A bespoke analytical methodology for seismic safety assessment of spillway gates: case study of Waipapa dam spillway on the Waikato River
(2022-04-27)This paper presents a seismic assessment methodology tailor-made for the Waipapa Dam Spillway gates on the Waikato River which were found to have potential dam safety issues under the 1 in 2500-year annual exceedance ... -
A preliminary investigation of validity of conventional single-mode pushover analysis in multi-mode systems
(2022-04-27)Pushover analysis is a simplified inelastic analysis approach where a structure is subjected to increasing increments of monotonic imposed force or displacements to estimate the inelastic deformations in the structural ... -
Application of resilient rocking cores in low damage mass timber structures: A case study
(2022-04-27)The application of mass timber structures made with massive wooden panels such as Cross Laminated Timber (CLT) has significantly increased in the last few years owing to their many architectural and structural advantages, ... -
Assessing the impact of acceleration-sensitive components on the seismic losses of multi-storey office buildings
(2022-04-27)The Ministry of Building, Innovation and Employment is developing advice on how to deliver Low Damage Seismic Design (LDSD) protection for buildings through their Tū Kahika: Building Resilience platform. A preliminary ... -
Code requirements for column confinement with a view on drift
(2022-04-27)Confinement provided by transverse reinforcement plays an essential role in reinforced concrete columns. When proportioned judiciously, confinement provides longitudinal bar restraint, contributes to shear resistance, and ... -
Ductility factor validation for CLT walls with bolted hold-downs: preliminary analysis and observations
(2022-04-27)High-capacity cantilever CLT walls can be created with bolted hold-downs to resist earthquake loading. This study briefly presents the experimental results and cyclic behaviour of the representative test specimen. Then ... -
Earthquake Design Loads on Retaining Walls
(2022-04-27)Free-standing retaining walls are usually designed for earthquake loads using the Monobe-Okabe method and assuming cohesionless soil backfill. This simple design approach has led to satisfactory performance and is supported ... -
Elastic Design (μ=1.0) of Damage Avoidance Structures
(2022-04-27)Damage Avoidance Design (DAD) has been considered an efficient way for seismic design. Different solutions to achieve a robust DAD structure has been proposed and tested by researchers in the past. However, there is a lack ... -
Experimental and analytical evaluation of different failure modes of self-centring braces
(2022-04-27)As resilience of structures during seismic events is currently a main structural engineering topic, Low-damage self-centring braces have the potential to serve this purpose by becoming a common low-damage lateral load ... -
Geotechnical challenges and design solutions for Yarrow Stadium redevelopment
(2022-04-27)New Plymouth Yarrow Stadium’s two grandstands were declared earthquake-prone and closed in 2017-2018. The $50m repair and refurbishment project was approved in 2019 and subsequently reviewed and modified to allow for the ... -
Prediction of Demands on Non-Structural Components in Base-Isolated Structures
(2022-04-27)This study examines seismic demands imposed on non-structural components within base isolated structures. Although several previous studies have focussed on the ability of base isolators to limit structural damage, very ... -
Reclamation resilience improvement at CentrePort, Wellington New Zealand
(2022-04-27)CentrePort operations were significantly disrupted following damage to strategic assets sustained in the 2016 Kaikōura Earthquake, demonstrating the ports seismic vulnerability. Improved resilience is a necessity to long-term ... -
Repair and Reinstatement of Douglas-fir CLT Hold-down Connections using Mixed Angle Self Tapping Screws
(2022-04-27)The system ductility of timber structures under seismic loads relies on well detailed connection systems. With the increasing popularity of mass timber structures, CLT shear walls provide an efficient seismic load resisting ... -
Retaining Wall Design - SESOC
(2022-04-27)In the absence of a recognised or accepted national standard, and in order to provide clarity around the technical basis for their retaining wall software, some time ago SESOC embarked on the development of two design ... -
Risk-targeted framework for seismic design: Maintaining serviceability
(2022-04-27)Changes to how seismic loads are determined for building design are imminent, as necessitated by the ongoing National Seismic Hazard Model update. The authors recently proposed a framework to produce risk-targeted hazard ... -
Seismic Performance of Precast Hollow-core Units Seated Within the Plastic Hinge Region
(2022-04-27)This paper discusses the susceptibility of hollow-core floor units to sustain a higher degree of damage when they are seated within the plastic hinge regions of the supporting beam. This damageability of these so-called ... -
Seismic response of a base-isolated building under pulse-like near-fault ground motions
(2022-04-27)Pulse-Like Near-fault ground motions are known to challenge base-isolated buildings with their capacity to create large isolation system displacements. Such earthquake records typically contain velocity pulses with long ... -
Seismic structural monitoring in Wellington using advanced seismological techniques
(2022-04-27)Sklodowska et al. (2021) employed advanced seismological techniques usually applied to Earth studies to the Te Puni building (instrumented as part of the GeoNet building instrumentation programme) for the 2009-2017 ...
