An automation approach to the seismic assessment and strengthening of unreinforced masonry buildings
(2021-04-14)Large scale seismic assessments in areas of dense unreinforced masonry buildings (URM) is a significant challenge for structural engineers. URM buildings respond to earthquake excitation with a variety of mechanisms as ... -
Design of the Ashburton District Council Civic Centre: A steel designers' learnings from an engineered timber building design
(2021-04-14)This paper discusses the learnings from the structural engineering for the Ashburton District Council (ADC) Civic Centre. The building was initially steel but after consulting with the Ashburton community an alternative ... -
Determining the realistic rotational stiffness of column base connections in steel seismic resisting systems
(2021-04-14)The New Zealand Steel Structures Standard, NZS 3404, provides an upper and lower rotational stiffness boundary for fixed and pinned column base connections for structural analysis, respectively. These boundaries aim to ... -
Development of Dissipative Controlled Rocking Bridge Columns on Monopile Foundations
(2021-04-14)In this research, a low-damage seismic design detail is developed for bridge columns supported on monopile foundations. The low-damage system aims to minimise, and potentially eliminate, the repair time and costs to a ... -
Directing Low-Damage Seismic Design with Building Functionality
(2021-04-14)The upcoming New Zealand Low-Damage Seismic Design (LDSD) guidance information, currently in preparation, is widely anticipated to provide a reference point for aligning low-damage seismic performance targets. A key aspect ... -
Identifying attributes influencing failure mechanisms in unreinforced masonry buildings using machine learning
(2021-04-14)Unreinforced masonry buildings comprise a major part of New Zealand's built heritage and were significantly damaged during the 2010-2011 Canterbury Earthquake sequence. There were 627 URM building assessed in the surveys ... -
Improvements to state school building design including the implementation of low-damage design criteria
(2021-04-14)The Ministry of Education (the Ministry) owns one of the largest property portfolios in New Zealand, with more than 15,000 buildings spread across nearly 2,100 state schools. Following the 2010 Canterbury earthquake sequence, ... -
Investigating CLT Lateral Load Resisting Systems for Taller Timber Buildings
(2021-04-14)Recent taller timber buildings worldwide have often utilized hybrid systems of mixed materials and have been built in regions of low seismicity. Designers often adopt the hybrid material solution of utilizing mass timber ... -
Investigation of vertical reinforcement termination in lightly reinforced concrete walls
(2021-04-14)Reinforced concrete (RC) structural walls are effective lateral force-resisting components commonly implemented in tall buildings. Recent studies have investigated the impact of minimum vertical reinforcement limits on the ... -
Parallel scalability of OpenSees for 2D and 3D ground response analysis problems
(2021-04-14)This study investigates the parallel scalability of the OpenSees finite element analysis platform in the context of 2D and 3D ground response analyses. A series of 2D and 3D models ranging from 7500 to 480000 elements are ... -
Push-over analysis of a 3D architectural wharf structure including soil-structure interaction
(2021-04-14)A new wharf structure was proposed for Te Wānanga in central Auckland. Due to the complex geometry of the proposed wharf, which included plan irregularity, open apertures, deck-suspended planter boxes, suspended nets and ... -
Quantifying the Embodied Carbon Cost from Demolitions Following the Canterbury Earthquakes
(2021-04-14)The 2010/2011 Canterbury Earthquake Sequence resulted in severe financial loss, loss of life and disruption in Christchurch due to liquefaction and damage from strong shaking, which led to the widespread displacement of ... -
Rebuilding Christchurch following the Canterbury earthquakes – implementation of geotechnical lessons learnt
(2021-04-14)Liquefaction during the Canterbury Earthquakes caused significant damage to the built environment of Christchurch and posed a significant challenge to the rebuild effort. This paper describes the process the geotechnical ... -
Risk-Targeted Hazard Spectra for Seismic Design in New Zealand
(2021-04-14)The promotion of risk-targeted hazard spectra as the basis of seismic design internationally has increased over the past decade. Risk-targeted hazard spectra are derived through convolution of hazard curves with representative ... -
Self-drilling dowel connections for ductile link beams in coupled CLT walls
(2021-04-14)Coupled CLT walls with steel link beams can form a more efficient lateral load resisting system for tall timber buildings when compared to single CLT shear walls. To achieve adequate coupling between CLT walls and ensure ... -
The top enablers and barriers of seismic technology adoption in construction
(2021-04-14)The slow process of adoption of the new technologies has been identified as a significant issue in the construction industry. In order to address this issue, the top enablers and barriers of the adoption process are needed ... -
Validation of NZ small-magnitude ground-motion simulations using complex structural systems
(2021-04-14)This study assesses the need to consider complex structural models in ground-motion simulation validation. It develops a novel statistical framework to quantify the proportion of the differences in structural responses ... -
Wall-to-floor connection behavior in a low-damage concrete wall building
(2021-04-14)Following the 2010/2011 Canterbury earthquakes, approximately 60% of multi-story buildings with reinforced concrete walls required demolition. Both practitioners and researchers have increasingly realized that low-damage ...
