Prioritization of seismic retrofit using scoring system
(2020-04-22)As the research and engineering communities advance in their understanding of earthquakes and the associated effects, it becomes apparent that retrofit of old structures is necessary in order to protect the lives and assets ... -
How would changes to serviceability limit state design criteria impact likely repair costs?
(2020-04-22)The earthquake engineering community is currently grappling with the need to improve the post-earthquake reparability of buildings. As part of this, proposals exist to change design criteria for the serviceability limit ... -
Implimenting the NZSEE Seismic Isolation Guidlines: a practioners view over three new designs
(2020-04-22)The draft seismic isolation guidelines provide a significant step forward in promoting a consistent NZ approach to designing and demonstrating compliance in isolated buildings. This paper provides a practitioners’ point ... -
Real world investigation of seismic performance of buildings with hollowcore floors
(2020-04-22)The cyclic test on a super-assembly of hollowcore floor and frames at the University of Canterbury around 2003 revealed the seismic vulnerability of hollowcore floor practice at that time. Subsequent tests were conducted ... -
Wellington's sedimentary basin and its role in amplifying earthquake ground motions: new CBD 3D model and maps
(2020-04-22)During the Mw7.8 Kaikōura earthquake, ground motions in central Wellington were clearly influenced by both the nature of the earthquake source and local amplification effects due to the sedimentary basin. These effects ... -
The seismic performance of structural steel buildings in the 2010/2011 Christchurch Earthquake series and the 2016 Kaikoura earthquake: lessons learned, ongoing research and needs of industry
(2020-04-22)At least 20 earthquakes greater than Ms 7 have taken place in New Zealand since 1850. The recent earthquake that occurred in Kaikoura (Ms 7.8) is considered one of the largest earthquakes since 1855, but Christchurch's ... -
Full-scale shaking table testing of a low-damage steel structure using Resilient Slip Friction Joint
(2020-04-22)The objective of this study is to give an overview of the design and numerical analyses related to a full-scale steel structure shaking table test that includes some structural applications of Resilient Slip Friction Joint ... -
Slip rate variations on major strike-slip faults in central New Zealand and potential impacts on hazard estimation
(2020-04-22)Geological investigations over the last two decades have demonstrated that major strike-slip faults in central New Zealand (e.g., Awatere, Clarence, Wellington faults) have experienced significant millennial-scale variations ... -
Numerical modelling of reinforced concrete walls with minimum vertical reinforcement contents
(2020-04-22)Reinforced concrete (RC) structural walls are effective lateral force-resisting components that are commonly implemented in tall buildings. Recent studies have investigated the impact of minimum vertical reinforcement ... -
A pilot study on effectiveness of flow depth as sole intensity measure of tsunami damage potential
(2020-04-22)Current practices have commonly used tsunami flow depth as the sole hazard Intensity Measure (IM) in fragility functions underpinning tsunami damage, loss and risk assessments. Tsunami flow depth is often obtained from ... -
Cyclic tests of an innovative seismic bracing member - multiple U-shaped flexural plates dissipater
(2020-04-22)Following Canterbury earthquake sequence, there has been an increasing interest in development of low-damage structural design using supplemental damping such as the use of metallic dissipaters. In this research, an ... -
Simplified design procedures for shear piles subject to liquefaction induced lateral spread with evacuation
(2020-04-22)The lateral load transfer between a pile and laterally spreading ground during an earthquake is a complex soil-structure interaction problem given the significant nonlinearity of the stress-strain behaviour of soils during ... -
Predicting yielding of gusset plates in seismic frames using finite element modelling
(2020-04-22)Gusset plates connect lateral bracing to a building by fixing two perpendicular edges into the corners of a frame. This results in a gusset plate having a non-uniform cross-sectional area and generally, each gusset plate ... -
Soil-structure interactions of piled buildings on ground subject to liquefaction and lateral displacements
(2020-04-22)The lateral design of piled foundations for buildings in liquefiable ground is challenging because of potential reduced lateral support and possible lateral ground displacements. Soil-structure interaction (SSI) analysis ... -
Seismic assessment and restraint of non-structural element - practical solutions and implementation challenges
(2020-04-22)Almost 10 years have passed since the 2010 - 2011 Canterbury Earthquake Sequence (CES). These major events, and more recently the 2016 Kaikoura Earthquake have confirmed the poor performance of non-structural elements ... -
Impacts of innovation in performance-based building code
