Seismic Restraint Design and Documentation for the Christchuch Acute Services Building
(2021-04-14)Seismic restraint design in New Zealand for large services intense buildings is a developing field. There are few examples of services intense Importance Level 4 buildings where fully compliant and modelled seismic restraint ... -
Seismic risk and the Building Code: A regulatory perspective
(2021-04-14)NZ is at the forefront of earthquake engineering and innovative solutions and strategies for dealing with seismic risk. Recent earthquakes have presented both opportunities and challenges for improving how the regulatory ... -
Seismic Strengthening Auckland's Waterfront
(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 ... -
Seismic upgrading of friction-damped steel frames integrated with self-centring devices
(2021-04-14)Conventional friction-based damping devices are known for their large energy dissipation capacity and economic benefits compared to other seismic mitigation systems. These devices have been implemented in many practical ... -
Self-drilling dowel connections for ductile link beams in coupled CLT walls
(2021-04-14)Coupled CLT walls with steel link beams can form a more efficient lateral load resisting system for tall timber buildings when compared to single CLT shear walls. To achieve adequate coupling between CLT walls and ensure ... -
SESOC Software – Seismic Design Tools
(2021-04-14)SESOC has accumulated a number of structural software design programs, over time, which we actively maintain/enhance, also on occasion developing a new tool for the benefit of our members – and the NZ design fraternity. This ... -
Shake table testing of fire sprinkler piping systems typical of New Zealand practices
(2021-04-14)An automatic fire sprinkler piping system requires an intricate piping network to feed individual sprinklers spread across the plenum space. In practice, this elaborate piping network is braced against seismic demands ... -
Simplified numerical modeling of reinforced concrete columns with smooth rebars
(2021-04-14)Pre-1970s concrete buildings in New Zealand were commonly constructed with smooth longitudinal reinforcing bars. The NZSEE guideline for the seismic assessment of existing buildings (NZSEE C5) recognizes that the seismic ... -
Source modelling insights from ground motion simulation validation of moderate magnitude active shallow crustal earthquakes in New Zealand
(2021-04-14)Hybrid broadband ground motion simulation validation has been an ongoing effort in NZ with recent studies focussed on active shallow crustal earthquakes of large magnitude (Mw>7.0) and small magnitude (3.5<Mw≤5.0). Lessons ... -
Strength requirements for non-structural components responding nonlinearly under earthquake excitation
(2021-04-14)This study develops a practice-oriented method to design non-structural components and their restraints to lower strengths than needed to remain elastic under earthquake ground motion by permitting nonlinear non-structural ... -
The 2022 New Zealand National Seismic Hazard Model Revision
(2021-04-14)We are embarking on the most significant revision of the NSHM in more than 20 years. An international team of more than 50 scientists is contributing to two working groups: 1) Seismicity Rate Models (SRM); and 2) Ground ... -
The Assessment of Liquefaction induced Settlement - application within Engineering Practice
(2021-04-14)The assessment of the magnitude of liquefaction-induced settlements affecting shallow founded buildings and buried services is an important yet challenging task for geotechnical engineers. It is often required when assessing ... -
The national seismic hazard model for New Zealand: Contributions from the deep south
(2021-04-14)The New Zealand National Seismic Hazard Model (NSHM) is being updated for the first time since 2010 in a multi-institutional project led by GNS Science (www.gns.cri.nz/NSHM). In the interim, several major well-instrumented ... -
The Optimised Sliding Hinge Joint (OSHJ): Design, Detail, and Implementation in Practice
(2021-04-14)The Optimised Sliding Hinge Joint (OSHJ) is a low-damage, resilient, versatile, and cost effective seismic resisting system developed primarily for Moment Resisting Steel Framed (MRSF) buildings. The OSHJ is the optimized ... -
The State of Practice in SSI Modelling in New Zealand: Insights from an Engineering Profession Survey
(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 ... -
The top enablers and barriers of seismic technology adoption in construction
(2021-04-14)The slow process of adoption of the new technologies has been identified as a significant issue in the construction industry. In order to address this issue, the top enablers and barriers of the adoption process are needed ... -
