Special Sessions

Strengthening, Monitoring and Life-cycle Assessment of Metallic Structures
organised by Dr. Elyas Ghafoori from Empa, Switzerland

There are a large number of metallic structures, such as railway and highway bridges, off-shore structures, pipelines, communication towers and mining equipment, which are aging because of fatigue and corrosion damages. The increasing service loads and harsh environmental conditions make these structures even more vulnerable. On the other hand, although methods for the strengthening of concrete structures have been already well developed and used in many practical cases, this is not the case for metallic structures. There is clearly a need for studies that aim to develop feasible retrofitting methods, along with design approaches, for the strengthening of metallic members.

This special session will share new research results on static and fatigue strengthening of metallic structures using traditional or advanced materials and will provide a platform for researchers to discuss and compare their research results and to enhance future collaboration in this topic. Furthermore, this special session covers the following topics and also other related topics:

  • Assessment, management and strengthening techniques for existing metallic bridges
  • Retrofit solutions using CFRP materials (e.g., bond behaviour, pre-stressing methods)
  • Rehabilitation and monitoring of steel-concrete composite structures
  • Structural health monitoring (SHM) of steel bridges
  • Experimental, numerical and analytical studies on static and fatigue assessments of critical details (e.g., welded and riveted details) in metallic structures.
