Validation of NZ small-magnitude ground-motion simulations using complex structural systems
(New Zealand Society for Earthquake Engineering, 2021-04-14)
This study assesses the need to consider complex structural models in ground-motion simulation validation. It develops a novel statistical framework to quantify the proportion of the differences in structural responses ...
Assessment of boundary conditions for 2D geotechnical site-response analysis with soil heterogeneity
(New Zealand Society for Earthquake Engineering, 2021-04-14)
This paper examines various boundary condition assumptions for modelling 2D geotechnical site response, which requires a more sophisticated treatment of the boundary and loading conditions than what is typically required ...
Parallel scalability of OpenSees for 2D and 3D ground response analysis problems
(New Zealand Society for Earthquake Engineering, 2021-04-14)
This study investigates the parallel scalability of the OpenSees finite element analysis platform in the context of 2D and 3D ground response analyses. A series of 2D and 3D models ranging from 7500 to 480000 elements are ...
The State of Practice in SSI Modelling in New Zealand: Insights from an Engineering Profession Survey
(New Zealand Society for Earthquake Engineering, 2021-04-14)
There is a relatively brief consideration for soil-structure interaction (SSI) effect in the New Zealand guidelines for the seismic assessment of structures. Recent earthquake events including the Kaikōura earthquake of ...
