Research

Research and expert activities of the department are focused on the soil mechanics, concrete and steel transport structures, diagnostics of road and railway structures.

JPTF is a member of the National Technology Platform Interoperability of the Railway Infrastructure and National Technology Platform for Road Transport.

 
Research is being conducted within the framework of projects and programmes of:
  • Development programmes of the University Development Fund (FRVŠ),
  • Development programmes of the Czech Science Foundation (GAČR),
  • Development programmes of the Czech Ministry of Education, Youth and Sports (MŠMT),
  • Other projects.

Research and Development Activities

Organization and thematic structure of R&D at the Department of Transport Structures is shaped especially by specialization in particular expert areas of the department. Those are:
  • Bridge structures (concrete and steel),
  • Roads,
  • Railways,
  • Geotechnical structures (slope stability, foundation structures, underground structures).
Contemporary trends of research and development, given by thematic research priority areas in the European Research Area (ERA) and National Policy of Research and Development in the Czech Republic, tend to deal with research projects and grant opportunities in collaboration of more departments. External collaboration is performed with other universities, institutes of Czech Academy of Sciences, departmental institutes and foreign institutions.
The common feature of fundamental trends of R&D pursued at the Department of Transport Structures is the specialization in diagnosis of main transport structures, area of development of new materials, structures and technologies with respect to their durability and reliability, dynamic stresses during their lifetime, etc.
Research activity is realized within scope of research projects supported by grants of Czech Grant Agency, Czech Academy of Sciences and Czech Technological Agency, national authorities, particular ministries, European Union or construction companies. Thanks to 7th Framework Programme of the European Union, COST, Erasmus+ and other projects, there is a direct international collaboration at the department.
Judicial expert activities which are focused on defects of the transport structures in the Czech Republic are also emphasized.
