Abstract
The purpose of the work is to carry out surveys to determine the actual state of thermal power plants located in areas with high seismic activity on the basis of comprehensive instrumental surveys and computational studies. The authors present an approach to the assessment of long-term operated thermal power plants in the zone of increased seismic activity. Over the period of long-term operation, the building structures have undergone changes in comparison with the design prerequisites, while the current regulatory documents contain instructions for the use of an increase in the calculated seismicity by 1‑2 points relative to the design data of the 60‑70 years. The article provides recommendations for drawing up a program for visual inspection of metal and reinforced concrete structures, as well as comprehensive instrumental surveys Thus, the thermal power plants built 45‑60 years ago and currently in operation are experiencing a lack of reliability during high-intensity seismic events. The article provides recommendations for drawing up a program of visual inspection of metal and reinforced concrete structures, as well as comprehensive instrumental surveys. Recommendations for drawing up a program for visual inspection of metal and reinforced concrete structures, as well as comprehensive instrumental surveys are presented. Proposals are given for the development of finite element models of structures for assessing seismic resistance to the effects of a design and control earthquake.
