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 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 ... -
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. ... -
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 ... -
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 ... -
Chevron Buckling Restrained Brace Frame Seismic Behaviour Considering Out-of-Plane Effects
(2023-04-19)This project evaluates the behaviour of buckling restrained braces (BRBs) in a chevron configuration considering IP and OOP frame deformations using software capable of second-order inelastic frame analysis. Initially a ... -
Comparison of optimal versus a convenient distribution method of viscous damper design
(2023-04-19)A simple and convenient method often adopted by practicing engineers designing supplemental viscous dampers to a building is to calculate damping coefficients of viscous dampers corresponding to a desired added damping ... -
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 ... -
Dynamic analysis of tall reinforced concrete walls designed with minimum vertical reinforcement
(2023-04-19)Analysis of tall walls subjected to the earthquake ground motions highlights the amplified dynamic moment response at the mid-height due to the higher mode effect. The amplified moment demand may result in unexpected ... -
Effect of Periodic Unit Cell Volume on Attenuation Zones of 1D-Meta-material based Periodic Foundations
(2023-04-19)The meta-material-based periodic foundations are being investigated by researchers for earthquake engineering applications due to their wave-filtering ability. The periodic foundations are characterized by frequency bandgaps, ... -
Effect of serviceability and over-strength mechanism on seismic response of low damage structures
(2023-04-19)Low-damage structural systems are designed in a way the earthquake damage is controlled and localised in pre-designated locations and components (e.g. fuses). These components are normally replaced, repaired or designed ... -
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 ... -
