Seismic design of suspended lightweight ceilings – what’s the ductility?
(2023-04-19)In the last few years, the design of suspended ceilings has gone through significant change and the level of compliance required has increased substantially. This was largely due to the generally poor performance of these ... -
Seismic hazard analysis for a bridge across Marikina River with consideration of near-fault effects
(2023-04-19)The Valley Fault System in Metro Manila, Philippines is widely considered to be an impending threat in releasing a large-scale earthquake. Such earthquake is forecasted to impose severe casualties and economic losses to ... -
Seismic Performance Comparison of New Zealand and Japanese Concrete Moment Frames
(2023-04-19)Observations of the performance of reinforced concrete (RC) buildings after the 2016 Kumamoto earthquake in Japan showed buildings designed using Japanese standards resulted in less damage and downtime compared to buildings ... -
Seismic Restraint of Non-Structural Elements – Evolving Design Thinking
(2023-04-19)Seismic Restraint of non-structural elements has received increased attention in the past decade within the New Zealand building industry. Clients and Project Managers are now often coupling Seismic Restraint design with ... -
Seismic strengthening of RC walls using FRP to prevent axial failure
(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 ... -
Shake-table testing of resilient, low-cost seismic isolators based on rolling rubber spheres
(2023-04-19)This study presents the results of a large-scale experimental investigation of resilient, low-cost seismic isolators based on deformable rubber spheres. The isolators roll on flat or spherical (concave) concrete surfaces. ... -
Shaking Table Tests on RC Frames strengthened with Simplified Friction Damper
(2023-04-19)This study investigates the behavior of two reinforced concrete (RC) frames strengthened with simplified friction damper subjected to dynamic loading conditions. The simplified friction damper was designed with intent to ... -
Simplified approach to rapidly predict road blockages caused by co-seismic landslides
(2023-04-19)The 2016 Kaikōura earthquake triggered tens of thousands of landslides leading to several road blockages which isolated the population in Kaikōura and disrupted the transport services across the South Island. The prediction ... -
Site-specific seismic hazard analysis - evolving developments in practice
(2023-04-19)Site-specific hazard analyses (SSHAs) are undertaken to inform seismic actions for the design of important projects in New Zealand. These have typically adopted the 2010 National Seismic Hazard Model (NSHM) as the reference ... -
Site-specific seismic hazard evaluation of critical bridge infrastructure in Cebu, Philippines
(2023-04-19)Long-span, inter-island bridges in active tectonic regions are exposed considerably to elevated seismic risks. Evaluation of the seismic hazard is a primary step to assess this risk. Baseline information can be obtained ... -
Societal Expectations for Functional Recovery of Primary and Secondary School Buildings
(2023-04-19)In the ongoing investigation of functional recovery requirements, the spectrum of functional requirements for different facility types is necessary to ensure buildings are designed, constructed, and maintained to meet ... -
Source of numerical non-convergence in the analysis of bilinear SDOF systems
(2023-04-19)Numerical non-convergence is an important factor impeding the research into and widespread adoption of the nonlinear dynamic analysis. Upon encountering non-convergence at an analysis time step when using an implicit time ... -
Testing of heavily damaged reinforced concrete walls repaired using concrete and steel replacement
(2023-04-19)Post-earthquake damage assessments are essential to decisions on the need for and extent of structural repairs. Despite this, New Zealand currently has no official guidelines to evaluate the residual capacity of ... -
The next generation of drywall construction for low-damage design
(2023-04-19)Low-damage structural systems that can withstand large earthquakes with no structural damage, or localised damage in pre-defined fuses, have become commonplace in the past one to two decades. These systems however, generally ... -
Three-dimensional numerical simulation of tsunami-borne debris-loads on bridges
(2023-04-19)Tsunamis are natural disasters that sometimes follow large-magnitude offshore earthquakes and cause significant damage to coastal bridges. In addition to the destructive power of the tsunami bore, shipping containers and ... -
Timber-based seismic retrofit of a 5-storey RC structure built in 1955
(2023-04-19)The paper presents a study on the seismic behaviour of a 1955 masonry-infilled reinforced concrete (RC) building subjected to two alternative timber-based interventions to reduce its seismic vulnerability. The first ... -
Trends in systematic site residuals with geomorphic categories for New Zealand ground-motion instrument sites
(2023-04-19)This study investigates systematic site-effects from prediction residuals of physics-based ground-motion simulations for a database of small magnitude (i.e., 3.5 ≤ MW ≤ 5) shallow crustal earthquakes in New Zealand. The ... -
Understanding and Improving the Seismic Resilience of Hospital Buildings
(2023-04-19)The establishment of Te Whatu Ora – Health New Zealand has enabled more direct national oversight of public hospital buildings across New Zealand. This has also led to the need for a more comprehensive understanding of ... -
Using 3D geological models to create maps of estimated Vs30 and site period
(2023-04-19)The 30-m time-averaged shear-wave velocity (Vs30) and the fundamental site period (T0) are useful parameters for understanding site conditions, informing geotechnical studies as well as infrastructure planning. Unfortunately, ... -
Using holistic design to improve the seismic performance of non-structural elements and building resilience
(2023-04-19)Non-structural elements typically contribute around 80% of the total cost of a building. Damage to these components as well as works to repair and replace earthquake damaged non-structural elements can mean buildings are ...
