Comparing alternative methods to account for shallow site effects in hybrid broadband ground-motion simulations
(2024-04-09)Shallow site effects are usually not explicitly modelled in hybrid broadband ground-motion simulations, and their proper incorporation may be key to improving prediction at soil sites. This paper examines five methods to ... -
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 ... -
Low-Rise Buildings Guideline – Stage 1 Review
(2024-04-09)The seismic assessment of low-rise buildings is an important area of seismic assessment in New Zealand given the prevalence of these types of structures, especially outside the main centres. The Joint Committee for the ... -
Quantification of economic benefits of functional recovery-based design: a stepwise review of the methodology
(2024-04-09)Recent earthquake experiences have shown that although life-safety objectives have been met, current seismic design standards were unable to ensure an acceptable level of robustness and recovery timeframe for all modern ... -
Bridging engineering and social perspectives of post-earthquake functional recovery of commercial buildings
(2024-04-09)The emerging post-earthquake functional recovery concept is gaining momentum among building professionals and policymakers. It highlights the importance of incorporating recovery-oriented objectives into building codes, ... -
Seismic Ratcheting Considerations
(2024-04-09)This paper describes recent research conducted to understand the effects of structural characteristics on the seismic response of single storey structures with a ratcheting tendency. The ratcheting tendency was characterised ... -
Informing Clients on the Business Case for Seismic Resiliency
(2024-04-09)The role of structural engineer has been to ensure life safety of building occupants during a seismic event. In the past, a singular focus on this performance target has resulted in structures that relied on the dissipation ... -
The role of risk perception, risk communication, and comparative risk principles in resilience building
(2024-04-09)Increasing resilience to earthquakes through choices such as building design requires people to understand, evaluate, and act on risk. Therefore, any communication efforts, either formal or informal, which are aimed at ... -
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 ... -
