R&D&I

DE develops R&D&I activity in the fields of structural safety, behaviour of structures in the life cycle, in particular the dynamic behaviour of structures and their vulnerability, seismic risk assessment, aerodynamics of structures, risk assessment of physical and biological degradation of wood and other natural materials and characterization of innovative products and construction systems.


The R&D&I strategy adopted by DE, in coherence with the research and innovation strategy (E2I) established by LNEC for the period 2013-2020, answers the request of the Action Plan of this E2I for discussion of the global strategy within LNEC research units. This strategy adopts nine priority research lines and details its contents and previsions of projects and participation of research staff of DE, of other LNEC research units and of external partners.

 

For the period 2013-2020, the strategic lines of R&D&I of DE are:


1. Management of transport infrastructures

  • New technologies for bridge inspection
  • Integration of information obtained in situ in the assessment of structural performance
  • Development of models for the degradation and maintenance of bridges and special structures
  • Life cycle analysis of bridges and special structures

2. Assessment, rehabilitation and structural strengthening
  • Identification and characterization of existing constructions in Portugal in terms of current structural systems
  • Evaluation of structural behaviour and structural typologies
  • Structural strengthening techniques
  • Pre-normative and normative research to support structural rehabilitation


3. Development and optimization of biomaterials for construction

  • Innovation and development of products and processes of wood based materials
  • Construction products with incorporation of bio-waste
  • Integrated pest control in biomaterials in construction


4. Structural systems and innovative products

  • Defining performance requirements for alternative markets
