Seismic design for temporary works: Recommendations for a Temporary Works forum NZ design note
(New Zealand Society for Earthquake Engineering, 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
(New Zealand Society for Earthquake Engineering, 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
(New Zealand Society for Earthquake Engineering, 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
(New Zealand Society for Earthquake Engineering, 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
(New Zealand Society for Earthquake Engineering, 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
(New Zealand Society for Earthquake Engineering, 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
(New Zealand Society for Earthquake Engineering, 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
(New Zealand Society for Earthquake Engineering, 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
(New Zealand Society for Earthquake Engineering, 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
(New Zealand Society for Earthquake Engineering, 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 ...
