Numerical parametric analysis of gravity column base-plate connections
(2023-04-19)Gravity column base-plate connections are normally treated as pinned connections in design. Correspondingly, a low rotational stiffness value is specified in the New Zealand steel design standard, NZS 3404. However, previous ... -
Numerical Investigation of Australasian Cold-Formed Steel strap-braced walls under lateral and vertical load
(2023-04-19)Cold-Formed Steel (CFS) gained popularity in residential buildings due to its dimensional accuracy, lightweight, resistance to shrinking and creeping, durability, low embodied carbon and CNC manufacturing abilities. The ... -
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) ... -
A New Rocking Concrete Shear Wall with Self-Centring Friction Connections
(2023-04-19)In recent years, the intention towards developing and utilising low-damage systems in seismic resisting structures has been increasing amongst researchers and engineers. Replaceability and repairability after earthquakes ... -
Performing Structural Assessment using Acoustic Measurements
(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 ... -
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 ... -
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 ... -
A displacement-based design method of low-damage dual systems with hysteretic and nonlinear viscous energy dissipation
(2023-04-19)In 2019, a large shaking-table test was performed for a full-scale two-storey low-damage concrete wall building. The test building comprises unbonded post-tensioning (UPT) rocking walls and perimeter frames in both directions. ... -
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 ... -
Risk thresholds in the built environment
(2023-04-19)Engineering and building design inherently deal with risk. But risk is rarely—if ever—explicitly considered. Most building design in Aotearoa New Zealand (i.e., to B1/VM1 NZS1170) targets an annual individual fatality risk ... -
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 ... -
Public expectations of damage and disruption to existing multi-storey buildings in earthquakes
(2023-04-19)The seismic performance of both structural and non-structural building components have the potential to affect the lives of building occupants, with poor performance likely to cause undue disruptions to the lives of building ... -
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 ... -
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 ... -
Evaluation of prioritization schemes for bridge stock assessment
(2023-04-19)The important role of bridges in transportation network resiliency has made the management of the existing bridge stock an essential task. In order to implement and prioritise the activities to secure the proper performance ... -
Elongating plastic hinge element for nonlinear analysis of RC structures using OPENSEES
(2023-04-19)During inelastic cyclic loading, the length of plastic hinges in reinforced concrete (RC) members increases irreversibly which significantly affects the seismic performance of RC structures. It is hence necessary for ... -
Cyclic behavior of older concrete columns reinforced with high-performance fiber reinforced cementitious composites
(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 ... -
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 ... -
Area Ratio or Volumetric Ratio: Which is better for quantifying the confinement of concrete?
(2023-04-19)Confinement of concrete helps in improving ultimate strain of concrete. This increase depends on amount of transverse reinforcement in the vertical member. While the need for 1350 hooks in transverse reinforcement is ... -
Avoiding moat wall pounding of base-isolated buildings using D3 viscous dampers
(2023-04-19)Base-isolated buildings are typically important facilities expected to remain functional after a major earthquake. Seismically isolated buildings can experience large displacements at the isolation level during strong ...
