Resin Injection ground improvement for liquefaction mitigation at Poverty Bay Rugby Club, Gisborne
(2024-04-09)Gisborne is located near the Hikurangi Subduction Zone which contributes to a significant amount of the seismic activity in New Zealand. This coupled with Gisborne’s soil profile consisting of liquefiable sands has resulted ... -
Rapid Earthquake Rupture Characterisation for New Zealand Using the FinDer Algorithm
(2024-04-09)For large and damaging earthquakes, rupture location and extent are critical inputs for impact forecasts and response decision-making. This information has the potential to significantly improve estimates of ground shaking, ... -
Pres-Lam: An innovative and collaborative timber solution
(2024-04-09)The pressing need for resilient structures in earthquake-prone regions has led to the development of innovative seismic solutions. Among them, PRESSS and Preslam stand out as a groundbreaking approach. This paper offers ... -
Machine Learning Correction of Overpredicted Liquefaction Manifestation using Liquefaction Severity Number
(2024-04-09)Many of state-of-practice methods for predicting liquefaction manifestation, such as the Liquefaction Severity Number (LSN) of van Ballegooy et al. (2014) are known to suffer from significant overprediction in regions ... -
Code Based Design vs. Performance Based Design
(2024-04-09)Modern day design codes are the result of six decades of seismic engineering developments most of which have been focused on elastic modal methods. Modal methods are strictly not applicable to inelastic systems and hence ... -
P-delta or P-theta analysis?
(2024-04-09)Engineers have methods to estimating the displacements of inelastically responding structures in earthquakes. Rules to estimate such displacements for a structure with a certain period, damping, and hysteretic behaviour ... -
Impact of base conditions on the bracing performance of LTF walls
(2024-04-09)Residential buildings in NZ are often low-rise light timber-framed (LTF) buildings where LTF walls provide the gravity and lateral load resisting systems. LTF building construction largely follows the prescriptive standard ... -
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 ... -
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 ... -
