Optimising seismic resilience assessments -Part II:Integrating geophysical and geotechnical investigations
(New Zealand Society for Earthquake Engineering, 2023-04-19)
In a country frequently shaken by earthquakes, understanding the risk to infrastructure from seismic shaking is a vital part of any construction project. With no single technique able to fully capture the seismic hazard ...
Seismic Damage States and Damage Quantification of Light Timber Framed Walls in Residential Houses
(New Zealand Society for Earthquake Engineering, 2023-04-19)
New Zealand (NZ) has a performance-based code environment. The essence of performance-based seismic design of buildings is to achieve multiple performance requirements including damage control. However, the current seismic ...
Mitigation of liquefaction-induced lateral spread ground displacements using an in-ground pile wall
(New Zealand Society for Earthquake Engineering, 2023-04-19)
Liquefaction-induced lateral spread ground displacements can be damaging to buildings and their foundations. Buildings can either be designed/strengthened to tolerate such displacements, or ground improvement (e.g. compaction, ...
Performing Structural Assessment using Acoustic Measurements
(New Zealand Society for Earthquake Engineering, 2023-04-19)
Natural hazards, such as earthquakes, could be catastrophic. One challenge that society faces is how to provide a rapid and accurate evaluation of the structural damages after the events. Traditional visual inspection is ...
Multistage Friction Connections
(New Zealand Society for Earthquake Engineering, 2023-04-19)
Multistage friction connections (MFCs) are bolted connections for dissipating seismic energy while reducing peak displacements and encouraging recentring. MFCs comprise two symmetric friction connections co-linearly ...
Seismic strengthening of RC walls using FRP to prevent axial failure
(New Zealand Society for Earthquake Engineering, 2023-04-19)
Reinforced concrete (RC) walls with insufficient compressive strain capacity at the boundary region are vulnerable to premature axial failure, limiting the drift capacity. A solution to strengthen these deficient RC walls ...
Low Damage Wall To Floor Connections For Seismic Resilient Timber Structures
(New Zealand Society for Earthquake Engineering, 2023-04-19)
Rocking timber walls provide superior seismic performance in comparison with conventional light timber structures. Nevertheless, there is an uplift movement at the base of the wall that is translated as vertical displacement ...
Cyclic behavior of older concrete columns reinforced with high-performance fiber reinforced cementitious composites
(New Zealand Society for Earthquake Engineering, 2023-04-19)
Many older existing reinforced concrete (RC) buildings were designed without considering seismic loads. In such buildings, columns may be the most vulnerable element because they generally have insufficient reinforcement ...
