Innovative Resin Injection Ground Improvement to Build Up Seismic Resilience of Existing Water Structures
(2023-04-19)The existing Wellington Water’s Waterloo Water Treatment Plant (WTP) in Wellington, New Zealand is an important post-earthquake facility for the Wellington region. The WTP is founded on soils prone to liquefaction and ... -
Behaviour of Unreinforced R.C. Beam-Column Joints Under Bidirectional Loading
(2023-04-19)Modern building codes for reinforced concrete (RC) frame structures in areas susceptible to earthquakes prescribe detailing requirements for the beam-column joint to prevent shear failure and subsequent loss of gravity ... -
Dynamic Behaviour of Interlocking Plastic-block Structure Using Shake Table
(2023-04-19)Severe damage was caused by the earthquake, primarily to non-engineered structures in rural areas. Structures including roads, bridges, buildings and railroad tracks all suffered catastrophic destruction as a result of ... -
Response of Retrofitted 3D RC Frames under Dynamic Loading Conditions
(2023-04-19)In this study, the response of 3D double story reinforced concrete (RC) frames retrofitted through a diagonal friction damper under dynamic loading conditions, was evaluated using shaking table tests. A friction damper ... -
Multidirectional cyclic testing of self-centering cross-laminated timber shear wall sub-assemblies
(2023-04-19)Driven by demand for sustainable buildings, mass timber, specifically cross-laminated timber (CLT), is being more widely used in mid-rise buildings in the US. In areas of the US with a significant seismic (i.e., earthquake) ... -
Seismic application of fillet and partial penetration butt welds
(2023-04-19)Fillet and partial (incomplete) penetration butt welds are the most cost-effective weld details for structural steel connections. Correctly sized and executed, double-sided, balanced fillet welds and partial penetration ... -
Base isolated building preformance and the impact of the national seismic hazard model
(2023-04-19)The NZSEE/MBIE recently released seismic design guidelines aiming to provide a more consistence design performance of base-isolated buildings in NZ. This paper confirms the superior performance of base-isolated buildings ... -
Design of Mixed Angle Screw CLT Hold-Down Connections to New Zealand Timber Standards
(2023-04-19)Mixed angle screws provide a strong, stiff, and ductile hold-down solution for high-capacity Cross Laminated Timber (CLT) shear walls. Timber is an inherently brittle material and most inelastic responses in timber structures ... -
Review and suggestions on timber buildings with hybrid lateral force resisting systems
(2023-04-19)Timber-framed structures have long been the default structural form for residential construction in many countries, including New Zealand. However, for some complex low-rise and mid-rise buildings, hybrid Lateral Force ... -
High capacity glued-in rod connections in Cross-Laminated Timber (CLT) structures
(2023-04-19)Glued-in rods are efficient and high-capacity connections for achieving high-strength connections in new timber structures and reinforcing existing timber buildings. With the emergence of cross-laminated timber (CLT) and ... -
A Practical Approach to Design Supplemental Damped Isolation Systems
(2023-04-19)With an update to the NZS1170.5 design hazard expected in 2023, New Zealand designers will need innovative solutions in-order to manage potentially significant increases in design hazard, particularly around the lower North ... -
Investigating the effect of stiffness on the seismic performance of RC structures
(2023-04-19)This study investigates the correlation between stiffness and the seismic performance of RC structures. Structural performance was compared for buildings affected by four different earthquakes, Tokachi-Oki (1968), Chile ... -
Achieving earthquake-safe buildings – an educational initiative for developing nations
(2023-04-19)Building departments in developing nations have a poor track record of achieving earthquake-safe new buildings. Many buildings, within their jurisdictions are not expected to perform well in medium- to high-intensity ... -
Earthquake Protection of Residential Buildings: New Resilient System for Light Timber Framing
(2023-04-19)In NZ, similar to other countries, residential houses are mostly constructed using light timber framing. The common seismic solutions available in the market for such low-rise buildings are based on yielding of sacrificial ... -
A Sensitivity Study of the Design Parameters Affecting the Global Stability of Buckling-Restrained Braced Frames
(2023-04-19)Recent research has focused on the ability of buckling-restrained braces and their connecting elements to act together as a series of resisting elements to resist mechanism formation. This potential failure mode is known ... -
Examples of ground improvement applications for earthquake design
(2023-04-19)The ground improvement applications and examples in this paper are planned to augment MBIE Module 5. This paper presents some ground improvement applications and their design and specification for earthquake hazard mitigation. ... -
Developing Construction 4.0 transformation of Aotearoa New Zealand's construction sector
(2023-04-19)Aotearoa’s construction industry reached over $20.5 billion in 2019 and it became the fourth largest workplace in the year ended June 2021, significantly contributing to New Zealand’s economy. However, it has long been ... -
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 ... -
Learning Importance Sampling Distributions via Normalizing Flows to Estimate Rare-Event Failure Probabilities
(2023-04-19)Engineered systems are typically designed to be robust and have very low probabilities of failure. However, developing accurate estimates of these probabilities can be challenging given the complex (and typically nonlinear) ... -
