Finite Element Convergence Study of the Asymmetric Friction Connection (AFC) in the Optimised Sliding Hinge Joint (OSHJ)
(New Zealand Society for Earthquake Engineering, 2023-04-19)
The Optimised Sliding Hinge Joint (OSHJ) is a cost-effective, low damage seismic resisting beam-column connection developed for Moment Resisting Steel Framed (MRSF) buildings. The OSHJ is the optimised version of the ...
Elongating plastic hinge element for nonlinear analysis of RC structures using OPENSEES
(New Zealand Society for Earthquake Engineering, 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 ...
“Modal crimes” in structural engineering
(New Zealand Society for Earthquake Engineering, 2023-04-19)
With increasing seismic hazard as advised by the NSHM 2022 for entire New Zealand, there is a huge demand for the retrofit of existing building stock to achieve higher earthquake resilience. One of the ways to achieve a ...
Shake-table testing of resilient, low-cost seismic isolators based on rolling rubber spheres
(New Zealand Society for Earthquake Engineering, 2023-04-19)
This study presents the results of a large-scale experimental investigation of resilient, low-cost seismic isolators based on deformable rubber spheres. The isolators roll on flat or spherical (concave) concrete surfaces. ...
Effect of Periodic Unit Cell Volume on Attenuation Zones of 1D-Meta-material based Periodic Foundations
(New Zealand Society for Earthquake Engineering, 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, ...
Behaviour of Unreinforced R.C. Beam-Column Joints Under Bidirectional Loading
(New Zealand Society for Earthquake Engineering, 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 ...
Response of Retrofitted 3D RC Frames under Dynamic Loading Conditions
(New Zealand Society for Earthquake Engineering, 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
(New Zealand Society for Earthquake Engineering, 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
(New Zealand Society for Earthquake Engineering, 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 ...
Review and suggestions on timber buildings with hybrid lateral force resisting systems
(New Zealand Society for Earthquake Engineering, 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 ...
