Directing Low-Damage Seismic Design with Building Functionality
(New Zealand Society for Earthquake Engineering, 2021-04-14)
The upcoming New Zealand Low-Damage Seismic Design (LDSD) guidance information, currently in preparation, is widely anticipated to provide a reference point for aligning low-damage seismic performance targets. A key aspect ...
Quantifying the Embodied Carbon Cost from Demolitions Following the Canterbury Earthquakes
(New Zealand Society for Earthquake Engineering, 2021-04-14)
The 2010/2011 Canterbury Earthquake Sequence resulted in severe financial loss, loss of life and disruption in Christchurch due to liquefaction and damage from strong shaking, which led to the widespread displacement of ...
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 ...
Advances in Floor Diaphragm In-Plane Modelling Using Truss Elements
(New Zealand Society for Earthquake Engineering, 2021-04-14)
Different methods to model building floor diaphragm in-plane stiffness with truss elements are compared to identify the method most suitable for analysis in design. The methods considered include (i) Elastic truss, (ii) ...
1170.5 Reimagined: from a structural designers view
(New Zealand Society for Earthquake Engineering, 2021-04-14)
Our loadings code has adapted and extended to incorporate new knowledge as it has emerged over the last 50+ years: could a re-write encourage engineers to design better buildings? This paper outlines some intentionally ...
Depth and Shape of the Basement Surface Beneath Wellington City, Based on Gravity and Seismic Constraints
(New Zealand Society for Earthquake Engineering, 2022-04-27)
A new basin-depth map for the Wellington Central Business District shows a maximum depth of 540 m near the Wellington Stadium. This is twice that previously proposed. Our new basin geometry constraints are from a residual ...
Elastic Design (μ=1.0) of Damage Avoidance Structures
(New Zealand Society for Earthquake Engineering, 2022-04-27)
Damage Avoidance Design (DAD) has been considered an efficient way for seismic design. Different solutions to achieve a robust DAD structure has been proposed and tested by researchers in the past. However, there is a lack ...
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 ...
Code requirements for column confinement with a view on drift
(New Zealand Society for Earthquake Engineering, 2022-04-27)
Confinement provided by transverse reinforcement plays an essential role in reinforced concrete columns. When proportioned judiciously, confinement provides longitudinal bar restraint, contributes to shear resistance, and ...
Interim Results from empirical ground motion model evaluation for the NZ National Seismic Hazard Model Update
(New Zealand Society for Earthquake Engineering, 2022-04-27)
As a part of the ongoing 2022 NZ National Seismic Hazard Model (NSHM) Update, the predictive capabilities of candidate empirical ground motion models are evaluated to ascertain models which provide good prediction for NZ ...
