Combining the methods of periodic and continuous monitoring of the facility provides expanded information about the technical condition of the facility, virtually eliminating emergency situations, timely informing about the occurrence of non-standard situations at the facility during the period of continuous monitoring.
Periodic monitoring is necessary in the prompt, rapid determination of the general technical condition of the study object at the time of the survey, identification of the most problematic and vulnerable areas in the spatial structural model of the study object.
Specialists, in the course of research, on the basis of the promptly obtained results of periodic monitoring, draw up a scheme for the arrangement of a permanent autonomous system of observation points equipped with digital converters of analog signals into digital and low-frequency seismic sensors that register standing waves which determine changes in conditions of uninterrupted autonomous operation during the entire monitoring period.Комплекс предназначен для мониторинга собственных частот колебаний мостов, зданий и любых инженерных сооружений, а также для определения уровня колебаний сооружения в установленных постоянных точках наблюдения. \
Комплекс, предназначенный для мониторинга собственных частот зданий и сооружений, позволяет (рис.1.):
The equipment designed for monitoring the natural frequencies of buildings and structures allows (Fig. 1.):
Determine the main static and dynamic characteristics of the structure of the structure;
Identify resonant negative processes occurring in the structure;
Determine the spatial distribution of the Poisson's ratio (the ratio of transverse deformation to longitudinal deformation allows one to estimate the level of waterlogging of media including the bases of study objects (Fig. 2);
Determine the amplitude distribution maps of the modes of transverse, longitudinal and vertical oscillations in the X, Y and Z directions of the entire structure and constantly monitor the dynamics of changes in the received parameters (the report is provided once a month and in the event of a critical situation, notification via SMS notifications automatically occurs (an example of such an amplitude distribution is shown in Fig. 3)
