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 ...
