Abstract
The aim of the dissertation work is to create a new information technology for diagnosing the current state of multi-story building to eliminate its over-normative roll while simultaneously ensuring the reliable functioning of the multi-story building during the entire process of leveling without stopping the functioning of the multi-story building engineering networks, technological equipment (elevators) and the resettlement of residents, which will allow to improve the quality of estimates of the forecast of changes in the multi-story building vehicle in the controlled elimination of excessive tilting and to make responsible management decisions in conditions of uncertainty and the risk of construction accidents. Information technology for diagnosing the current state of multi-story building was developed for the first time to eliminate the tilting of the building in conditions of constant changes in its vertical position, the physical and mechanical properties of the foundation soils and the properties of the materials of individual building structures (cracking) during the entire time of leveling without stopping the operation of the engineering networks of the multi-story building, technological equipment (elevators) and the resettlement of residents, and sometime after its completion; the specialized Pendulum program for operational processing in online mode of experimental data from pre-trial inclinometric sensors distributed over the multi-story building (Digital Twins elements) in the process of eliminating its excessive roll, and graphical interpretation of the results for a better perception of information technology for diagnosing the current state of multi-story building information and is an element of feedback when support of operational management decisions in the process of liquidation of the above-standard bank roll. The mathematical-algorithmic apparatus of information technology for diagnosing the current state of multi-story building has been improved, which includes mathematical models of buildings and foundation soils that were used in the process of leveling the multi-story building, a mathematical model of drilling mixtures for fixing the foundations of the building after the leveling process is completed; precision sensitive inclinometric elements, a special stand has been developed for their testing and metrological research; continuous connection between the measurement results of the pre-screen sensitive inclinometric elements distributed over the multi-story building and the LIRA application program package for operational consideration of the change of the initial boundary conditions during the current calculations of the stressed - deformed state of the multi-story building during the entire alignment process and sometime after its completion. The system for transmitting digital experimental data from precision inclinometric sensors distributed over the multi-story building, with the help of modern cloud technologies (Internet of Things elements), received further development.
