Design of a one-span railway bridge
Tomisová, Gabriela ; Panáček, Josef (referee) ; Nečas, Radim (advisor)
The topic of this thesis is a design of an one-span bridge over a river, a bicycle path and a route for pedestrians. The construction of prestressed beam bridge with one field with lower bridge deck is preferred out of all developed options. The construction is designed and assessed to the ultimate limit state and the serviceability limit state according to actual EN standards.

Survey and Diagnostics of Building Construction
Řezáč, David ; Komárková, Tereza (referee) ; Anton, Ondřej (advisor)
The subject of this bachelor thesis is the construction research and diagnostics of the construction with the focus on the verification of the prestressing reinforcement of the prefabricated prestressed bridge. The theoretical part of the thesis focuses on reinforced concrete, prestressed concrete, their properties and determination of these properties by means of instruments of selected non-destructive, semi-destructive and destructive methods. In connection with the theoretical part, the most suitable methods were used to verify the position of prestressing reinforcement, which means using the Hilti PS1000 georadar and the electromagnetic indicator Profometr PM-630.

Application of GPR method for detection of structural failures
Křepelka, Jan ; Láník, Jaromír (referee) ; Cikrle, Petr (advisor)
This Bachelor thesis deals with the non-destructive testing, which enable researches of failures in concrete inner structure. In the theoretical part of the thesis, selected methods are described based on their principles. Specific possibilities of use, abilities and limits are based on the method’s principle. In the practical part, the thesis focuses on Ground Penetrating Radar with the usage of a new multi-frequency scanning technology. The measurements took place with commonly used Ground Penetrating Radar Hilti PS 1000 X Scan and also with newly available Ground Penetrating Radar Proceq GPR Live. Not only the measurement results of model solids were compared, but also of real bridge construction.

Time requirements of construction of a building object
Procházka, Jan ; Výskala, Miloslav (referee) ; Aigel, Petr (advisor)
The topic of this bachelor thesis is Time requirements of building construction. The aim of this work is to analyze the time consuming construction of the building. The work is focused on reinforced concrete bridge frame structures. The first part describes the technology of construction and structural types of bridges. The second part of the thesis deals with the determination of the construction time indicators. The individual indicators are related to the area and volume of the bridge structure, and the pace of construction of the individual parts of the bridge is analyzed.

Design of a railway frame bridge
Findura, David ; Brtáň, Stanislav (referee) ; Nečas, Radim (advisor)
This thesis deals with a design of a two-track railway frame bridge over a valley. Out of three proposed variants was chosen the variant number 1 - prestressed frame construction with variable beam section. According to actual EN standards the construction was designed and assessed to the serviceability limit state and the ultimate limit state.

Design of a one-span bridge over a local brook
Haluška, Ľuboš ; Koláček, Jan (referee) ; Nečas, Radim (advisor)
The aim of this thesis is the design and analsysis of a one-span bridge over a local brook. Two variants were designed. The variant of one-span prestressed beam bridge with lower bridge desk was chosen for analysis. The calculation of load effect was made in software Scia Engineer. The supporting structure is assessed for the ultimate limit state and the serviceability limit state according to the europien standards. The time dependent analysis is not trated in this thesis.

Diagnostic investigation of bridge construction
Houška, Radek ; Láník, Jaromír (referee) ; Schmid, Pavel (advisor)
This master thesis refers to implementation exhaustive research of bridge construction. This diagnostics research serves as the first step of objective assessment of the condition of the bridge for further processing of investor intent. In the next two steps was the research focused on detailed research of the substructure for decide of the volume of the reconstruction and on the real condition of the superstructure for the check of the load capacity of the bridge.
