Concrete ribbed slab
Dvořák, Vít ; Perla, Jan (referee) ; Strnad, Jiří (advisor)
The bachelor thesis deals with a design of monolithic reinforced concrete, line supported and cross reinforced slab and a design of supporting reinforced concrete ribs. The plan of the slabs is rectangular and one time bent. The content bachelor thesis is calculation and design of reinforcement of slab and ribs. For the calculation was used software Scia Engineer 14 and was checked by manually calculation. The slab is located in the first floor of polyfunctional house. Other parts of the object are not covered by the thesis.

New family house in Poříčí nad Sázavou
Figuli, Juraj ; Perla, Jan (referee) ; Koláček, Jan (advisor)
This diploma thesis involves design and assessment of the supporting elements of a two-storey family house ceiling construction. The slab components are pairs of beams and translations. I have choose two variants of solution for a long span elements. The first variant includes reinforced concrete elements only and in the second one prestress is used for beams, because of reducing construction height requirements. The basic model was evaluate by the calculation program Scia Engineer 2013, so I made 2D model of a slab in the program and joined 1D elements to the slab like a ribs. Selected prestress reduces a construction height, so it matches the desired appearance.

Calculation of thermal resistance of finned heatsink
Kyanka, Radim ; Huták, Petr (referee) ; Toman, Marek (advisor)
This bachelor's thesis is focused on the problem with analytical calculations needed to define thermal resistance of finned heat sinks. First it describes how temperature proceeds at different boundary conditions at fin tip. Than it describes different mechanisms of heat transfer, equlation of heat resistance especially of natural and forced convection. To verify the results there is comparison between analytical equlations written in Matlab program and measuring results.

The design of the recuperative heater flue gas - air
Procházka, Tomáš ; Baláš, Marek (referee) ; Milčák, Pavel (advisor)
The bachelor s thesis deals with thermal-hydraulic calculation of recuperative gas air he- ater. Type of heat exchanger is shell and tube. This thesis is divided to two parts. The first part apprises the most common types of heat exchangers and their use. It contains also description about basic methods and equations for heat exchanger designing. The second part is calculation of heater with software EES. Whole calculation is checked by software HTRI Xchanger Suite. At the end of this thesis are two datasheets, whitch contains designing solutions for heater with plain tubes and solution with fin tubes. Conception of heat exchanger is chosen by TEMA Standards.

Optimization of an aircraft wing rib
Kopřiva, Lubomír ; Suchánek, Miroslav (referee) ; Petruška, Jindřich (advisor)
Topology optimization is a method providing new direction in designing of a technical objects. The aim of topology optimization is to find optimal distribution of material in design space. This diploma thesis is focused on optimization of aircraft wing rib num.6 of the airplane EV-55 using a software HW/Optistruct 7.0 implemented in a software package HyperWorks 7.0. The optimization of the rib was calculated under four different load cases. Resulting shapes of the rib were then tested by strenght calculations in software ANSYS 10.0. Finally, the obtained data of weights of optimized ribs were compared with the weight of the original rib.

Multipurpose load-bearing timber hall structure
Matuška, Martin ; Sýkora, Karel (referee) ; Straka, Bohumil (advisor)
This Master’s thesis is focused on the design and structural analysis of load-bearing structure of a multipurpose hall that is strained by the permanent load, working load and climatic load. The hall has the shape of an elliptical dome. Maximum margin of the structure is 60,0m and maximum height is 18,0m. Main carrier elements of the structure are radially arranged curved beams made of glued laminated timber, class SA(GL24).

Roof construction of extinguishing systems
Mikulincová, Denisa ; Šulák, Pavel (referee) ; Požár, Michal (advisor)
The bachelor thesis deals with the assessment of the existing reinforced concrete structure of the roof on the fire extinguishing facility. The analysis is performed using the Scia Engineer program. A new design is also proposed. Roofing is done with a ribbed board. Part of the thesis is also an analysis of the possibilities of solving ribbed boards in the Scia Engineer program.

The Viewing Tower in Brdy
Kováčová, Kristýna ; Barnat, Jan (referee) ; Šmak, Milan (advisor)
The subjekt of this thesis is a design of a viewing tower located in the area of Brdy. The structure has been created as a 3D model, the internal forces have been calculated with the use o finite element method in a structural engineering software Scia Engineer 15.1. Based on the knowledge of theses forces the design of the structural systems has been done. The materials used on this construction are glued laminated timber and steel. The height of the tower is 25,725 m. The floor plan is a shape of a circle and fluctuating smaller with the gaining height. The main structural systém consists of 8 curved posts which are radiály situated on the circular floor plan. The tower has 3 observational platforms.

Bridge on the II/369 road
Gratza, Jonáš ; Požár, Michal (referee) ; Panáček, Josef (advisor)
The content of the thesis is solved by a road bridge on one span. The bridge is on the road II / 369 across the river Branná. In this work we were drawn from three studies which option was selected No.1. It is post-tensioned plate-grinder construction. Static model with Load Model and its effects was solved in Scia Engineer 15.2. Opinion are processed manually, according to EC. Wind load, snow and horizontal forces from traffic were neglected.

Design of a one-span bridge
Barič, Dominik ; Panáček, Josef (referee) ; Nečas, Radim (advisor)
The subject of this bachelor’s thesis is a design of a plate – girder bridge structure over the river „Svitava“, between the towns of „Blansko“ and „Brno“. The bridge carries a road of a class II, category S9,5/90. Three studies have been designed. Study A has been chosen for a detailed design. It has a character of post - tensioned plate - girder structure. Load analysis is performed in software Scia Engineer 17.1. The design and assessment are done by hand. Load caused by wind, snow and horizontal forces of traffic is passed by.
