Developing guidelines for the seismic assessment of glazing systems
(New Zealand Society for Earthquake Engineering, 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
(New Zealand Society for Earthquake Engineering, 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 ...
A simple method to predict floor response spectral demands on nonstructural components
(New Zealand Society for Earthquake Engineering, 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 ...
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 ...
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 ...
Investigation of the Plastic Drift Capacity of RC Frames with Beam-Column Joint Failure
(New Zealand Society for Earthquake Engineering, 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 ...
Finite Element Analyses of Hollow Core Units Subjected to Shear and Torsion
(New Zealand Society for Earthquake Engineering, 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 ...
Seismic Design and Analysis of a Medium Density Residential Building
(New Zealand Society for Earthquake Engineering, 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 ...
Investigating the impact of design criteria on the expected seismic losses of an office building
(New Zealand Society for Earthquake Engineering, 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 ...
Experimental loading protocols to evaluate the seismic performance of floor systems
(New Zealand Society for Earthquake Engineering, 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 ...
