Elastic Design (μ=1.0) of Damage Avoidance Structures
(New Zealand Society for Earthquake Engineering, 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 ...
Code requirements for column confinement with a view on drift
(New Zealand Society for Earthquake Engineering, 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
(New Zealand Society for Earthquake Engineering, 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 ...
Assessing the impact of acceleration-sensitive components on the seismic losses of multi-storey office buildings
(New Zealand Society for Earthquake Engineering, 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 ...
Retaining Wall Design - SESOC
(New Zealand Society for Earthquake Engineering, 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 ...
Reclamation resilience improvement at CentrePort, Wellington New Zealand
(New Zealand Society for Earthquake Engineering, 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 ...
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 ...
