Seismic Resurrection of 13-storey Apartment Building at 66 Oxford Terrace, Christchurch
(2024-04-09)This precast concrete apartment building at 66 Oxford Terrace was completed in 2005 and has considerable architectural merit. The Engineers employed by the Body Corporate post the CES of 2010 / 2011 discovered that the ... -
A Case for Resilience in New Zealand
(2024-04-09)The concepts of resilience and holistic building performance drive the seismic design approach for structures with national significance or special post-disaster functions. Although considerable advancements have been made ... -
Multistage Friction Connection Optimisation
(2024-04-09)This paper describes the use of multi-stage friction connections (MFCs) to modify hysteresis curve characteristics of structures in order to decrease their peak and residual displacements. Both cases with and without P-delta ... -
Holistic Considerations for Low-Rise Building Design
(2024-04-09)Two low-rise residential structures, a single-storey residential structure (SSRS) and one triple-storey structure (TSS), are initially described using building information modelling (BIM) software. The structures are then ... -
Practical issues in time-history analysis of low-rise concrete wall buildings with subterranean levels
(2024-04-09)In New Zealand, older power stations are commonly low-rise concrete wall structures with rigid basements housing generators, turbines and other electro-mechanical infrastructure at or below ground level. These structures ... -
Shake-table test of flexural RC beams subjected to different levels of repair
(2024-04-09)Typically, damaged reinforced concrete (RC) building components are fully repaired to achieve the highest performance recovery. However, this repair objective may not necessarily be essential to achieve building performance ... -
Coordinating for Success - Enhancing Seismic Restraint Through Early Design Involvement
(2024-04-09)Tuhiraki is a new agricultural science facility for AgResearch Ltd., situated in Lincoln, Canterbury. The workplace and laboratory structures witnessed significant improvements in design efficiency and coordination of ... -
Experimental and Analytical Study of Fillet Welds for Seismic Actions
(2024-04-09)New Zealand steel standards NZS3404 uses a simplified method to predict the weld design capacity and to size the weld. According to the industry feedback on the design and manufacturing of the seismic welded connections, ... -
Seismic resilient structures using pre-cast pre-stressed concrete panels for modular construction
(2024-04-09)Earthquake resiliency combined with sustainability can be achieved through state of the art technology and construction methods. In this paper, a new construction methodology is proposed for resilient and sustainable ... -
Earthquake scaling relations, and testing and evaluation of the New Zealand National Seismic Hazard Model 2022.
(2024-04-09)We summarise two projects that contributed to the development of the New Zealand National Seismic Hazard Model 2022 (NZ NSHM 2022). First, we summarise the development of new magnitude-source area scaling relations for ... -
Analysis of Felt Detailed ‘Final Comments’ for the 2016 Kaikōura earthquake
(2024-04-09)The GeoNet “Felt Detailed” survey collects information about people’s experiences after earthquakes - from behavioural responses through to damage to buildings and infrastructure. One of the questions asked at the end of ... -
Comparison between weld sizing methods included in steel structure standards
(2024-04-09)Although the weld sizing methods given in standards look simple, the actual stress distribution in most welds is complex. Some simplifications are assumed to make designing welds easier for design engineers in different ... -
Seismic response of sustainable, resilient eccentrically braced frames
(2024-04-09)“Circular design” and “Construction 4.0” are two distinct concepts that can be complementary and beneficial within the construction industry while prioritising sustainability. Nascent global Construction 4.0 knowledge ... -
