Investigating the effect of stiffness on the seismic performance of RC structures
(2023-04-19)This study investigates the correlation between stiffness and the seismic performance of RC structures. Structural performance was compared for buildings affected by four different earthquakes, Tokachi-Oki (1968), Chile ... -
Source of numerical non-convergence in the analysis of bilinear SDOF systems
(2023-04-19)Numerical non-convergence is an important factor impeding the research into and widespread adoption of the nonlinear dynamic analysis. Upon encountering non-convergence at an analysis time step when using an implicit time ... -
How to assemble elemental damping?
(2023-04-19)An elemental damping model has recently been proposed as an alternative to the Rayleigh damping model to avoid spurious damping forces during inelastic seismic response. It has shown great potential because it has the ... -
Site-specific seismic hazard analysis - evolving developments in practice
(2023-04-19)Site-specific hazard analyses (SSHAs) are undertaken to inform seismic actions for the design of important projects in New Zealand. These have typically adopted the 2010 National Seismic Hazard Model (NSHM) as the reference ... -
International alignment and update of the New Zealand earthquake intensity scale
(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 ... -
GeoNet’s Shaking Layer Tool: Generation of near-real time ground shaking for post-event response
(2023-04-19)Information on ground shaking following an earthquake is important for many applications from emergency response, engineering assessments, infrastructure management, insurance claim estimation and research. GeoNet, along ... -
Base isolated building preformance and the impact of the national seismic hazard model
(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 ... -
Method for the explicit consideration of ground motion duration in NZS 1170.5
(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 ... -
Behaviour of Unreinforced R.C. Beam-Column Joints Under Bidirectional Loading
(2023-04-19)Modern building codes for reinforced concrete (RC) frame structures in areas susceptible to earthquakes prescribe detailing requirements for the beam-column joint to prevent shear failure and subsequent loss of gravity ... -
Trends in systematic site residuals with geomorphic categories for New Zealand ground-motion instrument sites
(2023-04-19)This study investigates systematic site-effects from prediction residuals of physics-based ground-motion simulations for a database of small magnitude (i.e., 3.5 ≤ MW ≤ 5) shallow crustal earthquakes in New Zealand. The ... -
Dynamic analysis of tall reinforced concrete walls designed with minimum vertical reinforcement
(2023-04-19)Analysis of tall walls subjected to the earthquake ground motions highlights the amplified dynamic moment response at the mid-height due to the higher mode effect. The amplified moment demand may result in unexpected ... -
Estimates of site periods from mHVSR analysis of IRIS temporary seismograph networks
(2023-04-19)The effects of soil stratigraphy and sedimentary basins on earthquake ground shaking are well-established. These effects can be represented using a range of site metrics, with the focus of this paper being the fundamental ... -
Seismic Behaviour of Slender Rectangular Reinforced Concrete Walls based on analytical methods
(2023-04-19)In the seismic design and assessment of structures, one of the key parameters is the displacement capacity of the structural elements. Slender reinforced concrete (RC) structural walls are one of the more commonly used ... -
Testing of heavily damaged reinforced concrete walls repaired using concrete and steel replacement
(2023-04-19)Post-earthquake damage assessments are essential to decisions on the need for and extent of structural repairs. Despite this, New Zealand currently has no official guidelines to evaluate the residual capacity of ... -
Experimental study on structural performance and damage characteristics of repaired flexural RC members
(2023-04-19)Understanding the expected seismic performance recovery of repaired members is important to make an effective recovery plan for damaged buildings. In this research, three RC beam and three RC wall specimens were subjected ... -
Post-disaster building functionality: preliminary findings of a systematic review
(2023-04-19)During a natural hazard event, buildings are likely to experience some sort of damage, thus limiting their ability to function as intended. The severity of the ensuing consequences for various stakeholders and the community ... -
Seismic Performance Comparison of New Zealand and Japanese Concrete Moment Frames
(2023-04-19)Observations of the performance of reinforced concrete (RC) buildings after the 2016 Kumamoto earthquake in Japan showed buildings designed using Japanese standards resulted in less damage and downtime compared to buildings ... -
Wellington Children’s Hospital - a different approach to a seismic restraint project
(2023-04-19)The seismic restraint design for non-structural elements in the new, Importance Level 3, Wellington Childrens Hospital building utilised a considered and efficient design approach that minimise the number of seismic ... -
Lincoln University Waimarie building: An application of friction damping devices with recentring for low damage design
(2023-04-19)The experience from Christchurch and Kaikoura seismic events demonstrated well that the ‘life safety’ criteria is not sufficient to protect the community from earthquake impact. Currently, the community expects more measures ... -
Understanding and Improving the Seismic Resilience of Hospital Buildings
(2023-04-19)The establishment of Te Whatu Ora – Health New Zealand has enabled more direct national oversight of public hospital buildings across New Zealand. This has also led to the need for a more comprehensive understanding of ...
