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
(2024-04-09)This research introduces a novel three-dimensional seismic isolator designed to evaluate the coupled horizontal-vertical responses of a five-story building. A comprehensive structural analysis using the OpenSees software ... -
The use of 3D LE methods to calculate slope stability during strong earthquake shaking
(2024-04-09)This paper discusses the application of three-dimensional (3D) limit equilibrium (LE) analysis for slope stability, with a focus on seismic considerations. While traditional 2D limit equilibrium analyses have been extensively ... -
Indicators for quantifying post-disaster functionality: a neighbourhood scale
(2024-04-09)Natural disasters, such as earthquakes and cyclones, affect people physically and mentally. They can be destructive to the built environment, hindering infrastructure, lifelines, buildings and homes, which all support the ... -
Moment Curvature Analysis of wide-flange steel columns with local buckling dominant mode of failure
(2024-04-09)One of the key information that can provide an insight into the seismic behaviour of structural elements is their force-displacement curve. Such a curve can be obtained based on a moment-curvature analysis and using an ... -
Recommended practice for seismic restraint design of suspended ceilings
(2024-04-09)Seismic restraint of suspended ceilings in the New Zealand environment has seen significant evolution over the past decade. Amendments to NZS1170.5 and updates to AS/NZS2785 are intended to drive better earthquake resilience ... -
Assessing the Impact of Drilling Techniques on the Tensile Strength of Mechanical Screw Anchors in Masonry
(2024-04-09)Mechanical screw anchors are used for a range of structural connections on masonry buildings, including as part of earthquake retrofit solutions. While extensive research has been devoted to understanding the working ... -
Urban Geophysics and Seismic Hazard Assessment in the Wellington CBD
(2024-04-09)Many of our cities are built on sedimentary basins. Both the depth and shape of the basin will influence, and generally enhance the level of shaking. Our focus is the Wellington CBD, where we use seismic reflection and ... -
Innovative design methodology for secant pile walls
(2024-04-09)Many infrastructure projects in New Zealand require deep excavations in unstable granular, soft or liquefiable soil below the water table. The use of secant piles to form temporary or permanent retaining walls supporting ... -
Shake-Table Testing of the Resilient Slip Friction Joints
(2024-04-09)A consortium of university researchers (UoA, AUT and UC) from New Zealand and Tongji University have undertaken shake-table tests of various friction damping devices. This testing program is under the banner of the ROBUST ... -
Seismic response of frames with building cladding elements
(2024-04-09)This paper presents the concept, methodology and findings of the analysis of frames with building cladding elements exposed to seismic events. Inelastic nonlinear push-pull analyses, and hand analyses, are conducted to ... -
SESOC Retaining Wall Design Guide - Methodology and Validation
(2024-04-09)Some years in development, the SESOC Cantilever Timber Pole Retaining Wall Design Guide has been prepared in response to the need for a comprehensive, coherent design basis, albeit for low rise, cantilever, walls. Though ... -
