Identifying vulnerable reinforced concrete buildings in Wellington using a simple assessment methodology
(New Zealand Society for Earthquake Engineering, 2021-04-14)
The application of a simple yet effective method to assess reinforced concrete buildings in New Zealand is discussed. It is proposed that this method be used to identify and prioritise the most vulnerable reinforced concrete ...
Strength requirements for non-structural components responding nonlinearly under earthquake excitation
(New Zealand Society for Earthquake Engineering, 2021-04-14)
This study develops a practice-oriented method to design non-structural components and their restraints to lower strengths than needed to remain elastic under earthquake ground motion by permitting nonlinear non-structural ...
Validation of NZ small-magnitude ground-motion simulations using complex structural systems
(New Zealand Society for Earthquake Engineering, 2021-04-14)
This study assesses the need to consider complex structural models in ground-motion simulation validation. It develops a novel statistical framework to quantify the proportion of the differences in structural responses ...
Hazard-consistent collapse risk assessment of steel moment frame buildings in Wellington
(New Zealand Society for Earthquake Engineering, 2021-04-14)
This study evaluates the seismic collapse risk of two modern ductile steel moment frame buildings designed as per the NZS 1170.5 seismic design standard. A four and twelve storey steel moment frame buildings located in ...
Incorporating the influence of duration on dynamic deformation capacity in seismic assessment
(New Zealand Society for Earthquake Engineering, 2021-04-14)
The dynamic deformation capacity of a structure is the peak storey drift ratio it can safely withstand without collapsing due to dynamic instability. In a previous study, the authors developed a robust procedure to compute ...
Modelling uncertainty induced by plastic hinge length in lumped-plasticity analysis of RC columns
(New Zealand Society for Earthquake Engineering, 2022-04-27)
This study quantifies the influence of various plastic hinge length assumptions on the uncertainty in the response of reinforced concrete (RC) columns simulated using lumped plasticity models. Although several expressions ...
Prediction of Demands on Non-Structural Components in Base-Isolated Structures
(New Zealand Society for Earthquake Engineering, 2022-04-27)
This study examines seismic demands imposed on non-structural components within base isolated structures. Although several previous studies have focussed on the ability of base isolators to limit structural damage, very ...
Modelling the out-of-plane buckling behaviour of BRBFs
(New Zealand Society for Earthquake Engineering, 2022-04-27)
The objective of this study is to assess the impact of modelling the out-of-plane buckling behaviour of buckling-restrained braced frames (BRBFs) on their estimated seismic performance. A number of recent studies have ...
Investigating the effect of stiffness on the seismic performance of RC structures
(New Zealand Society for Earthquake Engineering, 2023-04-19)
This study investigates the correlation between stiffness and the seismic performance of RC structures. Structural performance was compared for buildings affected by four different earthquakes, Tokachi-Oki (1968), Chile ...
Development, verification, and validation of a buckling-fatigue steel material model
(New Zealand Society for Earthquake Engineering, 2023-04-19)
Currently, there are limited constitutive models available in finite element analysis packages that reliably capture the coupled effects of bar buckling and fatigue. However, such a model is needed for reliable estimation ...
