Prof. Aleksandar Pavic

Aleksandar PavicProfessor Aleksandar Pavic is a graduate (1988) of the Faculty of Civil Engineering, University of Belgrade in the former Yugoslavia and worked as a bridge engineer and at his alma mater before coming to the UK in 1992. He was appointed a Lecturer at the University of Sheffield, Department of Structural Engineering in January 1996 after spending just over two years as a doctoral student in the Department. This was followed by promotions to a Senior Lecturer in October 2002 and a Personal Chair in Vibration Engineering in March 2004. Two months later, in May 2004, he became a research professor following his award of a prestigious 5-year Advanced Research Fellowship funded by the UK Engineering and Physical Sciences Research Council (EPSRC) to work on a novel Stochastic approach to human-structure dynamic interaction.

At the University of Exeter, Professor Pavic heads the Vibration Engineering Section which, after 20 years of highly successful academic operation, transferred from the University of Sheffield in May 2013. His research portfolio is focused on vibration performance of civil engineering structures. His particular expertise is in vibration serviceability of slender civil engineering structures, such as long-span floors, footbridges and grandstands, which are occupied and dynamically excited by humans. This portfolio is underpinned by advanced research tools such as vibration testing and system identification of as-built large civil engineering structures using full-scale modal testing and finite element model correlation and updating based on experimental measurements. This is a high-tech approach to structural vibration widely used in mechanical and aerospace engineering disciplines, parts of which have been adapted and transferred into civil engineering applications by Professor Pavic and his team. He has authored and co-authored more than 100 publications including more than 50 refereed journal papers.

Professor Pavic has edited two special issues of international journals devoted to vibration performance of civil engineering structures: a special issue on Vibration Serviceability published by ICE Proceedings Structures and Buildings (2006); and a special issue on Crowd Dynamic Loading of Assembly Structures published by Shock and Vibration (2007). His contribution has been recognised in three key recently published state-of-the-art design guidelines which are currently used in the UK and internationally when checking vibration serviceability of floors and footbridges. These were published by:

  • The Concrete Society (Technical Report 43, Appendix G: Vibration Serviceability of Post-Tensioned Concrete Floors) in 2005,
  • The Concrete Centre (A Design Guide for Footfall Induced Vibration of Structures) in 2007, and
  • The Steel Construction Institute (Design of Floors for Vibration: A New Approach) in 2007.

Professor Pavic has also co-authored and helped experimental verifictaion of the most advanced design guidelines in the world on crown dynamic loading of grandstands published by the UK Institution of Structural Engineers (2008). He sat on committees for the British Standards Institution (BS6472) and the International Standardisation Organisation (ISO10137) to develop standards pertinent to vibration serviceability.

Professor Pavic’s expertise is sought after by industry and he is Managing Director of Full Scale Dynamics Ltd, a university spin-off of comapny specialised in commercial testing, monitoring and performance assesement of full-sclae civil enngineering structures.
