A simple method to predict floor response spectral demands on nonstructural components
Haymes, Kieran; Sullivan, Timothy; Chandramohan, Reagan (2020-04-22)This paper summarises a newly proposed practice-oriented method to predict elastic floor acceleration response spectra for estimating demands on nonstructural components. The approach builds on previous contributions in ... -
Base isolated building preformance and the impact of the national seismic hazard model
Dong, Siqi (Claire); Sullivan, Timothy; Pettinga, Didier (2023-04-19)The NZSEE/MBIE recently released seismic design guidelines aiming to provide a more consistence design performance of base-isolated buildings in NZ. This paper confirms the superior performance of base-isolated buildings ... -
Developing guidelines for the seismic assessment of glazing systems
Arifin, Fransiscus; De Francesco, Giovanni; Sullivan, Timothy; Dhakal, Rajesh P. (2020-04-22)There is an increasing recognition that the seismic performance of buildings will be affected by the behaviour of both structural and non-structural elements. In light of this, work has been progressing at the University ... -
Estimating deformation demands on steel EBF systems
Yu, Fangshuo; Huang, Ruofan; Sullivan, Timothy (2020-04-22)The deformation capacity of a steel eccentrically braced frame (EBF) structure is typically governed by the chord rotation capacity of the EBF links. Codes allow these chord rotation demands to be estimated a variety of ... -
Experimental loading protocols to evaluate the seismic performance of floor systems
De Francesco, Giovanni; Sullivan, Timothy (2021-04-14)Major earthquakes, such as the Canterbury and Kaikoura events recorded in New Zealand in 2010 and 2016 respectively, highlighted that floor systems can be heavily damaged. At a reduced or full scale, quasi-static experimental ... -
Finite Element Analyses of Hollow Core Units Subjected to Shear and Torsion
Sarkis , Ana Isabel; Sullivan, Timothy (2021-04-14)A building boom in the 1980s allowed pre-stressed hollow-core floor construction to be widely adopted in New Zealand, even though the behaviour of these prefabricated elements within buildings was still uncertain. Inspections ... -
Incorporating the influence of duration on dynamic deformation capacity in seismic assessment
Bhanu, Vishvendra; Chandramohan, Reagan; Sullivan, Timothy (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 ... -
International alignment and update of the New Zealand earthquake intensity scale
Charleson, Andrew; Goded, Tatiana; Lin, Sheng-Lin; Beattie, Graeme; Ingham, Jason; Sullivan, Timothy; Hortacsu, Ayse; Wald, David (2023-04-19)The New Zealand Modified Mercalli intensity (MMI) scale was last revised in 2008. Even so, the scale's lack of specificity on New Zealand's structures for MMI>8 intensity levels has made it difficult to assign values for ... -
Investigating the impact of design criteria on the expected seismic losses of an office building
Williamson, Michael; John, Luis; Sullivan, Timothy (2021-04-14)Low Damage Seismic Design (LDSD) guidance material being developed by Engineering NZ is considering a design drift limit for multi-storey buildings of 0.5% at a new damage control limit state (DCLS). The impact of this new ... -
Investigation of the Plastic Drift Capacity of RC Frames with Beam-Column Joint Failure
Dong, Claire; Brunton, Jake; Sullivan, Timothy (2021-04-14)MBIE/NZSEE guidelines have various methods to assess existing buildings, of which Displacement Based Assessment (DBA) is one. This paper reports on the application of DBA to reinforced concrete (RC) frames where beam-column ... -
Method for the explicit consideration of ground motion duration in NZS 1170.5
Bhanu, Vishvendra; Chandramohan, Reagan; Sullivan, Timothy (2023-04-19)Recent studies have demonstrated that longer earthquake ground motion duration can reduce structural deformation capacity and increase collapse risk. This study introduces a method to explicitly account for such effects ... -
Modelling of residential house perimeter foundation beams subjected to ground deformations
Dawson, Max; Sullivan, Timothy; Millen, Maxim (2023-04-19)The 2010-11 Canterbury earthquake sequence is the most damaging and disruptive seismic event to affect New Zealand, resulting in repair costs totalling approximately NZ$40 billion. Liquefaction induced ground deformations ... -
Performance comparison of standard and seismic glazing systems
Arifin, Fransiscus Asisi; Sullivan, Timothy; Dhakal, Rajesh (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 ... -
Seismic Design and Analysis of a Medium Density Residential Building
Gribbon, Cameron; Jennings, Zayne; De Francesco, Giovanni; Sullivan, Timothy (2021-04-14)There is an increasing recognition that good seismic performance requires not only checks on life-safety but also limitation of damage, disruption and losses. In light of this, several proposals are currently being developed ... -
Shake table testing of fire sprinkler piping systems typical of New Zealand practices
Rashid, Muhammad; Dhakal, Rajesh; Sullivan, Timothy; Yeow, Trevor (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 ... -
Strength requirements for non-structural components responding nonlinearly under earthquake excitation
Haymes, Kieran; Sullivan, Timothy; Chandramohan, Reagan (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 ...
