Cable-supported bridge
Kovářová, Marika ; Bezručová, Kristína (referee) ; Nečas, Radim (advisor)
The theme of the thesis is to design a pedestrian bridge over a river. Out of two possible designs, the cable-stayed construction was chosen. The deck of the bridge is designed as a monolithic construction supported by cables from two inclined pylons. Two models were developed for the calculation of internal forces: a strut model for the longitudinal direction and a plate model for the perpendicular direction. These calculations were checked up by Finite Element Method (FEM) in SCIA Engineer 2017 software. Considerable part of the thesis was dedicated to the creation of so-called initial state. The design of the prestressing force and the evaluation of ultimate limit state and serviceability limit state was made in accordance with the codes currently in force. Small part of the theses is dedicated to the verification of the load bearing capacity of the pylon on the combination of normal force and bending moment with a subsequent verification in the software IDEA StatiCa9. The pedestrian bridge of 64,150 m length is considered as a perpendicular.

Lhota Rapotina bypass - location study
Kovářová, Marika ; Efenberk, Tomáš (referee) ; Radimský, Michal (advisor)
The subject of the diploma thesis is the design of the bypass of the village Lhota Rapotina, road II/374, processed in the details of the study. The village of Lhota Rapotina is located in the Blansko district in the South Moravian Region. The task of the diploma thesis was to examine possible alternative solutions of the bypass with connection to the existing and planned surrounding infrastructure related to the construction of the Boskovice – connecting road. The aim was, among others, to propose a solution that would reduce the traffic intensity in the village (especially the high number of trucks transporting material from the adjacent quarry). Three variants of the bypass were developed; eastern and western. From the developed variants, the western bypass variant designed in the S9.5/90 category was selected for closer examination, which respects the location of the planned Boskovice - connecting road and which also serves as a flood protection measure for the village.
