Earthquake Design Loads on Retaining Walls
(New Zealand Society for Earthquake Engineering, 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 ...
Seismic Performance of Precast Hollow-core Units Seated Within the Plastic Hinge Region
(New Zealand Society for Earthquake Engineering, 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 ...
Repair and Reinstatement of Douglas-fir CLT Hold-down Connections using Mixed Angle Self Tapping Screws
(New Zealand Society for Earthquake Engineering, 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 ...
Prediction of Demands on Non-Structural Components in Base-Isolated Structures
(New Zealand Society for Earthquake Engineering, 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 ...
Geotechnical challenges and design solutions for Yarrow Stadium redevelopment
(New Zealand Society for Earthquake Engineering, 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 ...
Experimental and analytical evaluation of different failure modes of self-centring braces
(New Zealand Society for Earthquake Engineering, 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 ...
Application of resilient rocking cores in low damage mass timber structures: A case study
(New Zealand Society for Earthquake Engineering, 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, ...
A preliminary investigation of validity of conventional single-mode pushover analysis in multi-mode systems
(New Zealand Society for Earthquake Engineering, 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 ...
Seismic response of a base-isolated building under pulse-like near-fault ground motions
(New Zealand Society for Earthquake Engineering, 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 ...
Risk-targeted framework for seismic design: Maintaining serviceability
(New Zealand Society for Earthquake Engineering, 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 ...
