Seismic damage avoidance design of moment resisting frames with innovative resilient connection
(2020-04-22)Moment-resisting frames are one of the efficient lateral-load resisting systems in terms of providing architectural freedom in design and imposing smaller forces on foundations. Recent major earthquakes have resulted in ... -
Seismic response of half-scale seven-storey RC systems with torsional irregularities: blind prediction
(2020-04-22)Past earthquakes have highlighted vulnerabilities to damage or collapse of building structures due to torsional response. While methodologies to capture torsional demand due to strength and stiffness irregularities have ... -
Seismic retrofitting of RC-frames using Resilient Slip Friction Joint toggle-bracing system
(2020-04-22)Seismic retrofitting of the current non-ductile or limited ductile RC buildings is one of the challenging design topics among the scholars and engineers. The common technique for RC-frame retrofitting involves adding ... -
Self-centring bracing system: avoidance of elastic buckling for braces with one intermediate damper
(2020-04-22)Today, more attention is being given to timber material by practitioners as a structural member owing to benefits that this material can offer such as high strength to weight ratio, being environmentally friendly and ... -
Shear Wall Design Tool - Structural Engineering Design Society NZ (SESOC)
(2020-04-22)SESOC has, over a period of time, developed and acquired a number of structural software design programs. This paper will preview a new development, namely “Gen-Wall”, a software program developed specifically for the ... -
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 ... -
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 ... -
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 ... -
Source modelling considerations for ground motion simulation validation of moderate magnitude active shallow crustal earthquakes in New Zealand
(2020-04-22)This paper summarises progress toward NZ-wide physics-based hybrid broadband ground motion simulation validation of moderate magnitude (5.0 < Mw < 7.0), active shallow crustal earthquake events through low spatial resolution ... -
Structural engineering observations from the 26 November 2019 M6.4 Albanian earthquake
(2020-04-22)The Mw 6.4 earthquake that occurred near the city of Durres, located on the west coast of Albania, may be considered small in comparison to the design earthquake, yet it caused an enormous amount of damage to buildings. ... -
The New Zealand Building Code - a rethink?
(2020-04-22)Are the regulatory settings for structural and geotechnical design of structures in New Zealand currently appropriate? It is contended that they are not. New Zealand led the world in performance based building regulation ... -
The Scott Base Redevelopment: design response to natural hazards
(2020-04-22)The Antarctic environment is extreme, making consideration of resilience crucial for survival. This paper outlines how site-specific hazards are being considered within a resilient design framework for the Scott Base ... -
The Scott Base redevelopment: Ross Sea geological hazards
(2020-04-22)To inform Scott Base development planning, we discuss the effects of historical earthquakes, tsunamis and volcanism on Antarctica and then focus on assessing the potential hazard from future tsunamis in the Ross Sea region. ... -
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 ... -
Towards a better understanding of the development of the strength in Asymmetrical Friction Connections (AFCs)
(2020-04-22)In the current design practice, the strength of Asymmetric Friction Connections (AFCs) is calculated considering the friction force developed at both sliding interfaces using the bolt tension reduced by the moment – shear ... -
Unbonded post-tensioning of face loaded URM cavity walls under semi-cyclic and dynamic loading
(2020-04-22)An unbonded post-tensioning (PT) system installed into full-scale face loaded (out-of-plane) URM cavity walls using threaded rod and steel anchor plates spanning the cavity was investigated through experimental testing. ... -
Wāhine tapuhi ō te parawhenua mea kia mataara- Wāhine-led, community-based research on earthquake resilience
(2020-04-22)Despite increasing attention on the importance of earthquake risk reduction for Aotearoa New Zealand communities, there are limited Māori-medium resources available, and more representation of Māori wāhine (women) researchers ... -
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 ...
