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 ... -
Geotechnical design for severe liquefiable ground improvement with SCRR technique: Waikato case study
(2024-04-09)This paper introduces an innovative earthquake geotechnical design approach for severe liquefiable ground, adopting ground improvement using the patented Subsurface Compacted Rubble Raft (SCRR) technology in a Waikato ... -
Investigating the interaction between rocking amplitude and ground motion characteristics via artificial neural networks
(2024-04-09)Unreinforced masonry structures are particularly vulnerable to out-of-plane seismic loading. During an earthquake, masonry walls behave as rigid bodies undergoing rocking motion. Thus, from a dynamics perspective, their ... -
Damage Level Prediction of RC Building for Future Earthquakes Based on Seismic Response Observation
(2024-04-09)This paper proposes a method of damage evaluation of reinforced concrete buildings based on seismic response observed by sensors, and prediction of expected response by future earthquakes. Real performance curve and damping ... -
Estimation of electricity supply restoration time with interdependencies under cascading hazard risk approach
(2024-04-09)The electricity infrastructure network functions as a system with several components interconnected and distributed over a region. When subjected to earthquake and its related cascading hazards, the vulnerable components ... -
Omāroro Reservoir: A Case Study. It’s Cheaper to Work with Nature
(2024-04-09)By all accounts, Wellington, New Zealand is a challenging seismic environment for the design and construction of infrastructure. In recent years, this challenge has increased with our deeper understanding of Aotearoa’s ... -
Implications for Design of Parts and Components from Updates to New Zealand Seismic Loading Standard and National Seismic Hazard Model
(2024-04-09)New Zealand engineering practitioners will see revisions to the seismic loading standards for non-structural elements (parts and components) in the draft technical specification TS1170.5. This paper considers the implications ... -
A Review on Nonlinear Time History Analysis of Structures
(2024-04-09)Nonlinear time history analysis (NTHA) is a powerful approach for assessing the seismic response of buildings, enabling engineers to better understand and predict the structural behavior under dynamic loading. This review ... -
NZ Industry Nonlinear Response History Guidelines
(2024-04-09)Nonlinear response history analysis (NLRHA) provisions in NZS 1170.5 were developed 20 years ago. Significant developments in the selection and scaling of ground motion records have occurred since this standard was ... -
Impacts of ground motion and scaling method selection on the performance of rocking wall systems with friction connections
(2024-04-09)Dynamic time-history analysis has long been regarded as an acceptable and reliable method for seismic design of structures not covered by codal guidelines and often referred to as "alternative" design. Resilient rocking ... -
From Research to Practice: Case Study on Mixed Angle Screws Hold Down Connections for a 6-Storey CLT Shear Wall Building
(2024-04-09)Mass timber structures are a growing topic in the New Zealand design environment. To design mass timber buildings to the moderate or high seismic demands of much of New Zealand, strong stiff, and ductile seismic systems ... -
QA/QC methods for grouted Drossbach duct connections in precast concrete shear wall panels – case study: new 12-storey building in Auckland
(2024-04-09)This paper explores the issues and limitations of grouted Drossbach duct connections, and investigates the quality assurance/control (QA/QC) methods used in the construction monitoring of a new 12-storey hotel in Auckland. ... -
Liquefaction-Induced Parabolic Subsidence Method for analysis of shallow foundations
(2024-04-09)In New Zealand, the document “Repairing and Rebuilding Houses Affected by the Canterbury Earthquakes" issued by the MBIE, has been widely embraced by consulting engineers and local authorities as a reference for building ... -
Post-Earthquake Response: Update on the Improvements to the Rapid Building Assessment Process and Building Management In Emergencies
(2024-04-09)It is vital that New Zealand has both the systems in place and trained personnel ready to respond to earthquakes and other natural disasters. Rapidly assessing the usability of affected buildings and identifying an ... -
Enhancing Structural Resilience: Three-Dimensional Seismic Isolation (3DSI) in Practice
