Low-rise Timber House
Doležal, Lukáš ; Bečica, Radek (referee) ; Lavický, Miloš (advisor)
This Bachelor´s thesis processes design of standalone single-storeyed family house with attic, without cellared. The construction system of this building is lightweight frame system. Its benefits are good thermal technical properties and reduced construction time. The documentation is Works for building construction. The design documentation of the thesis is elaborated by computer program AutoCAD.

Analysis of structural response and design methods for shear walls in light timber frame structures
Zajíc, Michal ; Lokaj,, Antonín (referee) ; Kuklík,, Pavel (referee) ; Kuklík,, Petr (referee) ; Šmak, Milan (advisor)
The prediction of shear capacity of light timber frame walls in a multi-storey arrangement is the main focus of this dissertation. The available theories neglect to account for the fact that the shear resistance of the walls may depend on the actual vertical position of the applied horizontal force. However, the actual arrangement of the structures in practice introduces a vertical offset between the wall head height and the position of the resultant of the external horizontal forces. Thus, the horizontal shear force is accompanied by dependent overturning moment. Solving such a problem for partially anchored walls inevitably leads to an iterative calculation. The aim is to provide a comprehensible and less calculation-intensive procedure for multi-storey buildings that would be competitive with existing simplified methods. A model derived from lower bound plastic method was successfully put to the test in a parametric study and compared with limited test results. The results show that the capacities predicted using the novel method compare favourably with the results obtained from traditional theories using a more complicated iterative process. Therefore, the presented single-step approach may be appealing to the industry. A test program was formulated to understand better the implications of the recommended best practice of introducing gaps between sheathing panels. It was set to experimentally verify the difference in the shear capacity for setups with and without gaps between the sheathing panels. The significance of this study is that it informs the industry that the manufacturers’ recommendation to incorporate a gap between sheathing panels would not compromise the structural integrity. Considering the model uncertainty and the safety margins, the introduction of gaps does not alter the strength or stiffness of the wall.

New station of the Czech Mountain Rescue Service in Ramzová made of hempcrete
Harazin, Tomáš ; Pilný, Ondřej (referee) ; Kalousek, Lubor (advisor)
The aim of this project is a design of a Mountain Service station in Ramzová located in the Protected Landscape Area Jeseníky. It is a two-storey rectangular building with a gable roof. It has a light wooden frame with hempcrete thermal insulation with diffusely-open constructions. The roof and the facade are covered with split larch shingles. All materials used are selected with respect to their environmental impact in combination with modern approaches. The building is designed as a near-zero energy building, including an air handling unit, a heat source in the form of an air-water heat pump, as well as photovoltaic panels placed vertically on the structure in the northwestern part of the property. The work also includes research into the properties of hempcrete. Laboratory measurements of a heat transfer coefficient and compressive strength of the material were made on samples of hempcrete and are implemented to the project. The result is a building using today's most advanced technology combined with traditional natural construction.
