Establishing the Transverse Load Capacity of a Timber-framed Classroom Block
(2023-04-19)In 2013, longitudinal testing of single storey timber-framed classroom blocks was initiated by the Ministry of Education and completed by BRANZ to better understand the seismic resilience of timber-framed buildings within ... -
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 ... -
Development, verification, and validation of a buckling-fatigue steel material model
(2023-04-19)Currently, there are limited constitutive models available in finite element analysis packages that reliably capture the coupled effects of bar buckling and fatigue. However, such a model is needed for reliable estimation ... -
Field miniature prototype development and pilot project design of subsurface compacted Rubble Raft (SCRR)
(2023-04-19)Subsurface Compacted Rubble Raft (SCRR) is a patented wide-area ground improvement solution that focuses on solving severe liquefaction hazards. SCRR technique directly targets the liquefaction layers by constructing a ... -
Reimagining Community Resilience through a Te Ao Maori Worldview
(2023-04-19)Efforts to improve community resilience have seen universal efforts to grow capabilities in disaster management for the built environment. Although comprehensive frameworks exist, the perspective used to derive 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 ... -
Predictive models for changes in reinforcement characteristics due to strain ageing effects
(2023-04-19)One of the factors affecting repair feasibility of buildings damaged by earthquakes is the potential effects of strain ageing of reinforcement. Since strain ageing can lead to an increase in structural member strength and ... -
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 ... -
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 ... -
Case Study for Seismic Assessment of an Existing Asymmetric non-prismatic Unique Reinforced Concrete- encased Steel Plate Column in Wellington
(2023-04-19)This case study presents a tailored approach to assessing a high-rise building in the Wellington CBD constructed primarily from reinforced concrete encased steel frames. This construction is rare in New Zealand, and it is ... -
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 ... -
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 ... -
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 ... -
Feasibility of capacity spectrum method for analysis of low damage structural systems with friction connections
(2023-04-19)The use of friction connections for low damage design of new structures has been increasing over the past few years. These connectors have a high energy dissipation ratio and are relatively economical to fabricate and ... -
Earthquake Design Pressures from Soil Interaction on Building Basement Walls
(2023-04-19)Free-standing retaining walls are usually designed for earthquake loads using the Mononobe-Okabe method and assuming cohesionless soil backfill. The method assumes active pressure develops as a consequence of a failure ... -
Post-disaster building functionality: preliminary findings of a systematic review
(2023-04-19)During a natural hazard event, buildings are likely to experience some sort of damage, thus limiting their ability to function as intended. The severity of the ensuing consequences for various stakeholders and the community ... -
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 ... -
Deformability of lap splices in RC structural walls
(2023-04-19)Severe structural damage associated with lap splices located near the foundation of reinforced concrete (RC) structural walls has been recorded in the field after recent major earthquakes in Chile, New Zealand, and Taiwan. ... -
