Pedestrian bridge across the river Svitava
Bezručová, Kristína ; Koláček, Jan (referee) ; Nečas, Radim (advisor)
The aim of this thesis is the design and analysis of pedestrian bridge across the river Svitava. Three variants were designed. The variant of one-span frame construction with a parabolic haunch was chosen for analysis. The calculation of load effects was made in software Scie Engineer. For evaluation was used MS Excel. The design and assessment are according to the europien standards. The time dependent analysis is not treated in this work.

Bridge in Lipová Lázně village
Christ, Roman ; Bezručová, Kristína (referee) ; Panáček, Josef (advisor)
The subject of this bachelor thesis is the design of a perpendicular bridge structure across the Staříč River in the village of Lipová Lazne. The bridge translates communication II. class number 369, design category S7,5. Three design variants of the plate bridge are elaborated on a single field. The chosen variant is solved by means of an additional prestressed plate of a rectangular cross-section of height from 1000 mm to 920 mm in width and length of the supporting structure 20850 mm. The static model is solved as a simply supported plate with a bridging length of 18420 mm. The design was executed according to the standard ČSN-EN 1992-2. Calculation of load effects was performed using Scia Engineering 2019 software. Design and design assessments have been carried out according to the applicable regulations and norms.

Pedestrian bridge across the lagoon
Bezručová, Kristína ; Kaláb,, Pavel (referee) ; Nečas, Radim (advisor)
The aim of this thesis is the design and analysis of pedestrian bridge across the lagoon. Three variants were designed. The variant of structure, which combines stress ribbon with steel arches, was chosen for analysis. There is a chapter in this thesis which deals with an ideal shape of arches for different types of loads. The calculation of load effects was made in software Ansys 17.0, considering scnstruction stages. Ultimate limit state and state limit state are evaluated. For evaluation of concrete cross sections was used MS Excel. Steel cross sections were evaluated in software Ansys 17.0. d Dynamic behaviour of construction was assessed. The mode shapes and natural frequencies were calculated. The harmonic excitation response was studied. The loss of stability was checked. The design and assessment are according to the european standards.

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.

Determination of Cable Weakening using Dynamic Measurement
Bezručová, Kristína ; Nečas, Radim
Paper discusses the possibilities of measuring the dynamic response of cables to impulse excitation. Basic relations between cable force and natural frequency of cable and conditions of use on real structures are mentioned. Methods are applied on a pedestrian bridge in Napajedla. The aim of the measurement was to determine the cable force and to evaluate their condition and stress based on the dynamic response.
