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 ...
A holisic methodology for assessing post-earthquake hospital functionality
(New Zealand Society for Earthquake Engineering, 2021-04-14)
Hospitals play a critical role in ensuring community safety. Hospitals must remain operational during and after an earthquake. However, physical damage, utility outages, or supply shortages can cause closures and/or ...
Earthquake prone public buildings: balancing life safety risks and community costs
(New Zealand Society for Earthquake Engineering, 2021-04-14)
The focus on seismic risk following the 2011 Christchurch and 2016 Kaikoura earthquakes has seen the closure of several public buildings across the country. The introduction of the Building (Earthquake-prone Buildings) ...
Balancing seismic resilience and lean design to reduce the embodied carbon of buildings
(New Zealand Society for Earthquake Engineering, 2021-04-14)
The building and construction sector needs to make big changes to reduce greenhouse gas emissions if New Zealand is going to meet the legally binding targets of the 2019 Zero Carbon Act, and its commitments under the Paris ...
Managing Seismic Risk across Process and Manufacturing Facilities
(New Zealand Society for Earthquake Engineering, 2021-04-14)
To manage seismic risk at large Process and Manufacturing Facilities requires a PCBU to understand the compliance requirements from legislation. However this is not an easy task as there are multiple Acts, Regulations, ...
Seismic Strengthening Auckland's Waterfront
(New Zealand Society for Earthquake Engineering, 2021-04-14)
Seawalls were constructed in sections between 1879 and 1925 to form Quay Street on the waterfront of Downtown Auckland. These seawalls have essentially remained structurally unchanged since they were first constructed and ...
A Typical Commercial Low Rise Structure - Case Study
(New Zealand Society for Earthquake Engineering, 2021-04-14)
The Case study building was designed and built in 2003. The building is a single storey rectangular shaped 25m x 21m steel portal frame structure with precast concrete panels. The building is typical of a modern commercial ...
An automation approach to the seismic assessment and strengthening of unreinforced masonry buildings
(New Zealand Society for Earthquake Engineering, 2021-04-14)
Large scale seismic assessments in areas of dense unreinforced masonry buildings (URM) is a significant challenge for structural engineers. URM buildings respond to earthquake excitation with a variety of mechanisms as ...
Seismic performance expectations of homeowners using strengthening techniques to structurally prepare houses for earthquakes
(New Zealand Society for Earthquake Engineering, 2021-04-14)
Due to the widespread damage and large economic losses caused to residential houses by major earthquakes all around the world, government authorities and nongovernmental organizations have made significant investments to ...
