Underground culture – adaptation of an old brewery in Litovel
Dohnal, Jakub ; Štukheil, Petr (referee) ; Koleček, Ivan (advisor)
Wonders happen behind the wall. The townspeople and people from the surrounding area are curious, so they head out to see what‘s really going on there. They literally find themselves in a new world. Culture flourishes, crafts are revived, stories of books are told and people eager for knowledge are taught. But the big news is that the city‘s beer quenches the thirst of almost every passerby. In addition, a remarkable path passes through the place along the water and trees. Whether one travels there on foot or by bicycle, one sees a wide courtyard with houses that brings a new spirit to Litovel. The site is located on the northern edge of the historic core of Litovel between the remains of the medieval wall and the watercourse of the Dušní Morava. The complex of buildings with a courtyard extends towards the water into B Street. Němcová and closes with its back to the town centre. The individual buildings were built in different time periods, but the most worthy part is the preserved historical cellars of the former municipal brewery. The city currently has no direct use for the area, so we are coming up with ideas and plans for preserving and upgrading the neglected buildings and the entire surrounding area. The starting point for the adaptation proposal is primarily the historical legacy of the local Litovel beer and the local socio-cultural situation. The aim of the work is the transformation of the current situation into a modern centre of culture, art and education. Strengthening the social life with new attractive opportunities for the residents and visitors of Litovel.

TEMPERATURE MOISTURE PROCESS STUDY IN MODERN WOOD STRUCTURES
Dohnal, Jakub ; Hradil, Petr (referee) ; Straka,, Bohumil (referee) ; Pěnčík, Jan (advisor)
In building structures wood is very often used as construction material and can also be used for supplemental non-supporting structures, e.g. as wood panelling, screening elements, etc. The most common woody plant species that can found in the biotope of the Czech Republic are Norway spruce (Picea abies L.) and Scots pine (Pinus sylvestris L.). Wood as construction material is popular in architect comunity as well as this material like also investors, who prefer living in healthy and natural environments. Wooden structures are also popular with structural engineers for their good mechanical properties and low weight, which, however, depends on moisture. Wood properties vary in every natural way and need to be taken into account at the beginning of the designing process. This dissertation aims to contribute to the description of mechanical characteristics of wood during changes of moisture content in the wood structure. Various experimental tests and numerical modelling were used in the thesis in order to reach the aims. The experimental tests examined mechanical properties at different sample moisture of selected woody plant species. Subsequently, the obtained values were compared with values available in specialist and scientific literature, so that these values could subsequently be used as input values for numeric calculations. The conclusions of the dissertation will contribute to more accurate calculations and further analysis.

Apartment Building Mánesova
Hermanová, Aneta ; Dohnal, Jakub (referee) ; Pěnčík, Jan (advisor)
The aim of this bachelor thesis is an elaboration of contract documents in the level of construction execution. Thesis focuses on new apartment building with almost zero energy consumption. Apartment building is located in Polička, Svitavy district, and is situated in slightly sloped terrain. It is designed as a four-story construction, partly with basement, with flat green roof. On a basement floor, technical facilities and cellar storage could be found. On the above grade levels in total 16 apartment units are located, furthermore with central stairway and elevator. For every level, there are four units, with different dimensions. Foundations of the object are created by reinforced concrete strip footing and two pad foundations. The basement-floor walls are designed to be made from reinforced concrete and above grade parts are bricked up using ceramic blocks. Object is insulated with contact insulation system ETICS.

Computational analysis of auxetic structures application potential in impact absorbers
Dohnal, Jakub ; Skalka, Petr (referee) ; Ševeček, Oldřich (advisor)
Master thesis deals with the analysis of the application potential of auxetic materials in the field of shock absorption (absorption of impact energy). Due to their cellular structure and specific geometry, these materials are characterized by a negative Poisson’s ratio, which means that they are able to reduce their transverse dimension under compressive stress in the longitudinal direction. The aim of this work is to use this interesting property for the absorption of kinetic energy. After the introduction, devoted to the theoretical basis and research in the field of auxetic structures, a numerical FEM model is described in detail. The task of the model is to study the mechanical response of auxetic and conventional cellular structure to an impact loading. An explicit solver in the commercial software LS-DYNA is used to numerically simulate fast processes. The results of the analyses are used to compare auxetic and conventional structures and quantify the differences in their ability to dampen the kinetic energy of the impact effectively and gently. It also serves to demonstrate the influence of individual geometric or material parameters on impact attenuation. At the end of the work, numerical simulations are confronted with available experiments in order to verify the informative value of computational models and to point out the application potential of auxetic structures in the discussion. There are also partial recommendations for their design so that they best serve the intended purpose.

Computational tool for a stress-strain analysis of the mechanically loaded circular and annular plate
Dohnal, Jakub ; Majer, Zdeněk (referee) ; Ševeček, Oldřich (advisor)
The bachelor's thesis primarily deals with the creation of a computational tool for stress-strain analysis of rotationally symmetric circular and intercircular plates. The commercial software MATLAB and its component APP DESIGNER were used for this purpose. The program uses analytical relationships of general solid mechanics to solve differential equations for several types of plates and loads. Part of the bachelor thesis is also a parametric study comparing the outputs of analytical and numerical model based on the finite element method, aimed at identifying the practical application of the analytical solution and its accuracy for a particular case of the plate.

Crematorium with two ceremonial halls
Skřeková, Tereza ; Dohnal, Jakub (referee) ; Pěnčík, Jan (advisor)
The subject of this diploma thesis is the design of a crematory with two ceremonial halls. Building is situated on the high point, distanced from the surrounding buildings. There is a cemetery located five hundred meters from the crematory. Crematory is designed as a modern building, which has one above-ground floor from the most part, except of the large ceremonial hall that has two above-ground floors. This hall is a symbol of this structure. Vertical load-bearing system of exterior walls is 300mm wide made of Porotherm ceramic pieces, with exception of large ceremonial hall designed from reinforced concrete. Non-load bearing wall system is also made from Porotherm ceramic pieces. Roof is designed as a prefabricated rib-and-filler floor, except of the elevated part of large ceremonial hall designed from mono truss girders. The building is supported by the wall footing concrete system combined with the spread footing concrete system under the columns.
