Plan curved cable stayed pedestrian bridge
Müller, Radek ; Kaláb,, Pavel (referee) ; Koláček, Jan (advisor)
In my thesis, I created a study of plan curved cable stayed pedestrian bridge. As the main construction material is used prestressed concrete. Suspenders and railing are made from steel. The footbridge has a length of 130,00 meters and a width of 3,70 meters. The plan shape of the structure is composed of two oposite arches. Bridge deck is made of box girder. The bridge deck is single-side suspended on two concrete pylons with a height of 39,00 m. Pylons are supported by suspender.

D - Areas Analysis using Strut and Tie models
Konárek, Lukáš ; Hradil, Petr (referee) ; Zídek, Rostislav (advisor)
The objective of bachelor thesis is the analysis of typical D-areas of reinforced concrete structures. The analysis is performed using methods replacement truss. In the beginning models replacement truss are used for analysis shear bending girder. It is also shown in the individual chapters specific D-areas using spare truss method. These particular truss models are solved by RFEM program operating on the principle of Finite Element Method.

Shopping Center in Ivanovice na Hané
Čech, Martin ; Šmak, Milan (referee) ; Pilgr, Milan (advisor)
Work deals with design of steel structure of shopping center. It is a building with rectangular shape with dimensions 28 x 55 m and a height 11 m and with cylindrical roof with 50 m radius. Main frames are designed with 5,5 m distance and they are made of arc roof truss connected to steel plate columns. Exterior building envelope is made of Kingspan sandwich panels. Roof cladding is designed without purlins and curtain wall is fastened into side rails. Macalloy tension members are used to obtain spatial rigidity of the structure.

Behavior analysis of a ground anchor fixed length in fine grained soils
Chalmovský, Juraj ; Turček,, Peter (referee) ; Hrubešová,, Eva (referee) ; Miča, Lumír (advisor)
Ground anchors represent an important structural element in the area of ground engineering. Despite an extensive usage of these elements, their design is usually performed using simple empirical and semi-empirical methods. An application of these procedures brings to the design a number of simplifying assumptions. The goal of the dissertation is to refine the computational design of ground anchors, analysis and quantification of selected factors significantly affecting their load displacement behavior. Firstly, the finite element method is applied. Two novel constitutive models are used: Multilaminate Constitutive Model for Stiff Soils (Schädlich, 2012) involving post peak shear softening of overconsolidated cohesive soils and Shotcrete Model (Schädlich, 2014) involving tension softening after tensile strength is reached. First constitutive model was used in order to simulate progressive decrease of skin friction along the anchor fixed length. Second constitutive model was applied for the grout material. In the next step, experimental program including several anchor load tests was carried out. The goal of the experimental program was to confirm conclusions from numerical studies and to obtain relevant data for further back – analysis. A newly developed application, in which all the findings from numerical computations and experimental measurements are incorporated, is described afterwards. The application is based on the use of so-called load-transfer functions. The program verification was conducted through series of back analysis of investigation anchor load tests realized on four different construction sites in two different types of fine-grained soils. The verification of the application is followed by series of parametric studies in which an influence of input parameters values is analyzed. Dissertation is concluded by the summarization of the most important findings.

Market Hall
Stloukalová, Tereza ; Šmak, Milan (referee) ; Barnat, Jan (advisor)
The work is focused on the design and assessment of the steel structure. It is a three-aisle hall of the Market Hall, 6.5m high, with plan dimensions 18x30m. The supporting structure consists of sawtooth trusses, which are mounted on swinging uprights. The spatial rigidity of the structure is ensured by longitudinal and transverse stiffeners. The entire structure is designed in S235 steel. The cladding is made of sandwich insulation panels.

Steel Structure of the Office Building
Ruček, Martin ; Pilgr, Milan (referee) ; Hron, Lukáš (advisor)
Main concern of the thesis is a structural design of main load bearing elements of steel, four-storey high administration building. Designed building has 36 m long and 24 m wide rectangular footprint. Roof is shaped into a hyperbolic paraboloid surface. Main load bearing structure is consisting of six main cross sections formed by truss columns, and generally curved roof truss beams, accompanied by storey supporting frames with composite slabs. Overall shape of the roof is defined by warped surface. Cladding of the building is consisting of aluminium facade system.

The Roof Structure of a Multipurpose Sport Building
Málek, Leoš ; Straka, Bohumil (referee) ; Buchta, Stanislav (advisor)
This thesis deals with design of roof structure of multipurpose sports hall located in the city of Blansko. The goal is to use timber and natural resources as much as possible. Emphasis is placed on the maximal prefabrication at the site of production and the speed of assembly at the site of construction. Span of the structure is 40,035 m, length 59,75 m and height 17,525 m. The structure is designed as a three-hinged truss made from the glue laminated timber. The structural model was created by software RFEM of the Dlubal company.

Timber load bearing structure of a family house
Perhalová, Anna ; Buchta, Stanislav (referee) ; Straka, Bohumil (advisor)
The subject of this bachelor's thesis is design and static assessment of timber load bearing structure of the family house. The object is located in Slavkov u Brna. Design of truss structure is based on architectural study by prof. Ing. arch. Ivan Ruller. The ground plan dimensions of load bearing structure are 11,63x15,00 meters and the height of the roof ridge is 6,56 meters. The structure of the roof is made as a rafter system, which is supported on the lattice truss, on the main beam and wall rafters. Horizontal forces are transferred into the wall panels by means of tight members, which are anchored to wall rafters.

The Exhibition Gallery in Olomouc
Morcinková, Eliška ; Straka,, Bohumil (referee) ; Šmak, Milan (advisor)
The aim of this diploma thesis is the design of bearing construction of the Exhibition gallery in Olomouc. The building is of irregular shape with the biggest span of 50 m. The bearing structure in the highest point goes up to 14,6 m. The main design material is the glue-laminated timber GL24h and GL32h. The optimization of chosen parts of the structure has been made and the best option was then used in the detailed structural calculation. The bearing structure consists of circular columns to which the floor beams and roof trusses are connected. The irregular structure of the gallery comprises of three different roof types – flat trafficable roof, double-pitched glass roof formed by pitched cambered trusses and single-pitch roof spanning over the central part of a 20,7 m span. Within the thesis the design and check of the main structure members and connections has been made. The entire structure is pinned and its stiffness is secured by the system of tension rods and rigid floor and roof construction respectively.
