Diagnostics of steel fiber reinforced concrete industrial floors
Kuře, Václav ; Láník, Jaromír (referee) ; Schmid, Pavel (advisor)
This final thesis is divided into two parts. The first, theoretic part is focused on issue about industrial concrete floors, their production and adjustment. Special attention is paid to the mineral shakes, steel fibres and concrete, which is used to these constructions. There are more information about specific standardized tests of steel fibre concrete and some damages of concrete floors in other chapters. Second part of the diploma thesis is practical. Theoretical knowledge are applied to the actual construction. Survey methodology and diagnostic work are also desribed. Data processing and evaluation with the commentary is also attached to this part. The conclusion summarizes the results and selected findings relating to the issue are also included there.

Bridge across Bystrica creek
Nani, Pavel ; Glovina, Filip (referee) ; Zich, Miloš (advisor)
The subject of my diploma thesis is a detailed static calculation of the post-tensioned concrete road bridge across Bystrica creek near Banska Bystrica in Slovakia. The bridge is element of turning ramp a motorway R1. The spatial curvature continuous bridge has 9 fields. It was made a spatial curvature computational model of the bridge for a structural analysis. The model was comparison with a straight computational model of the bridge. It is made comparison effect of the construction bridge in stages on the size of the internal forces too. The load-bearing structure was checked according to CSN EN 1992-1-1, CSN EN 1992-2 and CSN 73 6214.

Influence of dosage of steel fibres on the loss of consistency of fresh concrete and compresive strength of hardened concrete.
Kuře, Václav ; Źalud, Oldřich (referee) ; Vymazal, Tomáš (advisor)
Bachelor work is focused on problems of a consistency of fresh fiber reinforced concrete. The consistency was characterized by a slump test and by a test of spilling how is it described in ČSN EN 12350. Obtained results are compared with a reference sample of a fresh concrete and between themselves. Further the work is focused on volumetric changes during maturation which are integral part of physical properties of the concrete. Influence of a dispersed reinforcement was monitored on the cube strength in plain pressure of individual mixed sample too. Total evaluation of tested parameters is states at the end of the work including comment about possible ways of interference of tests.

Design of simple engineering structure
Macková, Lucie ; Navrátil,, Jaroslav (referee) ; Klusáček, Ladislav (advisor)
Bachelor’s thesis processes methodology of calculating the deflection according to norm EN 1992-1. First of all it deals with the theory necessary to understand the whole process and explanation of each step. Next learned lessons are applied in the model calculation of deflections, which is performed at 3 beam elements of different construction heights. The resulting values are compared to point out changes in the final deflection according to different dimensions of the structure.
