Building collapse due to P-delta – what is the risk?
(2024-04-09)Second-order P-delta effects require consideration as part of the seismic design and assessment of buildings, as they can amplify lateral displacement demands and potentially cause collapse through dynamic instability. ... -
Improving the Post-Earthquake Response of Hospitals: The Implementation of Priority Response Agreements
(2024-04-09)It is vital that decisions on which hospital buildings can continue to be used following damaging earthquakes are made quickly. A key component of the decision-making process is timely input from experienced engineers ... -
Applicability of existing CPT-Vs correlations to direct-push crosshole and cone penetration test data for shallow Holocene-aged New Zealand soil deposits
(2024-04-09)A number of empirical correlations have been proposed to estimate shear wave velocity (Vs) using cone penetration test (CPT) data as a result of the growing availability of global databases. The performance of four existing ... -
An energy dissipation and seismic reduction design of a hospital inpatient building using viscous fluid dampers
(2024-04-09)Viscous fluid damper is commonly used in China to reduce building seismic response. This paper introduces the design methodology and key-points of viscous fluid damper in China using an energy dissipation design of an ... -
Improving Post-Earthquake Emergency Management of Heritage Buildings
(2024-04-09)The emergency response is one of the most thorny and challenging activities for the local and national authorities. It is necessary to act quickly and in an effective manner - any delay or misstep could cost lives and ... -
Multi-scenario approach for the assessment of liquefaction exposure and impact across New Zealand State Highways
(2024-04-09)Events such as the 2010-2011 Canterbury Earthquake Sequence or the 2016 Kaikōura earthquake demonstrated the impacts of liquefaction and lateral spreading across New Zealand infrastructure networks. Statistical liquefaction ... -
Earthquake Protection Technologies for Structural and Non-Structural Applications: Case Studies Worldwide
(2024-04-09)Seismic hazards pose significant risks to the built environment, demanding effective mitigation measures. In recent years, there has been a surge in seismic control technology development, highlighting its crucial role in ... -
Tsunami resilience: Aotearoa New Zealand's path to integrated risk management and engineering design
(2024-04-09)Tsunami threats persist along coastlines worldwide, necessitating proactive measures to safeguard lives and property. Recent catastrophic events, such as the 2004 Indian Ocean tsunami and the 2011 Japan tsunami, have ... -
Finite Element Modelling (FEM) of the Asymmetric Friction Connection (AFC) with Belleville Springs (BeSs): challenges and ongoing developments
(2024-04-09)The Sliding Hinge Joint (SHJ) is a low-damage beam-column connection used in steel moment-resisting frames. It allows large beam-column rotation to occur with minimal damage, through sliding in asymmetric friction connections ... -
Non-contact Structural Damage Detection by Natural Frequency Measurement using Microphone
(2024-04-09)Structural Damage Detection methods are crucial for infrastructure maintenance. The general principle involves the identification of changes in natural frequencies induced by stiffness reductions. This paper introduces an ... -
Application of Low Damage Tension Braces in Top Extensions of Existing Buildings: A Case Study for Seismic Upgrade
(2024-04-09)Tension-only braces are generally used as diagonal cross members (rods, flat bars or similar) to resist lateral loads. The application of these braces has been limited to low-rise buildings (generally up to two stories) ... -
Out-of-plane capacity of low-damage partition wall systems: the balance between maintaining robustness and allowing relative movement
(2024-04-09)The need for low-damage non-structural systems has been apparent following many major earthquakes, where significant damage has commonly been observed to the non-structural contents of buildings. Damage to non-structural ... -
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 ... -
