Concrete structures with FRP reinforcement
Valent, Matej ; Januš, Ondřej (referee) ; Girgle, František (advisor)
The bachelor thesis deals with the usage of FRP reinforcement in concrete structure designs. The designed structure is a sedimentation reservoir that consists of two prefabricated segments. The construction is classified into the XC4 exposure category. The theoretical part of the thesis provides an overview and explains particular types of FRP reinforcement, their properties, and mechanical durability. We describe GFRP reinforcement and its design for bending and shear, consecutively providing different approaches in a plan for a short-term or long-term carrying capacity. The experimental part of the thesis contains two alternatives. The first application involves B500B reinforcement in both prefabricated segments, while the second part, it is using Schöck ComBAR® reinforcement instead. Moreover, both possibilities and their design take into consideration the ultimate limit state. Subsequently, the obtained results are compared. The experimental part of the thesis includes calculations as well as drawings documentation.

Design of a prestressed concrete bridge on the road I/38
Valent, Matej ; Nováček, Jan (referee) ; Zich, Miloš (advisor)
The diploma thesis deals with the design of an additionally prestressed and horizontally curved bridge structure on the 1st class road. The bridge is located on the newly emerging southeast bypass near the Czech town of Havlíčkův Brod. Three variants of the main supporting structure were proposed, with the choice being a chambered cross-section with inclined side walls. The total span of the bridge, with a length of 273,0m, was divided into 7 spans. The thesis also includes the design of the construction sequence. An assessment of the ultimate limit state and serviceability was carried out. Visualization and drawing documentation have been prepared for the thesis.
