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
(2023-04-19)The important role of bridges in transportation network resiliency has made the management of the existing bridge stock an essential task. In order to implement and prioritise the activities to secure the proper performance ... -
