The bridge slab fabricated from precast beams
Surovcová, Monika ; Panáček, Josef (referee) ; Klusáček, Ladislav (advisor)
The thesis deals with a deformability and a load capacity of an existent bridge. A deflection of the real structure was compared with a mathematical model. According to results, following from the composed model, the flexural axis of the orthotropic plate corresponds with real measured values. The numerical equality was attained on the basis of sectional components. Furthermore, a load capacity was determined according to standard vehicles.

Survey and assessment of reinforced concrete bridge construction
Šnédar, Jaroslav ; Láník, Jaromír (referee) ; Cikrle, Petr (advisor)
The aim of this thesis is to evaluate the real condition of reinforced concrete beam bridge located in Brno Jundrov. In order to evaluate this condition, there was made the main bridge inspection. Subsequently, a number of diagnostic methods were used, such as hardness tests, concrete stress strenght, ultrasonic pulse method, including their evaluation. In terms of the main inspection, the condition of construction of the bridge was evaluated as V - bad. We found out that the concrete from which the bridge is built of is in very good condition. The problem, however, is the condition of the reinforcement located on the bridge. Based on its condition there must be expected lifespan within the next 5-10 years.

Analysis of the existing bridge structure
Dvořáková, Lucie ; Olšák, Martin (referee) ; Svoboda, Adam (advisor)
The bachelor thesis deals with the analysis of the existing bridge structure and the subsequent determination of its load capacity according to the limit states of serviceability and load capacity. The bridge on the H1 circuit over the V1 branch has a main superstructure consisting of IS-73 prestressed beams and was built in 1993. The calculation was grasped in two ways, namely by manual calculation on a single IS-73 beam or by converting it to an orthotropic slab.

Bridge construction diagnostics
Konderla, Jiří ; Komárková, Tereza (referee) ; Láník, Jaromír (advisor)
The theoretical part of this thesis is dedicated to bridge constructions in Czech Republic, reinforced concrete and its history of use, examinations of bridges and bridge structures in general. Practical part is focused on evaluation of structural survey of a real bridge construction with a proposal of possible remediation. The calculation part cointain of 3D model of construction and static calculation to determine the maximal capabiality to transfer load from traffic.
