The work deals with issues of evaluation of the shear properties of timber structural materials, particularly CLT elements. The work contains an overview of extensive research so far presented scientific studies dealing with the characteristic shear properties of wood. In the practical part was carried out the experiment dealing with the failure mode of transverse lamellae of CLT elements that were exposed to shear stress. There were observed individual effects that this may affect the material properties. In the first part of the experiment were performed numerical models using FEM. In the second part, the test specimens were tested in three point bending. Here, attention was paid to the influence of macroscopic properties of wood on the distribution of stress cracks and shear strength, the tests were recorded using DIC system.

The subject of this thesis is a construction technology project object Yacht Club Hlučín. The basis for the elaboration of this work is the diploma thesis from Ing.Radim Kučera - Yacht Club Hlučín. This thesis includes technical report construction technology project, coordinating the situation with the construction of wider relations of routes for transportation of main materials, time and financial plan of the construction according to the technical-economic indicators, drawing building equipment, scheduling, inspection and test plan, technological regulation for the implementation of the gross substructure, itemized budget and the plan for OSH implementation in Yacht club Hlučín.

Basic of this Diploma thesis is Civil construction in Kostelec nad Orlici, which is in a part of city, where is planning off-grid community housing. Part of off-grid community housing is considered a partially sistainable civil construction, serving both for cultural use through the club, for commercial purposes such as various salons (hairdresser, massage or shop), as well as for sports activities with the possibility of small refreshments, such as bouldering, climbing wall and exercise hall. Four sustainable (off-grid) familly houses, which aren´t the subject of this thesis, are considered. Object SO01 – Civil construction is designed as a partially basement, two floors. The shape of the object is designed as several blocks with different height levels. From a material point of view it is a wooden building from the system of large-format laminated wood panels (CLT). The basement is designed with a waterproof reinforced concrete so-called white tub and prefabricated ceiling panels SPIROLL. A facade is made of wooden cladding, cement-fiber boards or thin-layer silicone plaster. A roof of the object is partially flat (vegetation and walkable) and a shed roof with a slope of 5°. A dance hall and the rest of the club + exit is located in the basement. A sanitary facilities, a technical room and a main entry with reception is also located in the basement. Right in the middle of the building is a climbing wall that runs across all floors. To the right of the climbing wall is a shop, exercise hall and staircase. To the left side are a sanitary facilities, a boulder (low climbing wall) and separate staircase for a office space on the 2nd floor. Behind the climbing wall is a bistro with entry for a terrace and entry for the club. There are some establishments like a hairdresser, a cosmetic salon, a tattoo salon and a massage salon on the 2nd floor. There are an entrance to a terrace above the bistro and a staircase to an attic and to second terrace as well on the 2nd floo

This diploma thesis goes about the layout of an administration building that is in-tended as a coworking centre or an area for shared cooperation. At the beginning in the literature review is found a brief description of coworking, introduction of wood as suitable material for establishing healthy interior environment of buildings and short display of various construction systems of solid timber buildings. In the applied section of the paper, there are worked up three solutions of cowork-ing centre. Their main differences are in the disposition, size and shape. Applied con-struction systems are the same in all three projects. One of the solutions is chosen as the most suitable and processed into the drawing documentation afterwards. Integral part of this section is the heat passage coefficient calculation and fabric appraisement of the chosen solution.

This thesis is focused on the new building of the nursery school, its construction solutions, specific land placement, and dispositional solutions regarding the cardinal directions. The dispositional building possibilities are further described in connection with various functional units such as barrier-free access, daylight lighting, acoustic, hygiene, and other respective input information. The information is further applied and described with use of specific nursery school solutions.

The thesis evaluates the surface quality during 6000 and 9000 revolutions of shaft per minute. There were used feed rates of the workpiece from 10 to 40 m/min, there were chosen feed rates 10 and 20 m/min for applying the painting matter and for detailed research. Two instruments with different methods of surface evaluation were used for assessing the surface quality. Roughness tester Mitutoyo SJ - 201 P represents contact measurement and Talysurf CLI 1000 is for the contactless measurement. Both of these instruments were used before and after applying the water-based painting matter in the factory of joynery production.
