Influence of ground motion orientation on predicted seismic compression
(2020-04-22)Seismic compression is the accrual of contractive volumetric strain in unsaturated or partially saturated sandy soils during earthquake shaking and has caused significant distress to overlying and nearby structures. The ... -
Introducing a low damage system incorporating rocking braced frame and resilient slip friction joint as a shear key
(2020-04-22)In this paper, to achieve a self-centring damage avoidance rocking framed system, RSFJ has been employed as a shear link between braced frame and its boundary columns. Such a system could be used for a single or coupled ... -
Mitigation of liquefaction induced lateral spread using jet grout shear walls
(2020-04-22)The load transfer mechanism between ground subject to liquefaction induced lateral spreading and jet grout shear walls is complex. The shear walls comprise rows of jet grout columns, constructed in a primary-secondary ... -
Modelling of vertical control in magnetic levitation for building isolation during earthquakes
(2020-04-22)Earthquakes cause significant damage to buildings due to strong vibration of the ground. Levitating houses using magnets and electromagnets would provide a complete isolation of ground motion for protecting buildings from ... -
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 ... -
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 ... -
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 ... -
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 ... -
Review of recently constructed buildings that combine steel frames and concrete walls
(2020-04-22)Recent building construction in New Zealand has exhibited an increase in the use of structural steel due to its availability and perception of good seismic performance. Despite the renewed popularity of structural steel ... -
Robustness and accuracy of model-free structural health monitoring
(2020-04-22)Rapid, accurate structural health monitoring (SHM) assesses damage to optimise decision-making. Many SHM methods are designed to track nonlinear stiffness changes as damage. However, highly nonlinear pinched hysteretic ... -
Scion Hub: A three storey seismically resilient timber diagrid
(2020-04-22)The new three storey Hub building at Scion’s campus in Rotorua is an innovative approach to providing seismic resilience in timber. A demonstration project for Scion’s work in the timber industry it utilises several forms ... -
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 ... -
Seismic base isolation of high-rise RC shear wall building using lead core rubber bearings
(2020-04-22)The use of base isolation technique is an effective way to control the seismic demands in buildings. The RC shear wall buildings represent the typical high-rise construction in several parts of the world. The seismic story ... -
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)
