Residential Building Repair Cost and Claim Settlement Time from the Canterbury Earthquake Sequence
(New Zealand Society for Earthquake Engineering, 2021-04-14)
This study analyses the Earthquake Commission’s (EQC) insurance claims database to investigate the influence of seismic intensity and property damage resulting from the Canterbury Earthquake Sequence (CES) on the repair ...
Performance comparison of standard and seismic glazing systems
(New Zealand Society for Earthquake Engineering, 2021-04-14)
Glazing systems are non-structural elements in a building that, more often than not, are given little consideration in seismic design. Recent experimental work into glazing systems at the University of Canterbury has shown ...
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 ...
Are stronger, stiffer buildings indeed costlier?: Case study of RC frame buildings
(New Zealand Society for Earthquake Engineering, 2021-04-14)
Seismic codes/standards allow buildings to be designed for different lateral strength as long as the associated ductility and drift demands are catered for. The design seismic force is primarily controlled by a force ...
Shake table testing of fire sprinkler piping systems typical of New Zealand practices
(New Zealand Society for Earthquake Engineering, 2021-04-14)
An automatic fire sprinkler piping system requires an intricate piping network to feed individual sprinklers spread across the plenum space. In practice, this elaborate piping network is braced against seismic demands ...
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 ...
Elongating plastic hinge element for nonlinear analysis of RC structures using OPENSEES
(New Zealand Society for Earthquake Engineering, 2023-04-19)
During inelastic cyclic loading, the length of plastic hinges in reinforced concrete (RC) members increases irreversibly which significantly affects the seismic performance of RC structures. It is hence necessary for ...
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 ...
