The basic diagnostics of an existing building structure
Tomanová, Jana ; Láník, Jaromír (referee) ; Schmid, Pavel (advisor)
This bachelor work deals with the issue of building from the unburnt clay and the trial methods, which are used during the diagnostic of constructions made from clay bricks. The introductory part concerns with the history of the unburnt clay and the development of the unburnt bricks. Subsequently the technology of production in the past and in the present is explained. The use of constructional methods relates to this technology. Furthermore the methods used during the diagnostic of clay constructions are described. In the second part the drawing documentation is created, the layout of the structure, the structural and constructional solution and the evaluation of the present state of the structure is described.

Experimental and numerical analysis of strengthened reinforced concrete member with rigid boundary conditions
Ptáčková, Kristina ; Láník, Jaromír (referee) ; Žítt, Petr (advisor)
A proposal how to conduct a compression test of reinforced concrete objects with one beam inserted from both sides exposed to a four-point bending. A theoretical proposal of the most appropriate form of reinforcement of the reinforced concrete object including a suggestion how to increase its tensile strength based on the chosen crushing load and the positioning of the beam (static calculation). Presentation of the project, static compression test measurement and all the other necessary measurements (elastic modulus, strenth of the material etc.). Development of a mathematical model with the help of Atena software. Evaluation and comparison of the results in analytical and experimental part of the project. Recommendations for implementation of similar experimental tests.

Experimental and numerical analysis of load test concrete slabs
Jedlička, Lukáš ; Láník, Jaromír (referee) ; Žítt, Petr (advisor)
This bachelor’s thesis describes a design, making and experimental load test of reinforced concrete element, which has been selected as a slab. The part of laboratory work was production of testing ensembles and assessment of their physical and mechanical properties. The data from experiment were compared with the results of simulated load test in software Atena 3D, that is using for nonlinear analysis the finite element method. All results were compared with numerical analysis from valid norm.

Evaluating of actual state of existing agricultural building
Skácel, Pavel ; Láník, Jaromír (referee) ; Schmid, Pavel (advisor)
This bachelor thesis deals with agricultural buildings and pre-construction survey of the selected building. In the introductory part is mentioned the history of the development of agriculture to the present. Subsequently is discussed typology of agricultural buildings for animal housing and buildings for storage purposes. The second part describes the technical and constructional solutions selected agricultural building , evaluation of the current state, conceptual design necessary construction arrangements, diagnostic methods detailed survey and drawing documentation.

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.

Diagnosis of the fire damaged bridge
Olejková, 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.
