A quantitative risk assessment of seismic slope stability for a tailings dam
(2023-04-19)Tailings are a by-product of mining, consisting of silts and sands from the processed rock or soils and susceptible to liquefaction under earthquakes. Tailings Storage Facilities (TSFs) include dams that are designed and ... -
A risk-based framework to account for step-change behaviour in seismic assessment
(2024-04-09)In New Zealand, the seismic assessment of existing buildings focuses on life safety risk. The assessed capacity of a building is limited by the capacity corresponding to any vulnerability (or weakness) that can potentially ... -
A Sensitivity Study of the Design Parameters Affecting the Global Stability of Buckling-Restrained Braced Frames
(2023-04-19)Recent research has focused on the ability of buckling-restrained braces and their connecting elements to act together as a series of resisting elements to resist mechanism formation. This potential failure mode is known ... -
Base isolated building preformance and the impact of the national seismic hazard model
(2023-04-19)The NZSEE/MBIE recently released seismic design guidelines aiming to provide a more consistence design performance of base-isolated buildings in NZ. This paper confirms the superior performance of base-isolated buildings ... -
Dealing with uncertainty in prediction of lateral spread
(2022-04-27)Prediction of lateral spread for seismic assessment and design includes considerable uncertainty. Two widely used prediction methods are Youd et al. (2002) and Zhang et al. (2004). Five case studies across the Wellington ... -
Ductile timber connections: Understanding the factors contributing to their ductility
(2022-04-27)It is well accepted that ductility in a timber structure is achieved through its conections as the behaviour of timber is inherently brittle. It is thus important to understand the diferent parameters that contribute to ... -
Ductility factor validation for CLT walls with bolted hold-downs: preliminary analysis and observations
(2022-04-27)High-capacity cantilever CLT walls can be created with bolted hold-downs to resist earthquake loading. This study briefly presents the experimental results and cyclic behaviour of the representative test specimen. Then ... -
Investigating the effect of stiffness on the seismic performance of RC structures
(2023-04-19)This study investigates the correlation between stiffness and the seismic performance of RC structures. Structural performance was compared for buildings affected by four different earthquakes, Tokachi-Oki (1968), Chile ... -
Learning Importance Sampling Distributions via Normalizing Flows to Estimate Rare-Event Failure Probabilities
(2023-04-19)Engineered systems are typically designed to be robust and have very low probabilities of failure. However, developing accurate estimates of these probabilities can be challenging given the complex (and typically nonlinear) ... -
Modelling uncertainty induced by plastic hinge length in lumped-plasticity analysis of RC columns
(2022-04-27)This study quantifies the influence of various plastic hinge length assumptions on the uncertainty in the response of reinforced concrete (RC) columns simulated using lumped plasticity models. Although several expressions ... -
Seismic Behaviour of Slender Rectangular Reinforced Concrete Walls based on analytical methods
(2023-04-19)In the seismic design and assessment of structures, one of the key parameters is the displacement capacity of the structural elements. Slender reinforced concrete (RC) structural walls are one of the more commonly used ... -
Seismic Damage States and Damage Quantification of Light Timber Framed Walls in Residential Houses
(2023-04-19)New Zealand (NZ) has a performance-based code environment. The essence of performance-based seismic design of buildings is to achieve multiple performance requirements including damage control. However, the current seismic ... -
Seismic retrofit of historic timber structures: Uncertainties and adaption on site
(2022-04-27)Existing timber structures, containing more hand-adapted and degradable components than other materials, provide challenges in ensuring your design intent is followed through on site. Often these buildings are flexible ... -
Seismic Retrofitting Concrete Structures with Post-installed Connections in New Zealand
(2024-04-09)Seismic Retrofitting of concrete structures in New Zealand is of utmost importance, as highlighted by the most recent catastrophic Canterbury earthquakes in 2010 and 2011. With more than 2,800 earthquake-prone buildings ... -
Study on floor-slab out-of-plane effect of a 2-storey low-damage concrete wall building
(2022-04-27)In 2019, a system-level shake-table test of a 2-storey low-damage concrete wall building was conducted using the multi-functional shake-table array at Tongji University as part of an international collaborative project ...
