Kotvení předpjaté frp výztuže pro betonové konstrukce
Girgle, František ; Horák, David ; Štěpánek, Petr ; Laníková, Ivana ; Šimůnek, Petr
Non-metallic reinforcement has many advantages, but there are some areas of application that need to be resolved to improve the usage of FRP reinforcement in real conditions. One of the disadvantages of FRP reinforcement is its lower modulus of elasticity, which leads to greater deflections of structures and can also cause early propagation of cracks. The paper deals with the possibility of eliminating this problem by prestressing the reinforcement. It covers several problems related to anchoring and current anchoring methods used world-wide. The paper also mentions some drawbacks of these methods. In an effort to bypass these drawbacks a new anchoring method has been developed. It differs in the way longitudinal forces are transferred from the bar to the surrounding concrete. Basically, it is based on the addition of an additional anchoring member (cylinder) on the surface. This member is made of polymers so the whole system remains completely steel-free and very simple to produce. Before using the system in real structures a series of tests were performed and the results are presented. Also, some prestressed test panels were prepared and compared with standard panels.

Design of Selected Elements of Storeyed Building
Ducháč, Josef ; Horák, David (referee) ; Švaříčková, Ivana (advisor)
The Master´s thesis is focused on the assessment basic parts of the story building. All construction is made from reinforced concrete. The columns, flat plate slabs, flanges and stairways are between the design constructions. The thesis includes working-out of static calculation, drawing shape, reinforcement drawing of all design constructions and results from computer sofware.

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.

Planar antenna arrays for RFID applications
Pochobradský, Jakub ; Horák, David (referee) ; Lukeš, Zbyněk (advisor)
This thesis describes the basic principles of radio frequency identification, basic characteristics of patch antennas, the possibility of their feeding and design of planar antenna series. Are discussed, impedance matching options. The selected antenna arrays were realised, measuring their parameters was down and measured parameters was compared with simulation results.

Design of meander RFID antenna
Horák, David ; Šebesta, Jiří (referee) ; Lukeš, Zbyněk (advisor)
This thesis deals with RFID tags. In the first part of the thesis, the general overviews of the present-day RFID systems are presented. This part of the thesis is focused on the passive back-scatter UHF tags and the advantages of their application in supply chain usage. Subsequently, the electromagnetic simulators CST Microwave Studio and IE3D Zeland are described. These simulators were used to design loaded meander antennas. The antennas were designed for different materials and frequency bands of 867 MHz and 2.4 GHz. The designed antennas were made without as well as with the reflector which allows using the antennas in the vicinity of metals. Produced antennas were experimentally tested in the company METRA Blansko Inc, where one of the most significant characteristics of passive RFID tags – the read range was observed.

Apartment Building - Design of Selected Reinforced Concrete Elements
Jakoubek, Lukáš ; Horák, David (referee) ; Švaříčková, Ivana (advisor)
The bachelor thesis is focused on the continuous static solutions of monolithic reinforced concrete ceiling construction and the three-flight staircase in the five-storied apartment house. The entire structure is designed from concrete. To determine the effects of internal forces used computational design of Scia Engineer 2013.1. Assessment of the elements is performed by the first limit state. Work includes developing a static calculation, design reinforcement drawings, shapes and reinforcement drawings solved elements.

Design of the selected parts of the concrete object
Hrvolová, Markéta ; Horák, David (referee) ; Švaříčková, Ivana (advisor)
The aim of the bachelor´s thesis is the static solution of the selected parts of the reinforced concrete object with drawing documentation included. Project describes the design and assessment of the monolitic slab structure and stairway slab by the first and second limit state. As the part of the thesis is the attachment describing the process of modeling the truss structure. For calculation of the internal forces was used software Scia Engineer.

Design of the Timber-Concrete Composite Ceiling Structure
Válek, Jakub ; Horák, David (referee) ; Švaříčková, Ivana (advisor)
The reconstruction of existing houses is currently a frequent issue. This work deals with the possibilities of reinforcing wooden ceilings with the focus on ceiling reinforcement using an over concrete slab. This suggested ceiling reconstruction work is desirable from the point of view of the rigidity of the object in the horizontal direction. The work includes the proposition for the composite, according to various norms and their comparison regarding the economic side of the design. The work further provides a description of the experiment, its preliminary results and its comparison with the theoretical calculation.
