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.

Modelling, Assessment and Monitoring of Engineering Structures - research carried out at TU Berlin and their partner institutions
organised by Prof. Yuri Petryna from Technical University Berlin, Germany

Engineering structures usually have a long expected service life, a high level of safety requirements and a huge importance for future sustainability. On the other side, they are critical component of the modern infrastructure due to aging and deterioration effects as well as multiple hazards like earthquakes, collisions or incidents. The structures can fulfill those reliability requirements only by use of structural health monitoring.

This Special Session will serve as an exchange platform for researches and practitioners dealing with the following topics:

  • concepts and technologies for structural health monitoring,
  • computational modelling and structural failure analys
  • load measurement and state assessment of existing structures,
  • damage detection, localization and assessment,
  • uncertainty quantification and decision making for SHM,
  • data acquisition and assimilation in the framework of SHM,
  • case studies on various structures like bridges, dams, tunnels, wind turbines, etc.
