Wellington Children’s Hospital - a different approach to a seismic restraint project
(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
(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?
(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
(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
(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
(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?
(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
(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
(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
(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 ... -
Seismic design for temporary works: Recommendations for a Temporary Works forum NZ design note
(2023-04-19)The Temporary Works forum NZ (TWf NZ) aims to improve construction safety by addressing risk in the design and execution of temporary works. Anecdotal evidence suggests that seismic actions on temporary works are often ... -
Numerical parametric analysis of gravity column base-plate connections
(2023-04-19)Gravity column base-plate connections are normally treated as pinned connections in design. Correspondingly, a low rotational stiffness value is specified in the New Zealand steel design standard, NZS 3404. However, previous ... -
Performance assessment of shallow founded buildings on liquefiable soils
(2023-04-19)In evaluating foundation options for sites featuring liquefiable soils, shallow raft foundations may remain a suitable and preferred solution, provided the seismic performance can be demonstrated to be adequate. In evaluating ... -
Advanced seismic design of concrete-to-concrete structural connections
(2023-04-19)Seismic strengthening of concrete buildings and bridges may require the addition of new concrete members or overlays. One way of connecting new concrete to existing concrete is using post-installed rebar (PIR) connections. ... -
Liquefaction induced kinematic loads on piles and inertia loads - literature review and recommendations for design
(2023-04-19)Earthquake shaking can cause soil liquefaction in certain types of soil. The associated loss of soil strength and stiffness coupled with any lateral ground movement can be damaging to buildings and their foundations. Pile ... -
A Review of Practice-Oriented Methods for Estimating Seismic Demands on Parts and Components
(2023-04-19)A variety of methods for the estimation of demands on building parts and components have been proposed in international codes and the literature. These have been reviewed as part of recent research co-funded by QuakeCoRE, ... -
Optimisation through an Alternative Solution approach to incorporating soil-structure interaction
(2023-04-19)The New Zealand Building Code is performance based. However, the most commonly adopted design methods utilise capacity-based Verification Methods such as B1/VM1. Although considerable time and cost is typically associated ... -
Avoiding moat wall pounding of base-isolated buildings using D3 viscous dampers
(2023-04-19)Base-isolated buildings are typically important facilities expected to remain functional after a major earthquake. Seismically isolated buildings can experience large displacements at the isolation level during strong ... -
Lincoln University Waimarie building: An application of friction damping devices with recentring for low damage design
(2023-04-19)The experience from Christchurch and Kaikoura seismic events demonstrated well that the ‘life safety’ criteria is not sufficient to protect the community from earthquake impact. Currently, the community expects more measures ... -
Effect of serviceability and over-strength mechanism on seismic response of low damage structures
(2023-04-19)Low-damage structural systems are designed in a way the earthquake damage is controlled and localised in pre-designated locations and components (e.g. fuses). These components are normally replaced, repaired or designed ...
