DETERMINATION OF BEARING CAPACITY AND CALCULATION OF THE GAIN OF THE DAMAGED SPAN OF A RAILWAY OVERPASS BY THE FINITE ELEMENT METHOD

English abstract

The subject of the study the possibility of applying the finite element method to determine the bearing capacity of a damaged reinforced concrete structure and the subsequent selection of its reinforcement parameters with composite materials. Research methodology – the studying of finite element models of the servicea-ble destroyed and restored structure and determination of design parameters of the structure before destruction, after the destruction, and after its strengthening. The goal – identification of the possibility of further operation of the damaged structure using the finite element method, finding the most dangerous places in the construction, selection of parameters for its amplification. Conclusion of the study. The proposed research method made it possible to more accurately and at a lower cost, identify the most dangerous areas in the dam-aged structure, and verify the effectiveness of the applied method of its restoration. The method showed high efficiency in assessing the bearing capacity of a structure with complex reinforcement in which part of the reinforcement is in a destroyed state.
