A Practical Approach to Design Supplemental Damped Isolation Systems
(New Zealand Society for Earthquake Engineering, 2023-04-19)
With an update to the NZS1170.5 design hazard expected in 2023, New Zealand designers will need innovative solutions in-order to manage potentially significant increases in design hazard, particularly around the lower North ...
Testing of heavily damaged reinforced concrete walls repaired using concrete and steel replacement
(New Zealand Society for Earthquake Engineering, 2023-04-19)
Post-earthquake damage assessments are essential to decisions on the need for and extent of structural repairs. Despite this, New Zealand currently has no official guidelines to evaluate the residual capacity of ...
Predictive models for changes in reinforcement characteristics due to strain ageing effects
(New Zealand Society for Earthquake Engineering, 2023-04-19)
One of the factors affecting repair feasibility of buildings damaged by earthquakes is the potential effects of strain ageing of reinforcement. Since strain ageing can lead to an increase in structural member strength and ...
Shaking Table Tests on RC Frames strengthened with Simplified Friction Damper
(New Zealand Society for Earthquake Engineering, 2023-04-19)
This study investigates the behavior of two reinforced concrete (RC) frames strengthened with simplified friction damper subjected to dynamic loading conditions. The simplified friction damper was designed with intent to ...
Feasibility of capacity spectrum method for analysis of low damage structural systems with friction connections
(New Zealand Society for Earthquake Engineering, 2023-04-19)
The use of friction connections for low damage design of new structures has been increasing over the past few years. These connectors have a high energy dissipation ratio and are relatively economical to fabricate and ...
Seismic Restraint of Non-Structural Elements – Evolving Design Thinking
(New Zealand Society for Earthquake Engineering, 2023-04-19)
Seismic Restraint of non-structural elements has received increased attention in the past decade within the New Zealand building industry. Clients and Project Managers are now often coupling Seismic Restraint design with ...
Dynamic analysis of tall reinforced concrete walls designed with minimum vertical reinforcement
(New Zealand Society for Earthquake Engineering, 2023-04-19)
Analysis of tall walls subjected to the earthquake ground motions highlights the amplified dynamic moment response at the mid-height due to the higher mode effect. The amplified moment demand may result in unexpected ...
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 ...
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 ...
