Bogachenko S.V. Monitoring of the technical condition of buildings and structures based on information technology. Dissertation for the degree of Doctor of Philosophy in the specialty 192 “Construction and Civil Engineering.” - Ukrainian State University of Science and Technology, Dnipro, 2024.
The dissertation is devoted to improving the process of monitoring the technical condition of buildings and structures through the use of digital technologies.
Modern engineering infrastructure, including buildings and structures, plays a key role in ensuring human comfort and safety. However, despite standards and regulations, the effective organization of repairs, reconstructions, and restorations of buildings and structures, as well as ensuring their safe operation, requires a systematic and innovative approach.
One of the methods that provides initial information for organizing repairs and ensures exploitation safety is monitoring the technical condition of building structures. The main problem in this area is the lack of digital information systems that can be used to store and analyze information on the technical condition of buildings and structures. Existing monitoring methods are generally based on periodic inspections, the results of which are reflected in reports on paper or in scattered electronic documents.
The absence of a digital information system that integrates monitoring data creates gaps in the information base needed for making management decisions. The need for a digital information platform capable of accumulating, systematizing, and visualizing information regarding the technical condition of structures is a pressing issue.
The introduction outlines the relevance of the topic, the purpose of the research, the scientific novelty, the practical significance of the obtained results, the personal contribution of the researcher, and the approbation of the research results.
The first section analyzes existing methods for monitoring the technical condition of building structures and the regulatory and legislative framework of Ukraine related to the inspection and assessment of the technical condition of buildings and structures. The technical condition of building structures can be tracked through structural health monitoring (stationary) or monitoring based on periodic inspections (non-stationary). Structural health monitoring based on the use of automated systems and ensures the collection, processing, and storage of information in real time.
It has been established that monitoring using automated systems allows for prompt responses to changes in building structures. However, it is most appropriate to use these systems in the operation of structurally complex buildings or in buildings with a consequence class of CC3. On the other hand, monitoring based on periodic assessments can cover a larger number of buildings and structures and is a more universal method.
The second section defines the technical operation of buildings and structures as a process of maintaining their exploitation condition, which serves as a basis for creating an information system for monitoring the technical condition of buildings and structures.
In addition, five factors have been identified that contribute to the occurrence of defects and damage: construction defects, design defects, violation or change in operating conditions, impact of the working environment, and impact of the soil base. Additionally, a list of common defects and damages for each factor is provided.
The next step involves examining defects and damages in terms of information and establishing a list of required data, which includes: date of detection or clarification, data on the responsible contractor and the organization that conducted the survey or inspection, description and possible causes of the defect or damage, dimensions (units of measurement, quantitative indicator), location (reference to a map or scheme of defects, axis, row, mark), sketch or photo, structure or element on which the defect or damage was detected, recommendations for stabilizing or eliminating the defect or damage on which the defect or damage was detected; recommendations for stabilizing or eliminating the defect or damage.
To ensure the completeness of the information, it was determined that it was necessary to provide for the possibility of tracking changes in strength and deformation characteristics. After determining the list of required data, the main components of the information system were identified, which include: a database, a database management system, and an application program. The architectural concept of the database was developed taking into account the requirements of the legislation and regulations of Ukraine in the field of construction. The database architecture can be divided into static and dynamic blocks.
