Steel footbridge in Černotín
Kelar, Petr ; Štrba, Michal (referee) ; Barnat, Jan (advisor)
The thesis deal with structural design of steel footbridge for pedestrians and cyclist over the Bečva river in Černotín village. Span of the footbridge is 50 m. The basic material is steel S355 and S460. At the beginning were created two variants. First one is an arched footbridge and the second one is cable stayed footbridge. After evaluation variants was selected the cable stayed footbridge. The selected variant was assessed in detail including joints and bearings. Structure is designed in compliance with valid standards of ČSN EN and corresponds with ultimate and serviceability limit state. For structural design was used software RFEM 5.17.01 of Dlubal company.

Adhesion of Adhesive Joints for Facade Applications Made of Wood-based Materials
Nečasová, Barbora ; Schmid, Pavel (referee) ; Sedlák,, Petr (referee) ; Kovářová, Barbora (advisor)
The presented dissertation thesis is focused on investigating the adhesive properties of façade cladding made of wood and wood-based materials in combination with flexible adhesion/assembly systems. The systems allow the implementation of effective construction joints and provide a solution with uniform stress distribution which allows the transfer of heavy loads, while simultaneously reducing the weight of the entire structure, which is also often connected with substantial cost reductions. Despite all that, little attention has been paid to this area so far. It is not a solution which is properly embodied in technical standards or in designers´, architects´ and contractors´ awarenesses. The aim of this dissertation is to characterise adhesive properties of selected façade cladding representatives made of wood and wood-based materials for the purposes of bonded joint application in a ventilated façade system. To define adhesion of façade joints, numerical and experimental methods are used, taking also various limit conditions into account. The main conclusion of the dissertation is the characterisation of basic parameters which influence adhesion, effectiveness and quality of façade glued joints. The secondary conclusion is the compilation of a simple methodical procedure for testing and implementing façade glued joints. The dissertation also makes a contribution by extending the current state of knowledge of façade adhesive joints.

Glazier's Hall
Kelar, Petr ; Pilgr, Milan (referee) ; Barnat, Jan (advisor)
The bachelor's thesis deal with structural design of Glazier's hall. Dimension of the hall are 9,24 m x 24,51 m. The basic material is steel S355. The main frame is three-hidged frame. Each frames are connected by the purlins and girts. Spatial rigidity of the structure is provided by the rigid frame corners and sway bracings. Part of the design is crane runway for bridge crane from Demag company with load capacity of 5 t. Structure i designed in compliance with valid standards of ČSN EN and corresponds with ultimate and serviceability limit state. For structural design was used software RFEM 5.07.03 of Dlubal company.

Posúdenie vplyvu použitia univerzálneho vrutu a vrutu novej generácie s klzným povlakom
Martečík, Marek
Thesis deals with the assessment of the impact of using the classic universal screw and screw the new generation with a sliding coating on various aspects of the production process. It was judged mainly possibility to join two operations into one: pre-drilling and screwing. This opportunity of screws the new generation would mean omission of pre-drilling at joints in hard hardwood, which would result in savings in labor time and costs for making joints. This option would therefore have a major impact on the economic factor in the production of furniture. Furthermore, it was determined the strength of cordless drill screwdriver needed to tighten screws into hardwoods - beech, and watched the wear on drill bits of cordless screwdriver associated with increased effort on tools of missed pre-drilling operation. This issue relates, for example, the manufacture of chairs, supporting frames of upholstered furniture as well as garden furniture or wooden constructions. During the tests it was used solid beech wood, as a classic representative of the hardwood deciduous wood, widely available and often used in the manufacture of furniture. The focus of this work was to observe the characteristics of the three selected types of wood screws in two dimensions. The results of observations and measurements were noted, photographically documented, analyzed and evaluated.

Lepení spojů zahradního dřevěného nábytku
Knápková, Adéla
Bachelor thesis deals with the influence of humidity on the strength of glued joints of wooden garden furniture by using a mounting adhesive. The joints of solid wood-samples of robinia and spruce were glued with one-component polyurethane adhesive. The bonded joints were exposed to the different humidity at elevated temperature and then it was compared to the strength and resistance between individual woods. Samples were strained on tensile shear strength test.

The Steel Structure of Sports Center
Dežerická, Lucia ; Pilgr, Milan (referee) ; Hron, Lukáš (advisor)
The bachelor thesis deals with the design and static assessment of steel structu-re of sports center. The object has a rectangular ground plan with lenght 56 m, width 36 m and height 14 m. The object is situated in Brno. The supporting structure is made up of cross links, which consist of 11 lattice arc-shaped trus-ses placed on columns. The main structural element is steel grade S355, except columns of cross links, these are designed in steel grade S235.

Detail analysis of complex connection in the structure
Hokeš, Filip ; Hradil,, Petr (referee) ; Kala, Jiří (advisor)
The main objective of the thesis is to find and describe dependence between load carying capacity of a pin connection and a pin hole drilling. The dependence will be made in according to standard ČSN EN 1993-1-8, by theoretical solution and finally by finite element method in the ANSYS system. The second objective of the thesis is focused on a verification of load test results by numerical methods. Numerical solution will be made up in two analysis with different types of finite elements. The most fiiting model will be used as a basis for description of the relationship between capacity and diameter of drilling.

Analysis of current lead joints inside HV current transformers
Pálka, Marek ; Váňo, Pavel (referee) ; Drápela, Jiří (advisor)
The main focus of the dissertation thesis is determine the size of the fastening screw connection and fastening torque of the connection, which will be applied during assembly of the instrument current transformers and sensors. The large part of thesis is an experimental measurement of the proposed configurations of connections and modelling (simulating) certain model of connections in Ansys and SolidWorks analysis programs. The result of the dissertation will be design of tightening of the connection according to transient resistance and thermal losses.
