After graduating from Sts Cyril and Methodius University in 1982, Mihail Petkovski worked for 11 years in the Institute for Earthquake Engineering and Engineering Seismology (IZZIS) in Macedonia, as a research associate (1982-1990) and lecturer (1990-1993). He worked on research projects involving (i) quasi-static tests of steel structure assemblies, (ii) in-situ dynamic testing of full scale structures and (iii) shaking table testing of reduced scale models of concrete and masonry buildings and prototypes of structures for high-voltage networks and equipment for nuclear power plants. During this period Mihail obtained an MSc degree in Earthquake Engineering.

Mihail joined The University of Sheffield in 1993 as a PhD Student. In 1997 he was employed by as a research associate in the Department of Civil and Structural Engineering. In the period between 1997 and 2001 he developed mac2T, Sheffield’s unique facility for multiaxial compression of concrete at elevated temperature. Mihail designed and commissioned the hardware and wrote the software for data acquisition and control of the rig. In the last 10 years mac2T was used for over 300 complex multi-stage experiments, in a succession of research projects funded by EPSRC, EU, UK government and Industry (Nuclear Electric/British Energy, MOD/QinetiQ). In 2007 Mihail was appointed Lecturer in Structural Dynamics in the Department of Civil and Structural Engineering at The University of Sheffield.

Recent activities and achievements

Experimental continuum mechanics of pressure sensitive materials:

  • concrete at elevated temperature: effects of heat-load regimes on mechanical properties and changes in the microstructure of concrete, with a focus on LITS (load induced thermal strain);
  • concrete and rock under multiaxial compression: relationship between development of damage in the material and the macroscopically observed stress-strain behaviour (of test specimens).

Earthquake engineering of multi-storey buildings:

  • structural systems for improved seismic behaviour of buildings: connections and plastic hinge regions in steel and concrete frames;
  • systems for control of the seismic response of frames: passive friction/yield connections and semi-active control.
