Biography:

Pouyan has joined AUT after being as a postdoctoral research fellow at UoA where he graduated with a PhD. His research interests lie in the areas of connections, earthquake-resistant technologies and timber-based hybrid structures. His research findings have been recognised internationally through more than 40 publications including patents, design book and book chapters, papers in top scientific journals and international conferences.

His new design approach associated with the potential brittle, mixed and ductile failure modes of small-dowel-type timber connections under parallel and perpendicular to grain loading directions in different engineered timber products is considered for adoption in the next edition of the New Zealand NZS 3603 Timber Standards where he is a committee member. His contribution has been acknowledged as the "most comprehensive piece of work on the issue of timber connections" by Prof Ian Smith (distinguished scholar in Structural and Timber Engineering, winner of James Croes Medal and member of Canadian CSA-O86 Standard).

He is the inventor of the novel Resilient Slip Friction (RSF) joint (winner of Spark's $100k Challenge) which provides an advanced engineering solution for seismic damage avoidance design of buildings either in steel, timber or concrete. He is the science leader of a MBIE research project ($3.4M) in collaboration with Prof Pierre Quenneville from UoA as the co-science leader for implementation of this new technology which has the capacity of dissipating earthquake energy as well as self-centring with no post event maintenance to minimize the damage and the residual drift of the structure. Pouyan has also over 10 years of invaluable practical experience achieved through his involvement in professional civil projects as Civil Engineer, Head of Civil Engineering Office, Deputy Site Manager, Structural Engineer, and Chief Technical Officer.

Research Areas:

My research interests lie in the areas of connections, earthquake-resistant technologies and timber-based hybrid structures including:

• High capacity and damage-avoidance connections to be used for different types of structures
• Brittle, mixed, and ductile failure modes of timber connections under lateral forces and moment
• Theoretical (stiffness-based/fracture mechanics), numerical, and experimental analyses
• Multi-story and long-span structures using new engineered timber products
• Hybridization techniques for composite structures (timber-steel, timber-concrete, timber-cold formed steel, and timber-masonry)
