Abstract
Introduction. A separate category includes river-bed pressure buildings of hydroelectric power plants. Such buildings include reinforced concrete piers, beams, pressure walls together with the floors of machine rooms, foundation slabs, etc. At the same time, as an integral element, they have inter-block construction joints. During the long-term operation, problems arise, which lead to a decrease in the operational characteristics of reinforced concrete structures of hydroelectric power plant buildings.
Materials and methods. The reinforced concrete structure of the Tishrin hydroelectric power plant’s channel pressure building was modelled using the finite element method to determine the stress-strain state under the influence of an earthquake with an intensity of more than 8 points. The corresponding calculations were performed based on dynamic theory using accelerograms.
Results. The calculations of the stress-strain state of the reinforced concrete channel pressure building of the Tishrin hydroelectric power plant showed that the opening of the inter-block construction joints, the contact joint between the base of the hydroelectric power plant building and the foundation, and the formation of cracks in the monolithic part occur under the influence of tensile stresses.
Conclusions. Based on the results of the calculations, it was necessary to reinforce the reinforced concrete structures of the Tishrin hydroelectric power plant, for example, by using pre-stressed composite reinforcement.
