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 ...
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 ...
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. ...
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, ...
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 ...
Experimental study on structural performance and damage characteristics of repaired flexural RC members
(New Zealand Society for Earthquake Engineering, 2023-04-19)
Understanding the expected seismic performance recovery of repaired members is important to make an effective recovery plan for damaged buildings. In this research, three RC beam and three RC wall specimens were subjected ...
How to assemble elemental damping?
(New Zealand Society for Earthquake Engineering, 2023-04-19)
An elemental damping model has recently been proposed as an alternative to the Rayleigh damping model to avoid spurious damping forces during inelastic seismic response. It has shown great potential because it has the ...
Chevron Buckling Restrained Brace Frame Seismic Behaviour Considering Out-of-Plane Effects
(New Zealand Society for Earthquake Engineering, 2023-04-19)
This project evaluates the behaviour of buckling restrained braces (BRBs) in a chevron configuration considering IP and OOP frame deformations using software capable of second-order inelastic frame analysis. Initially a ...
