Development of statistical downscaling model based on Volterra series realization, principal components and ridge regression
A new statistical approach combining principal component analysis (PCA) and ridge regression provides better models of climate change impacts.
Building collapse due to P-delta – what is the risk?
Sullivan, T.J., De Francesco, G. 2024 Building collapse due to P-delta – what is the risk? NZSEE 2024 Annual Conference, Wellington, Paper 53.
Fracture of beam-column connections with cope holes under large cyclic deformations
Strong earthquake shaking of steel structures can impose significant cyclic demands on steel elements, leading to fracture and collapse. This study describes the use, calibration, and verification of models to describe the 'ductile fracture' behaviour of steel components subjected to large displacement cycles.
Modelling of residential house perimeter foundation beams subjected to ground deformations
This study evaluates the behaviour of several perimeter foundation beam sections subjected to liquefaction-induced ground deformations, and considers damage implications for the house above.
Quasi-Static Cyclic Testing of a Drift-Sensitive Sub-Assembly of Non-Structural Elements with Low-Damage Characteristics
Testing the seismic performance of a new precast concrete cladding system as a low-damage alternative to conventional systems.
Assessment of the torsional behaviour of hollow core slabs
This paper extends the applicability of a previously proposed finite-element modelling approach, to help improve the understanding of the torsional behavior of precast pre-stressed hollow-core concrete slabs.
Creating a ‘planning emergency levels of service’ framework – a silver bullet, or something useful for target practice?
Considerations for the development of Planning Emergency Levels of Service (PELOS) frameworks.
Indicator-based resilience assessment of stormwater infrastructure network structure
Stormwater systems rely on an acyclic structure, making networks more vulnerable. This paper introduces a new framework to characterise the resilience of acyclic network structures.
Shallow groundwater characterisation and hydrograph classification in the coastal city of Ōtautahi/Christchurch, New Zealand
This study investigates spatial and temporal trends in groundwater depth, and the relationship to natural and anthropogenic stressors, using a case-study in Ōtautahi/Christchurch, New Zealand.
A new mapping tool to visualise critical infrastructure levels of service following a major earthquake
R. Mowll, M. Anderson, T. Logan, J. Becker, L. Wotherspoon, C. Stewart, D. Johnston, D. Neely 2024 A new mapping tool to visualise critical infrastructure…
Modelling national residential building exposure to flooding hazards
Building construction in flood hazard areas peaked from 1960 – 1980 while total floor area and replacement value has continued to increase.
Comparison of seismic performance on plasterboard bracing walls and plywood shear walls in the context of New Zealand light timber-framed structures
In most New Zealand homes, plasterboard-bracing walls form the main lateral load-resisting system. This study compares seismic performances of plasterboard-bracing walls and plywood-sheathed walls.
