Proposal of repair index and strategy for recovery of reinforced concrete buildings damaged by earthquakes
(2024-04-09)Restoration of damaged buildings is an important issue for achieving smooth recovery of society after a devastating earthquake disaster. In general, in past earthquake disasters in Japan, demolition or repair judgement was ... -
Prediction of crack widths in NZS 3101 and its significance in the seismic design of connections
(2024-04-09)Cracking of reinforced concrete structures due to bending or tension has usually great significance on structural behaviour. Design codes limit crack widths for durability and aesthetic purposes. The research of cracking ... -
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 ... -
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. ... -
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 ... -
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 ... -
Effect of Strengthening Techniques Applied to RC Walls with Post-installed Openings on Shear Resistance
(2024-04-09)Shear walls increase stiffness and strength of reinforced concrete frame buildings improving their capacity to resist earthquake damage. Nevertheless, it is common for shear walls to contain openings for a variety of ... -
Towards 3D ground motion simulation-based site amplification: a Wellington case study considering multiple basin geometries
(2024-04-09)This paper presents a study on 3D ground motion simulation-based site amplification using the Wellington region of New Zealand as a case study. Several recent models of the Wellington sedimentary basin have been developed ... -
Geotechnical design of a secant piled underground pump station in liquefiable ground
(2024-04-09)The geotechnical design of underground structures with a high importance level, in a dense urban area, in liquefiable ground, and adjacent to existing structures that are sensitive to settlement is challenging because ... -
Soil structure interaction in laterally displacing ground
(2024-04-09)Design or assessment of structures founded on ground with a potential for seismic induced ground displacements requires careful consideration of the associated soil structure interaction (SSI). These seismic ground ... -
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 ... -
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 ... -
Evaluating the benefits of rocking shallow foundations
(2024-04-09)Rocking foundations can offer significant benefits both in terms of seismic performance and reduced embodied carbon. This paper applies a displacement-based design procedure to achieve a rocking foundation for a multi-storey ... -
Turnbull Library: Strengthening for Heritage and Resilience
(2024-04-09)Turnbull House is a Category 1 Heritage building on Bowen Street in Wellington. It was built in the 1910s as a residence and library, primarily from unreinforced masonry. Although some strengthening was carried out in the ... -
Performance of RC buildings in the 2023 Turkey-Syria earthquakes
(2024-04-09)The 2023 Mw 7.7-7.8 Turkey-Syria earthquakes were devastating events that resulted in widespread damage throughout several regions of western Turkey. In March 2023, the Architectural Institute of Japan deployed a team of ... -
Challenges associated with geotechnical design of Te Kaha – Canterbury’s Multi-Use Arena
(2024-04-09)Te Kaha is a new 36,000-seat permanently covered multi-use arena in Christchurch and is the final anchor project in the Christchurch Central Recovery Plan, following the Canterbury earthquake sequence of 2010-2011. The ... -
Nationwide investigation of systematic site effects in New Zealand: Residual analysis of physics-based ground motion simulations
(2024-04-09)This study examines systematic site effects from the prediction residuals of physics-based ground motion simulations using a dataset of small magnitude (3.5 ≤ Mw ≤ 5.0) active shallow crustal earthquakes recorded in New ... -
Damage Level Prediction of RC Building for Future Earthquakes Based on Seismic Response Observation
