Assessment of boundary conditions for 2D geotechnical site-response analysis with soil heterogeneity
de la Torre, Christopher; Bradley, Brendon; McGann, Christopher (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
Eskandarighadi, Mohammad; McGann, Christopher; Hyde, Chris; Trow, Lily; Wang, Sirui (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
Hnat, Theo; McGann, Christopher; Wotherspoon, Liam (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 ... -
Validation of NZ small-magnitude ground-motion simulations using complex structural systems
Loghman, Vahid; Bradley, Brendon; Chandramohan, Reagan; Lee, Robin; McGann, Christopher (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 ...
