Shear bearing capacity of composite slabs
Holomek, Josef ; prof. Ing. Alois Materna, CSc., MBA (referee) ; Keršner, Zbyněk (referee) ; Bajer, Miroslav (advisor)
The subject of the submitted work is the experimental and theoretical investigation of composite slabs. The work also deals with creation of numerical models of composite slabs. The design of a new type of steel sheeting for composite slab according to nowadays standards requires full scale laboratory bending tests. An alternative to the bending tests are the small scale shear tests. The small scale shear tests as well as corresponding design methods have already been investigated by many researchers. Therefore several test arrangements and corresponding design methods can be found in literature but none of them is included in standards yet. The submitted thesis describes three of the alternative design methods: Slip- Block Test, Simplified Method and Built-up Bars. The test arrangement is proposed to be usable in all these methods. The small scale shear test have been performed in laboratory in several modifications. The results were used to calculate the bending resistance of the slab by the alternative design methods. The calculated bending resistances were mutually compared, compared with the performed bending tests resistances and the resistances by the methods described in Eurocode: m-k method and partial connection method. A sensitivity studies of the input parameters in alternative design methods are presented as well. The optimal design method for use in practice was searched and recommended based on the performed studies, accuracy and laboriousness of the methods. The shear tests were used also to measure longitudinal shear resistance of the additional shear anchors. The alternative design methods were used to predict bending resistance of the slab using these anchors and the results were compared. The numerical simulation of the composite action of the slab by the finite element methods is modelled in Atena software. The models serves to perform parametrical studies and to better understand of the behaviour of the slab in partial composite action.

The Level of Physical Abilities of the Applicants to the Policie of the Czech Republic
Holomek, Josef ; Vindušková, Jitka (advisor) ; Krátký, Petr (referee)
Name of research: The level of physical abilities of the applicants to the Police of the Czech republic The aim of study: The aim of our study is to research the level of physical abilities of the applicants to the police forces in the last 7 years using two test bateries. I will attempt to find out the level of physical abbilities on the grounds of the results of the physical tests in the years from 2003 to 2009. Methods: I was using the method of descriptive statistics to evaluate the available informations. I compared the results of applicants, who passed the defined conditions in physical tests. Further I used the graphical method to demonstrate the curves of abilities of the both groups of applicants, who passed and failed the physical tests. The datas from the physical tests of applicants to the Police of the Czech republic were the source, collected in the police program SOTP. The results: -the level of physical abilities comparing the both test batteries is not declining in average -new test battery is acceptable Conclusion: I hope, that the results in my diploma paper offer the point of view and a valuable asset about the level of physical abilities of the applicants to the police in the years from 2003 to 2009. Key words: applicants, physical abilities, mean average, standard deviation,...
