Steel Structures & Corrosion Protection

Section B2, 'Steel Structures and Corrosion Protection', carries out research on hydraulic steel structures and their equipment as well as on steel and composite bridges. The work is also supported by its own chemical and corrosion protection laboratory.

The main terms of reference in the field of steel structures are:

  • issues of as-is state expertises and estimation of remaining service life
  • design of concepts for maintenance and strengthening
  • structural analyses
  • material analyses on metallic substances (chemical, mechanical and metallographical analyses)
  • consultancy services for replacement and new structures with regard to the selection of systems and materials, including fatigue-proof and corrosion-resistant designs
  • research and development activities for practical application and implementation in standards

Corrosion protection concepts and systems are made available for corrosion protection of (hydraulic) steel structures (sheet piling, gates and valves, steel bridges) and floating vehicles:

  • Principally a combination of (passive) coating and (active) electro-chemical protection is recommended for hydraulic steel engineering.
  • On the basis of BAW Guidelines and Codes of Practice, suitability tests for protection systems are carried out in the corrosion protection laboratory and a list of coating systems with relevance to practice will be issued.
  • Consultancy services for the repair of damages at existing coating-systems concerning implementation and selection of material.

The chemical laboratory supports these tasks using modern analytical methods. The methods for determination (apparative analysis, microscopy, corrosion measurement cell) are used to assess researches of corrosion damages as well for the testing of construction and other materials.
