Department of Civil & Infrastructure Engineering,
Technological Educational Institute of Athens.

Research Areas:

  • Development of hybrid boundary element and finite element methods for the analysis of laminated or very thick structures. Implementation of a layer-wise Analog Equation modeling in the numerical scheme produces a meshless approach for the analysis of thick plates having arbitrary shape. Publications: [1], [13], [15].
  • Inclusion of infill masonry walls in the numerical analysis of reinforced concrete structural systems. Dynamic analysis of buildings in order to determine its response under earthquakes, study the effect of the masonry infill, of the open ground floor (pilotis) and soft-storeys. The infilled frames along with the shear walls are considered to be two-dimensional plane elastic substructures and they are modeled using the boundary element method along with subregioning techniques. Special contact conditions between the masonry infill and the surround-ing reinforced concrete frame may be accounted for by introducing appropriate interface conditions for the cases of separation, tensionless bond, friction and slip. Publications: [12], [14].
  • Solution to the problem of lubricated flow of oil droplets in capillary tubes using the analog equation method along with the boundary element method. The developed methodology produces a meshless numerical model.

Valavanides of the Civil & Infrastructure Engineering Department of TEI-A.
