Wellington Children’s Hospital - a different approach to a seismic restraint project
(New Zealand Society for Earthquake Engineering, 2023-04-19)
The seismic restraint design for non-structural elements in the new, Importance Level 3, Wellington Childrens Hospital building utilised a considered and efficient design approach that minimise the number of seismic ...
A New Rocking Concrete Shear Wall with Self-Centring Friction Connections
(New Zealand Society for Earthquake Engineering, 2023-04-19)
In recent years, the intention towards developing and utilising low-damage systems in seismic resisting structures has been increasing amongst researchers and engineers. Replaceability and repairability after earthquakes ...
Seismic design of suspended lightweight ceilings – what’s the ductility?
(New Zealand Society for Earthquake Engineering, 2023-04-19)
In the last few years, the design of suspended ceilings has gone through significant change and the level of compliance required has increased substantially. This was largely due to the generally poor performance of these ...
Design Considerations for Buckling Restrained Braces in Timber Frames Subject to Out of Plane Deformations
(New Zealand Society for Earthquake Engineering, 2023-04-19)
The introduction of using steel buckling restrained braces (BRBs) has proven to greatly improve the in-plane seismic performance of timber structures. However, little is understood about the performance of BRBs subject to ...
Evaluation of prioritization schemes for bridge stock assessment
(New Zealand Society for Earthquake Engineering, 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 ...
A Review of the State of Practice for Fluid Viscous Damper Applications in North America and New Zealand
(New Zealand Society for Earthquake Engineering, 2023-04-19)
The use of Fluid Viscous Dampers (FVDs) for retrofit and new construction applications is growing around the world. FVDs provide an effective way to reduce seismic demands on structures. In retrofit applications, this ...
Area Ratio or Volumetric Ratio: Which is better for quantifying the confinement of concrete?
(New Zealand Society for Earthquake Engineering, 2023-04-19)
Confinement of concrete helps in improving ultimate strain of concrete. This increase depends on amount of transverse reinforcement in the vertical member. While the need for 1350 hooks in transverse reinforcement is ...
Vs30 Assessments: Understanding the Underground
(New Zealand Society for Earthquake Engineering, 2023-04-19)
Understanding the vulnerability of a construction site to seismic shaking is fundamental to robust building design in New Zealand. The recent release of the updated National Seismic Hazard Model reflects this, with an ...
Using 3D geological models to create maps of estimated Vs30 and site period
(New Zealand Society for Earthquake Engineering, 2023-04-19)
The 30-m time-averaged shear-wave velocity (Vs30) and the fundamental site period (T0) are useful parameters for understanding site conditions, informing geotechnical studies as well as infrastructure planning. Unfortunately, ...
Innovative Retrofit Solution for Exterior Unreinforced R.C. Beam-Column Joints
(New Zealand Society for Earthquake Engineering, 2023-04-19)
Most reinforced concrete (RC) frame buildings in New Zealand constructed pre-1960s have unreinforced beam-column joints. Following MBIE/NZSEE assessment guidance, the seismic performance of RC frames with unreinforced ...
