Abstract

This bachelor's thesis presents the design and detailed structural analysis of a soil-covered reinforced concrete frame bridge. The structure serves as a grade-separated crossing for road routes within the planned bypass of the town of Rychnov nad Kněžnou. Based on the boundary conditions and the identified load-bearing bedrock, the concept of a rigid frame on spread foundations is selected. A shell-element computational model of the structure and the analysis of internal forces are created in the Midas Civil NX software, while the soil-structure interaction is modeled using the GEO5 program. In the core part of the thesis, the critical cross-sections of the frame beam and vertical walls are dimensioned and structurally assessed in terms of ultimate and serviceability limit states according to current European standards. The result of the entire procedure is the reinforcement design, which demonstrates the safety and reliability of the assessed structure.
