Teaching Areas

  • Engineering Mechanics;
  • Structural Analysis and Design;
  • Concrete Structures

Research Areas

  • Serviceability of concrete and composite structures. This involves the development of analytical models for the time-dependent in-service behaviour of reinforced and prestressed concrete structures and steel-concrete composite structures, including beams, slabs, columns, shallow arches and domes;
  • Creep and shrinkage of concrete and the effects of creep and shrinkage in concrete structures;
  • The impact of low ductility reinforcement on the strength and ductility of reinforced concrete members and structures;
  • Finite element modeling of concrete structures, involving the development of FE models that realistically account for material non-linearity and, where appropriate, geometric non-linearity;
  • Structural applications of high strength concrete and reactive powder concrete, including flexural and non-flexural members; and
  • Time-dependent behaviour of reinforced concrete arches and axisymmetric domes
