Our system is currently under heavy load due to increased usage. We're actively working on upgrades to improve performance. Thank you for your patience.
The purpose of monitoring the technical condition of high-rise buildings is to prevent possible negative situations leading to significant socio-economic losses by timely warning of the emergence of such situations. To achieve this goal, it is necessary to solve the following main tasks, such as: identifying the time and place of origin and development of negative processes that lead to the emergence of an emergency situation; analysis of the possible development of the situation in time; development of management decisions; formation and submission of warning signals; obtaining new knowledge about the operation of the object, the factors of influence on this object, the speed of development of destructive processes. When solving the above problems, an important role is played by constructing an adequate mathematical model of the object, the parameters of which should be calibrated according to the current monitoring results.
The report considers the history of development of general theory of vibroacoustic simulation of distribution of broadband dynamic loads on bearing structures of buildings and structures. The following examples show the principles of construction of their direct and inverse vibroacoustic models in series and in parallel. It has been proven that the topology of the original schema is completely the same as that of its inverse model. This makes it possible to conclude that inverse vibroacoustic models of building structures are most convenient for design modeling of complex and multi-connected mechanical oscillatory systems. It is shown that vibration acoustic models for the first time allowed to create algorithms of automated design simulation of explosion resistance of bearing building structures in a wide band of numerous resonances of frequency reaction of the construction structure and its elements to explosive pulse loads.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
