Developments in the use of high resolution point cloud data to inform heritage restoration
(New Zealand Society for Earthquake Engineering, 2021-04-14)
While considered an emerging technology at the time of the Canterbury Earthquakes, extensive use of laser scanning derived point cloud data over the last 10 years has resulted in refined processes with new and existing ...
Enhancing seismic performance of existing buildings using viscous dampers for Forward-Directivity Earthquakes – The Challenges
(New Zealand Society for Earthquake Engineering, 2021-04-14)
Enhancing the performance of an existing building with viscous dampers for a Wellington site requires thorough consideration of near-fault effects, the Wellington Fault being so close. Earthquake records with forward-directivity ...
Rapid, automated, post-earthquake building assessment using a swarm of drones and machine learning techniques
(New Zealand Society for Earthquake Engineering, 2021-04-14)
Completing safety evaluations of buildings is critical for the health and safety of a city’s community following a damaging earthquake. Most contemporary post-earthquake evaluations involve groups of people who physically ...
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 ...
Full Waveform Tomography for the upper South Island region, New Zealand
(New Zealand Society for Earthquake Engineering, 2021-04-14)
In this paper, we apply Full Waveform Tomography (FWT) based on the Adjoint-Wavefield (AW) method to iteratively invert an existing 3-D geophysical velocity model for the upper South Island region, New Zealand. Through the ...
