Building survey and evaluating the state construction
Nguyen, Martin ; Komárková, Tereza (referee) ; Heřmánková, Věra (advisor)
This diploma thesis deal with the building survey and evaluating the state of existing constructions. In theoretical part are described the types of civil engineering surveys and diagnostic methods for conducting a survey of reinforced concrete structures. The practical part deal with describes the structural and technical survey of the production hall in the industrial area Fatra Napajedla, evaluating the strength of concrete on the existing structure through donations cores and verification of compliance with the reinforcement according to project documentation. The last part is focused on a static assessment of selected supporting elements of the structure.
Survey and evaluation of building constructions
Balas, Ondřej ; Komárková, Tereza (referee) ; Heřmánková, Věra (advisor)
This thesis is focused on the description and evaluation of the status of existing reinforced concrete and of the prefabricated overhanging structures. The first part describes the solution overhanging structures, followed by a description of selected diagnostic methods for determining the properties of concrete in the structure and to determine the degree and extent concrete reinforcement. The main objective is to determine the status of overhanging structures on the case static analysis and critical points of the support structure for the purpose of the planned revitalization of the object.
Use of ultrasound testing of concrete in bridge structures
Olejková, Sabina ; Komárková, Tereza (referee) ; Cikrle, Petr (advisor)
There are analyze kinds of diagnostic methods in terms of bachelor’s thesis. It is written about principles of ultrasonic pulse method and its options of usage on the current concrete structure. There are processed results of measurement on the testing samples which will be compared with results of stress strength. There is also spoken about calibration relationships in the bachelor’s thesis. Calibration relationships are described in Czech technical norms.
The verification of durability of surface layer by pull-off testing
Fujačková, Hedvika ; Komárková, Tereza (referee) ; Kocáb, Dalibor (advisor)
The theoretical part of this bachelor's thesis defines the basic properties, categorization, and use of the individual components of concrete and presents the properties of fresh and hardened concrete, especially the tensile strength. Furthermore, the thesis addresses the problem of durability assessment of concrete, which depends directly on the quality of the surface layer. The experimental part of the thesis focuses on executing of a pull-off test and examines the surface layer tensile strengths of various concrete mix designs. The thesis examines how the results of the measurements correspond with other published results.
Diagnostics of prestressed bridge structures
Konderla, Jiří ; Komárková, Tereza (referee) ; Láník, Jaromír (advisor)
The theoretical part of this bachelor thesis focuses on prestressed concrete and problems that are nowadays showing with using prestressed concrete in bridge engineering and on the methods that are used for condition check of this material. Practical part of the thesis is the construction research and diagnostic of the prestressed concrete bridge structure, evaluation and consecutive interpretation of used methods.
Diagnostics and assessment of the structure of bridge
Lehocký, Peter ; Komárková, Tereza (referee) ; Kocáb, Dalibor (advisor)
This diploma thesis focuses on diagnostics of bridge structures. First part of this diploma thesis will focus on theoretical knowledge about bridge structures and common diagnostic techniques suited for examining material priperties of samples taken from structure. Second part of this thesis will focus on practical use of experiments used in diagnostic branch. I will be doing visual observation of concrete structure followed by experiments on core samples. End of thesis will be evaluating structure from global perspective and will deliver specific sugestions for renovation.
Experimental determination of the relationship between NDT parameters and the compressive strength of concrete
Kozáček, Vojtěch ; Komárková, Tereza (referee) ; Kocáb, Dalibor (advisor)
The diploma thesis deals with non-destructive testing of concrete as well as with the relationship between determined parameters and the compressive strength of concrete. The thesis is mainly focused on the ultrasonic pulse velocity method and the rebound hammer test. The experimental part of the thesis describes non-destructive tests performed on concrete blocks. The compressive strength was tested on the drill cores taken from the concrete blocks. The aim of this thesis is to find regression models of the relationship between the compressive strength and non-destructive parameters, and the subsequent analysis of the results.
NDT control of anchors built in concrete
Komárková, Tereza ; Šašek,, Ladislav (referee) ; Pošvářová, Miloslava (advisor)
Non-destructive inspection using ultrasonic anchoring method is the only possible way to detect inadequate anchorage length. For rescue roads systems inadequate anchoring can have fatal consequences. Therefore, control anchoring bridge barriers should be carried out every installation of crash barriers.
The possibility of application of basalt reinforcement in lightweight concrete
Jarnot, Martin ; Komárková, Tereza (referee) ; Schmid, Pavel (advisor)
This diploma thesis deals with the application of basalt reinforcement in lightweight concretes. In the practical part, the comparison of steel and basalt reinforcement in concrete from agloporite and steel reinforcement in concrete from Liapor is performed experimentally.
The influence of the change of moisture content of timber on its physical-mechanical properties
Novák, Jakub ; Komárková, Tereza (referee) ; Heřmánková, Věra (advisor)
This bachelor thesis deals with the physical and mechanical properties of spruce wood at different humidity and verifies the individual properties, depending on the humidity of the wood. The theoretical part of this work is focused on the description and characteristics of the general characteristics and structure of wood. The practical part deals with the testing and measuring of wood samples at different moisture and evaluate the physical and mechanical properties. Finally, static calculation verifies difference resistance of structural members stressed bend at different humidities.
