FIELD: construction.
SUBSTANCE: method consists in creation of computer model of structure, model of loads and actions at it, calculation of characteristics of bearing structures to form matrix of border values of these characteristics and definition of categories of building state and indices of variation of condition of bearing structures and points of bearing structures, which are critical for safety of structure. At the same time measurements are carried out with the help of sensors installed in critical points, integral characteristics of bearing structures, data of sensors is collected and processed, and measured integral characteristics are compared with elements of matrix of border values of these characteristics. Results of comparison are used to categorise condition of structure, and means of display are used to display information on current category of structure condition, in case critical deterioration of structure bearing elements safety condition occurs, information is transmitted to users along communication channels. At the same time periodical inspection and tuning of system are carried out with the help of continuous loading unit installed in critical point and producing signal of loading and polling of system sensors, and produced information is processed. As values of integral characteristics of bearing elements change, matrix of border values of integral characteristics of building/structure state is corrected. System comprises at least one loading unit of continuous action, producing loading signal of intentionally specified form and/or frequency, unit of determination of own frequencies of oscillations, unit of measurement of accelerations of oscillations, unit of measurement of oscillations amplitudes, unit of measurement of oscillations speeds, unit of measurement of inclinations, unit of flexures measurement, unit of stresses measurement, unit of measurement of loads, unit of measurement of absolute and uneven subsidence, unit of measurement of geodesic parameters, unit of processing and output information, unit of output information grading intended to categorise level of safety of building/structure, unit of measurement of ground waters measurement, unit of moisture measurement, unit of moisture metres, unit of temperature measurement, unit of information transfer to consumers, at least one source of uninterrupted power supply and unit of inbuilt monitoring of system and its elements serviceability, besides, all specified units are connected to buses of data transfer, control buses and supply buses.
EFFECT: increased certainty of warning to public on possibility of emergency situations in buildings, structures, and their prevention due to timely detection, annunciation and response.
