Diagnostics of bridge structure
Nápravník, Petr ; Žítt, Petr (referee) ; Láník, Jaromír (advisor)
This bachelor´s thesis deals with construction-technical survey of a highway bridge no. D1-243 across Ripska street at suburbs of Brno. Theoretical part contains bridge terminology, inspections, problematics of prefabricated beams I-73, construction-technical survey and description of laboratory tests. Practical part deals with making of a construction-technical survey, evaluation of construction parts and a summary of results.
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.
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.
Diagnostics in the case of evaluating of current state of a building
Kopec, Jan ; Láník, Jaromír (referee) ; Schmid, Pavel (advisor)
This work deals in the theoretical part in its theoretical part with a summary and detailed description of selected diagnostic methods that were applied to selected structural parts of an existing bridge structure within the practical part. The thesis also deals with the basic terminology and terminology in the field of bridge construction, subsequently, in its practical part deals in terms of diagnostics, the implementation of structural and static survey and subsequent evaluation of the current structural, technical and static state on selected structural units of existing reinforced concrete bridge structures
Diagnostics of selected bridge structure
Jedlička, Lukáš ; Láník, Jaromír (referee) ; Žítt, Petr (advisor)
This thesis deals with building survey of bridge register number 43-011 located near Česká. The part of thesis is literary reaserch dealing with system of management and cotrol of road bridges, precast bridge contructions made with DS-C type girgers and about general diagnostical methods. The practical section contains of in situ diagnostical survey and bridge inspection, laboratory evaluation and comparision, load bearing capacity calculation and suggestion of potencional technical precautions.
Evaluation of a historically valuable reinforced concrete structure
Uchytilová, Jitka ; Láník, Jaromír (referee) ; Cikrle, Petr (advisor)
In the theoretical chapters of the bachelor thesis is summary of the historical development of reinforced concrete construction, including individual components of concrete. Furthermore, the issue of the evaluation of historically valuable structures and used diagnostic methods is processed. In the practical chapter there is a diagnostic survey of the selected historical structure including the conceptual design of rescue.
Diagnosis of defects of an existing object
Niedoba, Jakub ; Láník, Jaromír (referee) ; Schmid, Pavel (advisor)
This bachelor thesis deals with structural and technical research of the Lužánky Leisure Time Activity Centre, a civic amenity building situated in Brno, 50 Lidická Street. A building diagnosis was carried out due to a number of static defects spreading fast all over the structure. The first part of the thesis describes the history of the surrounding Lužánky Park. Furthermore, the history of the city’s watercourses and the related issue of clay soil are also discussed. The practical part focuses on the diagnostics of the building together with its current state. After the theoretical assessment, short-term as well as long-term maintenance measures are proposed.
Diagnosis of the fire damaged bridge
Hüblová, Sabina ; Láník, Jaromír (referee) ; Cikrle, Petr (advisor)
This thesis is about assessment of a bridge construction influenced by fire accident. The bridge is situated at the highway D46 beyond the town Držovice. Within this construction research, there will be mentioned diagnostic methods – A non- destructive method (Ultrasonic pulse method and hardness tests) and destructive methods (borehole and tear off tests). For find out in which way was the concrete of the bridge damaged and hurt while facing a high temperature of fire, there were taken samples, which were analyzed by physical and chemical test. We can analyze composition and microstructure of the concrete. The result of this tests will be evaluated, and the actions of a remediation will be suggested.
Diagnosis selected bridge structure
Novák, Jakub ; Láník, Jaromír (referee) ; Žítt, Petr (advisor)
The Diploma thesis deals with the Diagnostics of Reinforced Concrete Bridge in the village of Luhačovice. This thesis also describes the individual Diagnostic methods and instruments used in purpose to make Diagnosis of bridge constructions. The main aim of the Diagnostics is to determine the current state of the Bridge which consists in verification of the actual road structure, determination of the physical and mechanical parameters of the Concrete (strength, depth of carbonation) and in some parts of the bridge structure to determine the type, number and position of the bending or shear reinforcement. Based on the evaluation of the laboratory tests a static calculation of the selected part of the Bridge structure is performed. The final evaluation is the determination of the load and the subsequent design of the necessary and recommended measures for maintaining or improving the functionality of the bridge structure.
Diagnostics and assessment of prefabricated reinforced concrete structures
Kocuba, Robert ; Láník, Jaromír (referee) ; Cikrle, Petr (advisor)
This thesis deals with inspection and constructionally technical research of reinforced concrete prefabricated construction from the second half of 20th century. In theoretical part, the research of literature, documents and valid standards is performed, with a focus on production and construction of prefabricated elements and also on the metodology of research. In practical part, the detection of reinforcement of individual elements of the construction and concrete properties is performed. The result of this work is the assessment of the state of the construction, static calculation of the ceiling panel and idea proposal for eventual reconstruction.
