Design of the single span bridge in Vražné
Juřenčáková, Jana ; Svoboda, Adam (referee) ; Klusáček, Ladislav (advisor)
The subject of bachelor thesis is a design of single span bridge in Vražné. Within the scope of thesis there are three studies of bridge. Cast-in-place concrete slab super structure was found appropriate and further calculations were assessed. Length of span is 15,00 m. Internal forces were provided by SCIA Engineer and checked with manual calculation. The supporting structure was assessed for the ultimate limit state and serviceability limit state. Calculations were made according to valid standards and regulations.

Utilization of inverse reliability analysis tools for probability based design of selected structural parameters
Lipowczan, Martin ; Novák, Drahomír (referee) ; Lehký, David (advisor)
This bachelor thesis deals with the application of methodology and tools of inverse analysis in regards to probabilistic design of selected design parameters of structure. The first step was to get familiar with the probabilistic design and analysis, then understanding of the inverse analysis methodology itself which is based on artificial neural networks. After researching the topic we could get to the actual issue. To put the theory in practice easier examples were used at first. These were mathematical functions and one practical-based example, whereas the results were known in advance. This simplified a process of checking achieved values. Using software tools and especially DLNNET software allowed us to take on practical exercises. Used exercises are chosen from earlier undergraduate studies at the Faculty of Civil Engineering, Brno. The first of these was a design of reinforced concrete slab, where desired parameters were slab’s height and area of reinforcement. The second one was a design of a diagonal truss screw connection, aimed to size the screw diameter and its quantity.

Slab bridge
Barák, Radek ; Koláček, Jan (referee) ; Panáček, Josef (advisor)
The subject of this bachelor thesis is the design of a load-bearing structure of a perpendicular bridge over the Krupa River behind the town of Hanušovice. The bridge turns the II. class road 446, which is a category of S 7,5. For the design, studies of three variants of one-span bridge are processed. The selected variant is solved by means of an additional prestressed plate of rectangular cross-section of height of 900 mm and length of 21,765 m. It is statically designed as the support storage bridge with length of 19,670 m. The design was done according to ČSN EN 1992 - 2. The calculations of the load effects were performed by SCIA ENGINEER 2015 software. The design and assessmetns are solved according to valid standards and regulations.

Prestressed frame concrete structure
Duranová, Anna ; Nečas, Radim (referee) ; Koláček, Jan (advisor)
The Bachelor Thesis deals with designing a single-span frame structure over the riverbed, specifically a bridge for pedestrians and cyclists. Three studies of the single-span bridge, including their evaluation, were carried out. Subsequently, the variant of the single-span frame bridge with a parabolic deck was selected and drawn up. Dimensioning of the prestressed concrete deck and the reinforced concrete props was performed according to the limit states. The load effects were processed in the Scia Engineer software, and the calculations were made in MS Excel. The calculation procedure adhered to valid standards and regulations.

Reconstruction of the Bridge over the River Moravice
Čtvrtlík, Libor ; Svoboda, Adam (referee) ; Klusáček, Ladislav (advisor)
The aim of the bachelor thesis was designing new loadbearing structure for existing bridge conctruction. From three possible options was selected one, which represents cast-in-place prestressed concrete slab. Design procedures and assessments were performed to comply with the ultimate and serviceability limit state according to valid European standards. The calculation was performed in software SCIA Engineer 17.1 that was partly checked by hand-done calculation. The part of this thesis is also enclosed drawings and visualizations.

Design of a one-span frame bridge
Ondrůšková, Kamila ; Panáček, Josef (referee) ; Nečas, Radim (advisor)
The bachelor thesis deals with the design and assessment of reinforced concrete bridge in one field. From three options, there was chosen a frame construction with the reciprocal haunches for the calculation. In individual chapters, there is described the way of design and assessment. The first chapter is focused on study of the bridge design. In other chapters, there is the describtion of load and combination. Final chapters are devoted to the assessment of construction to ultimate and serviceability limit state.

Prestressed bridge slab
Stoklasová, Andrea ; Panáček, Josef (referee) ; Koláček, Jan (advisor)
The aim of the thesis is to design the one pole slab bridge. As a material of the supporting structure has been chosen prestressed concrete. Three preliminary studies have been designed, one of them is selected as the most appropriate solution, and then further elaborated. The span of the bridge is 20 meters. The load effects is calculated using Scia Engineer 17.1 and then compared by manual calculation. An assessment has been made of the ultimate and the serviceability limit state.

Reconstruction of the concrete bridge in Raškovice
Muroň, Vlastimil ; Pinkas, Karel (referee) ; Klusáček, Ladislav (advisor)
The aim of the bachelor thesis was designing reconstruction of old beam bridge in Raškovice. Unfortunately the documentation wasn't preserved, it was necessary to estimate reinforcement according to the standard ČSN 1230-1937, according which the bridge was designed. The structure was reinforced with a new composite plate and post-tensioning. Design procedures and assessments were performed in accordance with ultimate and serviceability limit state according to valid European standards. Calculation was performed in the SCIA Engineer 19.1. program on beam model of one beam. The thesis include necessary drawings.

Reinforced concrete frame structure of multi-storey administrative building
Zdražilová, Pavlína ; Kraut, Jan (referee) ; Šulák, Pavel (advisor)
This diploma thesis deals with design and assessment of selected parts of the reinforced concrete frame of multi-storey administrative building according to the ultimate and serviceability limit state. The aim of this thesis was to design and assess the reinforced concrete structure of a slab above the first floor, one column, a foundation pad and a staircase. In addition to the static calculation, drawing documentation is included. Internal forces were obtained from the 3D model created in computational software Scia Engineer 16.1.
