s economy. However, it has long been ... -
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 ... -
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 ... -
Dynamic analysis of tall reinforced concrete walls designed with minimum vertical reinforcement
(2023-04-19)Analysis of tall walls subjected to the earthquake ground motions highlights the amplified dynamic moment response at the mid-height due to the higher mode effect. The amplified moment demand may result in unexpected ... -
Dynamic Behaviour of Interlocking Plastic-block Structure Using Shake Table
(2023-04-19)Severe damage was caused by the earthquake, primarily to non-engineered structures in rural areas. Structures including roads, bridges, buildings and railroad tracks all suffered catastrophic destruction as a result of ... -
Earthquake Design Pressures from Soil Interaction on Building Basement Walls
(2023-04-19)Free-standing retaining walls are usually designed for earthquake loads using the Mononobe-Okabe method and assuming cohesionless soil backfill. The method assumes active pressure develops as a consequence of a failure ... -
Earthquake Protection of Residential Buildings: New Resilient System for Light Timber Framing
(2023-04-19)In NZ, similar to other countries, residential houses are mostly constructed using light timber framing. The common seismic solutions available in the market for such low-rise buildings are based on yielding of sacrificial ... -
Earthquake strengthening clay brick masonry parapets – proof-tested solutions
(2023-04-19)Unrestrained unreinforced clay brick masonry (URM) parapets are found atop of a large number of vintage URM buildings. Parapets are typically cantilevered wall structural elements that form decorative and ornamental features ... -
Effect of Periodic Unit Cell Volume on Attenuation Zones of 1D-Meta-material based Periodic Foundations
(2023-04-19)The meta-material-based periodic foundations are being investigated by researchers for earthquake engineering applications due to their wave-filtering ability. The periodic foundations are characterized by frequency bandgaps, ... -
Effect of serviceability and over-strength mechanism on seismic response of low damage structures
(2023-04-19)Low-damage structural systems are designed in a way the earthquake damage is controlled and localised in pre-designated locations and components (e.g. fuses). These components are normally replaced, repaired or designed ... -
Effect of uncertainties in collapse assessment of coupled CLT walls with energy dissipators as couplers and resilient hold-downs
(2023-04-19)Rocking coupled CLT walls with energy dissipaters as couplers provide increased stiffness and damping, enabling the design realisation of taller CLT structures. Researchers have proposed design methods and conducted ... -
Elongating plastic hinge element for nonlinear analysis of RC structures using OPENSEES
(2023-04-19)During inelastic cyclic loading, the length of plastic hinges in reinforced concrete (RC) members increases irreversibly which significantly affects the seismic performance of RC structures. It is hence necessary for ... -
Enhancing earthquake and tsunami preparedness and response in Kura Kaupapa Māori/Schools in Tairāwhiti and Waiāriki, Aotearoa New Zealand
(2023-04-19)Aotearoa New Zealand is exposed to numerous potentially damaging impacts from various hazard events. The east coast of the North Island, one of the most active seismic regions in New Zealand, faces significant earthquake ... -
Establishing the Transverse Load Capacity of a Timber-framed Classroom Block
(2023-04-19)In 2013, longitudinal testing of single storey timber-framed classroom blocks was initiated by the Ministry of Education and completed by BRANZ to better understand the seismic resilience of timber-framed buildings within ... -
Estimates of site periods from mHVSR analysis of IRIS temporary seismograph networks
(2023-04-19)The effects of soil stratigraphy and sedimentary basins on earthquake ground shaking are well-established. These effects can be represented using a range of site metrics, with the focus of this paper being the fundamental ... -
Evaluation of prioritization schemes for bridge stock assessment
