Modelling uncertainty induced by plastic hinge length in lumped-plasticity analysis of RC columns
(New Zealand Society for Earthquake Engineering, 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 ...
Ductility factor validation for CLT walls with bolted hold-downs: preliminary analysis and observations
(New Zealand Society for Earthquake Engineering, 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 ...
Seismic retrofit of historic timber structures: Uncertainties and adaption on site
(New Zealand Society for Earthquake Engineering, 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 ...
Dealing with uncertainty in prediction of lateral spread
(New Zealand Society for Earthquake Engineering, 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 ...
Study on floor-slab out-of-plane effect of a 2-storey low-damage concrete wall building
(New Zealand Society for Earthquake Engineering, 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 ...
Ductile timber connections: Understanding the factors contributing to their ductility
(New Zealand Society for Earthquake Engineering, 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 ...
A quantitative risk assessment of seismic slope stability for a tailings dam
(New Zealand Society for Earthquake Engineering, 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 ...
Seismic Behaviour of Slender Rectangular Reinforced Concrete Walls based on analytical methods
(New Zealand Society for Earthquake Engineering, 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 ...
Base isolated building preformance and the impact of the national seismic hazard model
(New Zealand Society for Earthquake Engineering, 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 ...
Investigating the effect of stiffness on the seismic performance of RC structures
(New Zealand Society for Earthquake Engineering, 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 ...
