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 ... -
Low Damage Wall To Floor Connections For Seismic Resilient Timber Structures
(2023-04-19)Rocking timber walls provide superior seismic performance in comparison with conventional light timber structures. Nevertheless, there is an uplift movement at the base of the wall that is translated as vertical displacement ... -
“Modal crimes” in structural engineering
(2023-04-19)With increasing seismic hazard as advised by the NSHM 2022 for entire New Zealand, there is a huge demand for the retrofit of existing building stock to achieve higher earthquake resilience. One of the ways to achieve a ... -
Multidirectional cyclic testing of self-centering cross-laminated timber shear wall sub-assemblies
(2023-04-19)Driven by demand for sustainable buildings, mass timber, specifically cross-laminated timber (CLT), is being more widely used in mid-rise buildings in the US. In areas of the US with a significant seismic (i.e., earthquake) ... -
Numerical Investigation of Australasian Cold-Formed Steel strap-braced walls under lateral and vertical load
(2023-04-19)Cold-Formed Steel (CFS) gained popularity in residential buildings due to its dimensional accuracy, lightweight, resistance to shrinking and creeping, durability, low embodied carbon and CNC manufacturing abilities. The ... -
Optimum service and seismic structural protection with adaptive dampers and base isolators for immediate occupancy after the earthquake
(2023-04-19)To improve serviceability of important civil structures during seismic action, base isolators and dampers need to perform with high efficiency independent of the ground shaking level. In service and seismic actions, base ... -
Predictive models for changes in reinforcement characteristics due to strain ageing effects
(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 ... -
Response of Retrofitted 3D RC Frames under Dynamic Loading Conditions
(2023-04-19)In this study, the response of 3D double story reinforced concrete (RC) frames retrofitted through a diagonal friction damper under dynamic loading conditions, was evaluated using shaking table tests. A friction damper ... -
Review and suggestions on timber buildings with hybrid lateral force resisting systems
(2023-04-19)Timber-framed structures have long been the default structural form for residential construction in many countries, including New Zealand. However, for some complex low-rise and mid-rise buildings, hybrid Lateral Force ... -
Seismic application of fillet and partial penetration butt welds
(2023-04-19)Fillet and partial (incomplete) penetration butt welds are the most cost-effective weld details for structural steel connections. Correctly sized and executed, double-sided, balanced fillet welds and partial penetration ... -
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 ... -
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 ... -
Seismic Restraint of Non-Structural Elements – Evolving Design Thinking
(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 ... -
Shake-table testing of resilient, low-cost seismic isolators based on rolling rubber spheres
(2023-04-19)This study presents the results of a large-scale experimental investigation of resilient, low-cost seismic isolators based on deformable rubber spheres. The isolators roll on flat or spherical (concave) concrete surfaces. ... -
Shaking Table Tests on RC Frames strengthened with Simplified Friction Damper
(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 ... -
Testing of heavily damaged reinforced concrete walls repaired using concrete and steel replacement
(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 ...
