Webinar – Optimized Sliding Hinge Joint (OSHJ)
November 18, 2020 @ 8:30 am - November 19, 2020 @ 2:00 pm
The Optimised Sliding Hinge Joint (OSHJ) is a low damage, highly seismic resilient, versatile, and cost effective seismic resisting connection developed primarily for Moment Resisting Steel Framed (MRSF) buildings. The OSHJ is the optimized version of the traditional Sliding Hinge Joint (SHJ) with Asymmetric Friction Connections (AFCs).
The presentation will discuss the advantages, the recent development, modelling, designing, detailing, and in-service use of OSHJ.
Key Aspects to be covered:
- Moment resisting frames (MRFs)
- Improvements in MRFs seismic performance
– Traditional Sliding Hinge Joint (SHJ) with Asymmetric Friction Connections (AFCs)
– Background and developments
– Seismic behaviour
– Imperfections - Optimised Sliding Hinge Joint (OSHJ)
– Recent developments and key improvements compared with the traditional SHJ, making OSHJ a true Low damage (no damage) system
– Modelling and seismic loading of the building
– Design actions of the OSHJ beam and column
And much more….

Dr. Shahab Ramhormozian | Lecturer at Auckland University of Technology (AUT)
Shahab is a Lecturer at Auckland University of Technology (AUT) teaching, and undertaking and supervising research in the field of structural and earthquake engineering with a focus on steel structures. Shahab has undertaken his PhD under Associate Professor Charles Clifton’s supervision on optimising the Sliding Hinge Joint with Belleville Springs, which has started to be implemented in practice.
Dr Charles Clifton | Associate Professor, University of Auckland
Dr Clifton is an Associate Professor at University of Auckland, specialising in structural steel and composite engineering in both heavy and light gauge steel. Charles has worked with Shahab Ramhormozian in developing the optimised sliding hinge joint to the point where it is now the most cost-effective, best performing and versatile low damage solution available worldwide for moment resisting steel framed seismic resisting systems
