Mountain hotel in Velké Losiny
Kašíková, Anna ; Barnat, Jan (referee) ; Šmak, Milan (advisor)
The work deals with the design of a load-bearing wooden structure of a mountain hotel in the foothills of the Jeseníky Mountains. It is a building without cellar, two floors and a attic room. The floor plan of the building is 17 x 30 m with a porch of 3 x 10 m. Height of the building up to the ridge is 13.2 m. The design of the roof structure has been chosen from 2 different variants. Material usage consist of grown wood of class C24, glued laminated wood of class GL32h and steel S355. Static analysis was calculated by Dlubal RFEM software.

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.

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.

Joining components by forming technologies
Hudeček, Marek ; Šlais, Miroslav (referee) ; Peterková, Eva (advisor)
The project elaborated in frame of bachelor's degree B-STI gives an overview about methods of joining parts primarily made from sheet. Most of these methods are implemented by cold forming technology without machining. In great detail is described joining parts from sheet using technology of seaming in bachelor thesis. Using a new materials in production and requirements on decrease cost require application modern way of joining, some of them are mechanical coupling procedures and joining by deformation strain.

Mountain hotel in Beskydy
Kubášková, Barbora ; Buchta, Stanislav (referee) ; Šmak, Milan (advisor)
This thesis solves design of timber structure of mountain hotel in Beskydy. The hotel is two-storey building with residential attic and no cellar. The ground plan of the building is about 15x26 m and height of the building is 14,76 m. The type of roof timbers was chosen from two options. There was used structural timber of the strength class C24, glued laminated timber of the strength class GL24 and steel S235. Program Scia Engineer was used for the static analysis of the structure. There was made only linear calculation.

On the effect of tempering and storage conditions of rubber parts on final joint cohesion
Jílková, Ingrid ; Kalivoda, Milan (referee) ; Píška, Miroslav (advisor)
This bachelor’s thesis deals with an analysis of waxing phases occurrence on the surface of the technical rubber which is used in the automotive industry. The theoretical part of this thesis deals with a composition and manufacturing of the rubber. It is focused on the composition of rubber compounds and waxes. It explains technical properties, reasons (advantages) of the ingredients in the rubber components. Next, it also clarifies the substance of the wax and its use in relation to rubbers. The theoretical part also clarifies the storage of rubber parts and why is it desirable to identify the wax which is separated on free surfaces of rubber. The practical part deals with a suggestion of the identification methods for the waxes on the surface of rubber. It also presents the comparison of the possibilities of the methods used for the identification of wax and its evaluation.

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.

Static analysis of one joint of timber structure
Sedlák, Petr ; Gratza, Roman (referee) ; Kytýr, Jiří (advisor)
This diploma thesis deals with the numerical modeling of the nail joint of the timber roof structure and it is based on the already realized physical experiment. Totally twelve various solutions, where the isotropic and ortotropic characteristics of the spruce timber and steel components change, have been created. The final values of the joint shift obtained by using of the numerical modeling are compared with results of physical experiment. Program system ANSYS is used.

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.
