1170.5 Reimagined: from a structural designers view
(2021-04-14)Our loadings code has adapted and extended to incorporate new knowledge as it has emerged over the last 50+ years: could a re-write encourage engineers to design better buildings? This paper outlines some intentionally ... -
A bespoke analytical methodology for seismic safety assessment of spillway gates: case study of Waipapa dam spillway on the Waikato River
(2022-04-27)This paper presents a seismic assessment methodology tailor-made for the Waipapa Dam Spillway gates on the Waikato River which were found to have potential dam safety issues under the 1 in 2500-year annual exceedance ... -
A comparison of New Zealand seismic code requirements with other major design codes in the implementation of seismic resilient devices
(2021-04-14)In the ever-evolving earthquake engineering field, the need of the hour is to achieve earthquake-resistant buildings which have immediate occupancy following an earthquake. This implies that the demand for resilient dampers ... -
A preliminary investigation of validity of conventional single-mode pushover analysis in multi-mode systems
(2022-04-27)Pushover analysis is a simplified inelastic analysis approach where a structure is subjected to increasing increments of monotonic imposed force or displacements to estimate the inelastic deformations in the structural ... -
Adequacy and Retro-Fitting of Timber Frame House Foundations on Slopes
(2021-04-14)Previous studies have indicated that there are significant issues with the structural strength and stability of many existing house foundations on sloping sites. This was confirmed after the Christchurch earthquakes, where ... -
Advances in Floor Diaphragm In-Plane Modelling Using Truss Elements
(2021-04-14)Different methods to model building floor diaphragm in-plane stiffness with truss elements are compared to identify the method most suitable for analysis in design. The methods considered include (i) Elastic truss, (ii) ... -
An attempt to determine a relationship between a mass-spring-friction damper single-degree-of-freedom system’s equivalent viscous damping ratio and its corresponding friction coefficient
(2021-04-14)Damping forces are always present in real structures, occurring in several different forms, making them challenging to model expressly. Damping is often assumed to be viscous in nature, due to the simplicity of the ... -
Application of resilient rocking cores in low damage mass timber structures: A case study
(2022-04-27)The application of mass timber structures made with massive wooden panels such as Cross Laminated Timber (CLT) has significantly increased in the last few years owing to their many architectural and structural advantages, ... -
Assessing the impact of acceleration-sensitive components on the seismic losses of multi-storey office buildings
(2022-04-27)The Ministry of Building, Innovation and Employment is developing advice on how to deliver Low Damage Seismic Design (LDSD) protection for buildings through their Tū Kahika: Building Resilience platform. A preliminary ... -
ATC-145: Influence of prior shaking on earthquake response and repair requirements for structures and elements
(2021-04-14)ATC-145 is a FEMA funded project aimed at developing a Guide for repair of earthquake damaged buildings to achieve future resilience. Thanks in part to EQC funding, the project includes substantial New Zealand representation. To ... -
Balancing seismic resilience and lean design to reduce the embodied carbon of buildings
(2021-04-14)The building and construction sector needs to make big changes to reduce greenhouse gas emissions if New Zealand is going to meet the legally binding targets of the 2019 Zero Carbon Act, and its commitments under the Paris ... -
Blenheim gravel liquefaction assessment using the Chinese dynamic cone penetration test
(2021-04-14)Worldwide, one of the issues that has been constantly brought to attention by engineers is the lack of guidance for geotechnical characterization and liquefaction assessment of gravelly soils. In gravelly soils, the ... -
Case studies on low damage mass timber structures with resilient connections
(2021-04-14)There is increasing public pressure to have seismic-resistant structures made with massive wooden panels such as Cross Laminated Timber (CLT). It is well-known that the type and behaviour of the connections govern the ... -
Code requirements for column confinement with a view on drift
(2022-04-27)Confinement provided by transverse reinforcement plays an essential role in reinforced concrete columns. When proportioned judiciously, confinement provides longitudinal bar restraint, contributes to shear resistance, and ... -
Cyclic behaviour of hold-downs using mixed angle self-tapping screws in Douglas-fir CLT
(2021-04-14)Long self-tapping screws are now commonly used in mass timber construction in New Zealand and globally due to their high strength and ease of installation on site. Under axial loads, self-tapping screws are strong and stiff ... -
Developing LSN-based pipe repair rate functions utilising data from the 2011 Canterbury earthquakes
(2021-04-14)The Canterbury Earthquake Sequence adversely impacted built, economic and social environments. This included widespread physical damage to the water supply pipe network in Christchurch, resulting in long service disruptions. ... -
Drift Demand Estimates for Inelastic Torsional Response of Half-scale Seven-storey RC Specimens
(2021-04-14)Existing reinforced concrete buildings with irregularities are susceptible to torsional response and resulting localised damage or collapse under seismic excitation. Primary source of torsional response can be inherent ... -
Ductility factor validation for CLT walls with bolted hold-downs: preliminary analysis and observations
(2022-04-27)High-capacity cantilever CLT walls can be created with bolted hold-downs to resist earthquake loading. This study briefly presents the experimental results and cyclic behaviour of the representative test specimen. Then ... -
Earthquake Design Loads on Retaining Walls
(2022-04-27)Free-standing retaining walls are usually designed for earthquake loads using the Monobe-Okabe method and assuming cohesionless soil backfill. This simple design approach has led to satisfactory performance and is supported ... -
Elastic Design (μ=1.0) of Damage Avoidance Structures
