Naumov V. Justification of methods of dismantling structures of buildings and structures. – Qualification scientific work as a manuscript. Dissertation for the degree of Doctor of Philosophy in the specialty 192 – Construction and civil engineering, field of knowledge 19 – Architecture and construction. – Ukrainian State University of Science and Technologies, Dnipro, 2024. Main content of the dissertation The dissertation is aimed at improving the methods of selecting demolition technologies for buildings and structures. The research goal is to use intelligent technologies for optimal selection of demolition scenarios. The study aims to develop software that will allow quickly and efficiently selecting the most suitable demolition strategies under conditions of building damage or aging. The use of such software will help optimize the demolition processes, ensuring a high level of safety. Based on the results of the research and analysis of the obtained data, the dissertation is devoted to the development of a comprehensive methodology for studying and optimizing the processes of demolition of buildings and structures. The main conclusions obtained as a result of the research include the following: • Systematization of technological solutions: The conducted analysis allowed to systematize technological solutions and their documentation, which will contribute to avoiding mistakes and improving the efficiency of project implementation. • Use of digital technologies: The application of digital technologies in the development of technological documentation allows significantly optimizing the process and reducing time and resource costs. • Normalization of technological processes: Developed approaches to typification and normalization of demolition technological processes will contribute to the standardization of work and increased safety of the process. • Development of Software: The developed program for the analysis and planning of building and structure demolition integrates key components, enabling rapid and accurate optimization of technology and equipment selection. The research results demonstrate the significance of a comprehensive approach to analyzing and optimizing building and structure demolition processes, contributing to increased efficiency and safety in the construction industry. From the perspective of the philosophy of science, the dissertation aims to address the pressing philosophical issue regarding the values and principles guiding demolition work in construction. Modern methodology examining dynamic dependencies and interactions among various factors affecting the demolition process is employed within the research framework. Key characteristics of this methodology, vital for the study, include the following: considering various phenomena and processes in construction as complex and interdependent; regarding factors influencing demolition work as dynamic and time-varying. The first section is dedicated to a detailed analysis of contemporary technologies, methods, and factors related to building and structure demolition processes. Preconditions prompting demolition work execution in Ukraine are explored, considering the specificity of modern construction and sustainable development requirements. An analysis of national and international methods for assessing the seismic resistance of structures, particularly in the context of European standards (Eurocodes), allows identification of key aspects affecting nuclear power plant safety. Additionally, modern approaches to building and structure demolition project development, particularly in the context of using integrated approaches to enhance efficiency and minimize adverse environmental impacts, are examined. An overview of contemporary research on innovative methods and adaptations for demolition work execution is provided, including an analysis of technological solutions and waste management methods in construction and demolition. Key directions for further development in this field are identified, including the development of demolition feasibility assessment methodologies, studying the impact of various demolition methods on material and resource preservation, and considering technical and economic aspects of implementing advanced technologies such as Building Information Modeling (BIM) in demolition planning and execution. The overall conclusion of the chapter underscores the importance of actively implementing innovative approaches in the field of building and structure demolition to enhance process efficiency and ensure sustainable development of the construction industry.
