Research

Dr. Saatcioglu’s research primarily focuses on behaviour and design of reinforced concrete structures subjected to earthquake and blast loads. He has conducted extensive experimental and analytical research on developing design methodologies for earthquake and blast resistant structures, as well as analytical tools for inelastic behaviour of concrete and reinforced concrete structural elements. His research extends to masonry buildings and the use of fibre reinforced polymers (FRP) in reinforced concrete structures both for retrofitting sub standard structural elements and new structures with internal FRP reinforcement. Dr. Saatcioglu’s research can be grouped into two categories; i) retrofit of existing buildings and bridges that do not conform to the provisions of current codes and standards, and ii) design of new structures. The following are the highlights of Dr. Saatcioglu’s research:

Earthquake Resistant Reinforced Concrete Structures

  • Confinement of compression concrete in columns
  • Displacement-based design of reinforced concrete columns for column confinement
  • Behaviour and design of low-rise reinforced concrete shear walls

  • Retrofit of non-ductile reinforced concrete frame buildings by buckling strained braces
  • Retrofit of reinforced concrete columns by transverse prestressing (RetroBelt System)
  • Retrofit of reinforced concrete columns with FRP jackets
  • Retrofit of masonry infill walls by surface-bonded FRP
  • Retrofit of masonry load bearing walls using surface-bonded FRP with or without ductile steel sheet anchors
  • Retrofit of Reinforced concrete and masonry walls with steel strips

  • Blast retrofit of masonry walls with FRP and Polyurea
  • Development of window retention anchors against blast loads
  • Blast risk mitigation

    Development of Analytical Tools

    • Confinement model for normal-strength and high-strength concrete
    • Hysteretic models for flexure-axial load interaction, inelastic shear, anchorage slip and FRP reinforced concrete elements
