Abstract

This diploma thesis is focused on finding out and evaluating the actual condition of a specific bridge structure (detection of defects and faults), which is located in the village Bystřice. The diploma thesis follows up on the already gained theoretical and practical knowledge presented in the author's bachelor's thesis, which dealt with the issue of prefabricated beams used in the second half of the last century. Based on the findings in the bachelor's thesis and the diagnostics of the bridge object in the submitted diploma thesis, a variant solution of the possibility of replacing the existing bridge object is performed. The variant solution is optimized on the basis of factors influencing the design of a new bridge structure (local conditions, type of structure, method of construction etc.). The theoretical construction procedure, including the assembly of the supporting structure, is performed for the selected replacement variant. The theoretical analysis is supplemented by static calculations of both the existing bridge structure and the main parts of the load-bearing structure (attachment 1-3).
