Serviceability Evaluation of historical concrete floor slab
Dudek, Matěj ; Žítt, Petr (referee) ; Schmid, Pavel (advisor)
The master’s thesis is focused on serviceability evaluation of historical concrete floor slab realized in the third decade of the 20th century. The assessment of structural performance is based on the results of load testing in situ. The thesis defines contemporary load testing requirements followed by the specifications of measuring instruments and the possibilities of displacement measurements during load testing. In addition, it includes structural and historical investigation of the building, methodology and data evaluation of the load testing. Finally, the theoretical computer simulation of executed load testing is run by using software determined for nonlinear finite elements analysis.

Design and performance diagnostics of building
Dušek, Erik ; Žítt, Petr (referee) ; Daněk, Petr (advisor)
The bachelor’s thesis deals with diagnostics of a reinforced concrete road bridge, evidential number 325-021 in Hostinné, Hradec Králové region. The goals are to design and partially execute a diagnostic examination. As a part of the thesis, there is a visual inspection of the bridge and survey of the existing design documentation. The conclusion is dedicated to evaluating the diagnostic results and outlining reconstruction.

Experimental and numerical analysis of composite timber-concrete structures
Zelený, Petr ; Láník, Jaromír (referee) ; Žítt, Petr (advisor)
The master´s thesis deals with wood-concrete composite floors constructions. The work is divided into a theoretical and a practical part. The theoretical part describes methods of construction and materials used for wood-concrete composite constructions. The practical part describes an experimental four point bend test carried out on wood-concrete composite elements and samples. Further, manual calculation was performed according to Eurocode 5 and in program Asteres three variants of test elements were modeled. Each variant had different composite stiffness according to the working diagram of composite elements. At the end, experimental, computational and numerical results were compared.

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.

Structural laminated wood reinforced with composite materials
Kovács, Pavel ; Horák, David (referee) ; Žítt, Petr (advisor)
This master’s thesis describes an experimental program investigating the strengthening of beams of glued laminated timber with composite reinforcement. The work compares the behavior of beams reinforced with composite reinforcement with unreinforced beam and with solid timber beam. The work also deals with identifying and evaluating the physic-mechanical properties of materials.

Bearing capacity of the ceiling structure made by diagnostics and load test
Candra, Lukáš ; Láník, Jaromír (referee) ; Žítt, Petr (advisor)
This bachelor thesis deals with diagnostics and static loading test of floor structures. The thesis shortly described construction systems floor structures, the theory of preparation and method of their diagnosis. The selected diagnostic methods are more fully analyzed and described. Furthermore, the work deals with specific floor structure, which is implemented diagnostics, the load test, static calculation and final design evalution.

Preliminary survey of the historic reinforced concrete bridge
Ježíková, Pavlína ; Žítt, Petr (referee) ; Cikrle, Petr (advisor)
This bachelor thesis focuses on the preliminary survey of a bridge connecting the west and east wing of the Veveří castle. It is a structure of a very high significance because it is presumably the oldest preserved bridge made from reinforced concrete, it was completed in 1898. A visual inspection of the outside and inside parts of the bridge was performed. To examine the quality of used concrete and type reinforcement and finding out the condition of the structure, destructive and non-destructive diagnostic tests were used. Because of the historical significance of the bridge is part of the thesis devoted to the history of bridge construction and the author of the Veveří Bridge and the pioneer of reinforced concrete constructions in our country professor Josef Melan.
