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 modelling 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
