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. ... -
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 ... -
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 ... -
A prescriptive method for the design of new steel moment frame structures with supplemental damping
(2023-04-19)This paper presents a prescriptive method for the design of new steel moment frame structures with supplemental damping using fluid viscous dampers. The prescriptive method uses Modal Response Spectrum Analysis (MRSA) ... -
A quantitative risk assessment of seismic slope stability for a tailings dam
(2023-04-19)Tailings are a by-product of mining, consisting of silts and sands from the processed rock or soils and susceptible to liquefaction under earthquakes. Tailings Storage Facilities (TSFs) include dams that are designed and ... -
A Review of Practice-Oriented Methods for Estimating Seismic Demands on Parts and Components
(2023-04-19)A variety of methods for the estimation of demands on building parts and components have been proposed in international codes and the literature. These have been reviewed as part of recent research co-funded by QuakeCoRE, ... -
A Review of the State of Practice for Fluid Viscous Damper Applications in North America and New Zealand
(2023-04-19)The use of Fluid Viscous Dampers (FVDs) for retrofit and new construction applications is growing around the world. FVDs provide an effective way to reduce seismic demands on structures. In retrofit applications, this ... -
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 ... -
Accounting for the Influence of Intrinsic Soil Properties and State Variables on Liquefaction Triggering
(2023-04-19)Current simplified liquefaction triggering procedures are limited in their ability to capture the effects of intrinsic properties (grain size, mineralogy, grain shape, etc.) and the state properties (stress state, void ... -
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 ... -
Advanced seismic design of concrete-to-concrete structural connections
(2023-04-19)Seismic strengthening of concrete buildings and bridges may require the addition of new concrete members or overlays. One way of connecting new concrete to existing concrete is using post-installed rebar (PIR) connections. ... -
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 ... -
Assessment of lateral spread potential used smeared strengths of liquefied/non liquefied soils
(2023-04-19)Liquefaction-induced lateral ground displacements (lateral spread) are typically assessed using empirical methods where a continuous weak (liquefied) layer is expected. These methods are not appropriate for variable fill ... -
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 ... -
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 ... -
Behaviour of Unreinforced R.C. Beam-Column Joints Under Bidirectional Loading
