Investigation of vertical reinforcement termination in lightly reinforced concrete walls
(2021-04-14)Reinforced concrete (RC) structural walls are effective lateral force-resisting components commonly implemented in tall buildings. Recent studies have investigated the impact of minimum vertical reinforcement limits on the ... -
Improving earthquake resilience in the Taupō Volcanic Zone (TVZ) using school-based seismometers and connected education programmes
(2021-04-14)Over the past decade several “seismometers in schools” programmes have been developed in Aotearoa New Zealand by a range of organisations, for a variety of reasons and aiming to achieve a range of educational outcomes. ... -
The top enablers and barriers of seismic technology adoption in construction
(2021-04-14)The slow process of adoption of the new technologies has been identified as a significant issue in the construction industry. In order to address this issue, the top enablers and barriers of the adoption process are needed ... -
Quantifying the Embodied Carbon Cost from Demolitions Following the Canterbury Earthquakes
(2021-04-14)The 2010/2011 Canterbury Earthquake Sequence resulted in severe financial loss, loss of life and disruption in Christchurch due to liquefaction and damage from strong shaking, which led to the widespread displacement of ... -
Full Waveform Tomography for the upper South Island region, New Zealand
(2021-04-14)In this paper, we apply Full Waveform Tomography (FWT) based on the Adjoint-Wavefield (AW) method to iteratively invert an existing 3-D geophysical velocity model for the upper South Island region, New Zealand. Through the ... -
Philosophical reflexions following the Lyttleton 2011 New Zealand Earthquake: Ten years after
(2021-04-14)At 12:51 p. m. on 22 February 2011, the Mw 6.3 Lyttelton earthquake struck the Canterbury region of New Zealand. The seismic event was reported as the result of the rupture of a previously unknown geological fault, 5.9 km ... -
A comparison of New Zealand seismic code requirements with other major design codes in the implementation of seismic resilient devices
(2021-04-14)In the ever-evolving earthquake engineering field, the need of the hour is to achieve earthquake-resistant buildings which have immediate occupancy following an earthquake. This implies that the demand for resilient dampers ... -
Seismic upgrading of friction-damped steel frames integrated with self-centring devices
(2021-04-14)Conventional friction-based damping devices are known for their large energy dissipation capacity and economic benefits compared to other seismic mitigation systems. These devices have been implemented in many practical ... -
Identifying attributes influencing failure mechanisms in unreinforced masonry buildings using machine learning
(2021-04-14)Unreinforced masonry buildings comprise a major part of New Zealand's built heritage and were significantly damaged during the 2010-2011 Canterbury Earthquake sequence. There were 627 URM building assessed in the surveys ... -
Dras Fault: a major active fault in Kashmir Himalaya
(2021-04-14)Previous works have shown that the oblique tectonic convergence between the lithospheric plates of India and Eurasia in NW Himalaya is primarily manifested by the formation of a series of fold- and thrustbelts, and the ... -
Hazard-consistent collapse risk assessment of steel moment frame buildings in Wellington
(2021-04-14)This study evaluates the seismic collapse risk of two modern ductile steel moment frame buildings designed as per the NZS 1170.5 seismic design standard. A four and twelve storey steel moment frame buildings located in ... -
Shake table testing of fire sprinkler piping systems typical of New Zealand practices
(2021-04-14)An automatic fire sprinkler piping system requires an intricate piping network to feed individual sprinklers spread across the plenum space. In practice, this elaborate piping network is braced against seismic demands ... -
Numerical modelling of a concrete wall-steel frame building
(2021-04-14)Buildings that use concrete walls together with steel frames have become increasingly common in Christchurch, with around 35% of post-earthquake buildings using such mixed-material structural systems. This rapid shift in ... -
Are stronger, stiffer buildings indeed costlier?: Case study of RC frame buildings
(2021-04-14)Seismic codes/standards allow buildings to be designed for different lateral strength as long as the associated ductility and drift demands are catered for. The design seismic force is primarily controlled by a force ... -
Parallel scalability of OpenSees for 2D and 3D ground response analysis problems
(2021-04-14)This study investigates the parallel scalability of the OpenSees finite element analysis platform in the context of 2D and 3D ground response analyses. A series of 2D and 3D models ranging from 7500 to 480000 elements are ... -
A holisic methodology for assessing post-earthquake hospital functionality
(2021-04-14)Hospitals play a critical role in ensuring community safety. Hospitals must remain operational during and after an earthquake. However, physical damage, utility outages, or supply shortages can cause closures and/or ... -
Factors affecting the balancing of Gender Representation in the Engineering Industry
(2021-04-14)Gender disparity in the engineering industry is a well-recognised problem. Engineering is a growing industry, and the lack of gender balance affects the diversity of thought available to it, as well as the potential ... -
Liquefaction Risk Analysis of Native and Reclaimed Soil Deposits in Central Wellington
