New opportunities for the use of concrete structures sustainability assessment tools for a forensic engineering
Hrabová, Kristýna ; Kuda,, František (referee) ; Prostějovská,, Zita (referee) ; Vymazal, Tomáš (advisor)
In recent years, the European Union has been working to revise its climate, energy, and transport legislation to align existing legislation with the goals set for 2030 and 2050. These ambitions are closely related to the principles of sustainability. A growing population places increasing demands on the environment. Thus, improving living standards without damaging the environment is becoming a global challenge. The construction industry is an important segment of the world economy and contributes to environmental pollution. The concrete industry can also be counted among the main producers of CO2 emissions. The future of concrete construction design will be linked to new but also ongoing transformations of our society. The rapidity, speed, and frequency of the changes that are being implemented will also create a new urgency for knowledge and methodology in this field, whether for concrete producers, designers, or forensic experts. The focus of this thesis is the need to respond to new requirements in the field of concrete structures. In June 2016, the fib board approved activities to start working on the development of an updated fib Model Code 2020 (MC2020). This Model Code 2020 will form the source of new versions of the relevant Eurocodes and ISO standards, with sustainability as a fundamental requirement. Therefore, the design of a structure will now have to take into account not only durability considerations but also performance and overall environmental impact. Therefore, the dissertation focuses on the analysis of new trends in concrete structures to categorize the areas of change that may occur. The thesis deepens understanding of the areas of change as well as the methods of evaluation of building materials and concrete structures. Based on the identified shortcomings of the methods to assess the sustainability of materials, a sustainability indicator for CSB has been proposed. The changes brought about by the new fib Model Code 2020, whether in terms of performance-based design, use of recycled materials, or optimization of structures, may lead to defects and failures in building structures and new types of legal dispute for which there are no algorithms for resolution. In this paper, modern devices used for defectoscopy of defects and failure of concrete structures are also described.
