Christos Karakostas

Doctorate in the field of Numerical Analysis of Structures using the Finite Element Method (Civil Engineering Dpt., Aristotle University of Thessaloniki, 1989). Consultant Engineer (1984-1995), specialized in the design of special Civil Engineering Structures (industrial facilities, bridges, shell structures) and the construction management of big industrial complexes. Consultant in one of six pilot studies funded by the Earthquake Planning and Protection Organization (EPPO) for the applicability of the New Greek Seismic Code (finally enforced in 1995). Member of the scientific committee set up by EPPO (2000) that proposed the seismic vulnerability assessment methodology for existing buildings that now holds in Greece. Since 1995, Researcher at ITSAK (EPPO-ITSAK after the Aug.2011 merging of the two organizations). Author/co-author of more than 100 papers published in International Scientific Journals or presented at International and National Conferences. Participant in more than 30 Research Programs funded by EPPO, the Greek Directory General for Research and Technology (GGET), and the European Union. Expert evaluator for research proposals for the European Union and GGET. Research interests include: Experimental and analytical investigation of the dynamic behaviour of structures, structural components, materials and non-structural components subjected to earthquake actions; New methods for seismic design and estimation of the seismic capacity of existing buildings (performance-based design methods, pushover and nonlinear dynamic analyses etc.); Development of Finite Elements for the dynamic analysis of shell structures; Development of site-dependent design spectra for Greece; Assessment of seismic risk of urban areas and seismic evaluation of existing buildings; Instrumentation of structures (buildings, bridges, dams) and evaluation of their dynamic response; Development of a low-cost accelerograph for explicit microzonation studies; Development of Stochastic Boundary Elements for the estimation of the propagation of seismic waves in soils with random properties. Consultant in special seismic hazard/vulnerability studies performed at ITSAK for several important Civil Engineering structures (mainly hospital buildings and dams) in Greece.
