Arch pedestrian bridge over the road
Śmigová, Marie ; Nečas, Radim (referee) ; Koláček, Jan (advisor)
This work deal with the design of a footbridge over a four-lane expressway. At the place where the footbridge is going to be designed is a bedrock in a great depth. Two preliminary variants were created, from which was selected the variant of the arched footbridge. Arched footbridge is a self-anchored structure consisting of a supporting reinforced concrete arch and prestressed bridge desk. For this footbridge was elaborated a more detailed study, static calculation and drawing documentation.

Design of a concrete bridge to the ČEZ substation
Pohůnek, Erik ; Nečas, Radim (referee) ; Zich, Miloš (advisor)
The subject of this bachelor's thesis is the design of a reinforced concrete bridge based on the submitted documents. The goal is the design and evaluation of two variants, from which the most suitable variant is selected and processed in detail. The selected supporting structure is designed as a reinforced concrete monolithic frame. The internal forces from the applied load are calculated using the Scia Engineer 20.0 program. The load-bearing structure is assessed for the limit state of load-bearing capacity and the limit state of usability. Dimensioning and assessment of individual parts of the supporting structure is carried out according to valid Eurocodes.

Design of a single span prestressed bridge
Daněčková, Monika ; Panáček, Josef (referee) ; Nečas, Radim (advisor)
This bachelor thesis aims to design a prestressed bridge with one span. The plate girder bridge was selected from the given alternatives. The load effects were calculated by hand calculation using the member model and in SCIA Engineer 22.0. using the slab model. Subsequently, the structure was assessed for limit states.

Single span railway bridge
Janíčková, Lucie ; Koláček, Jan (referee) ; Nečas, Radim (advisor)
The topic of this thesis is a design of an one-span bridge over a river. The construction of prestressed beam bridge with one field with lower bridge deck is preferred out of all developed options. The construction is designed and assessed to the ultimate limit state and the serviceability limit state according to actual EN standards.

Design of a single span frame bridge
Karásková, Adéla ; Tomečka, Petr (referee) ; Nečas, Radim (advisor)
The bachelor's thesis focuses on the design of a pedestrian bridge over a riverbed. Out of three options, a frame structure with a parabolic ramp in a single span was chosen. The load effects were calculated using the SCIA Engineer program, and the results were processed in MS EXCEL. The structure was assessed for the ultimate limit state and the serviceability limit state. The design was made according to applicable standards and regulations.

Pedestrian bridge in Příbor
Škrachová, Ivana ; Nečas, Radim (referee) ; Koláček, Jan (advisor)
The subject of the bachelor thesis is about a concept of pedestrian bridge across the river Lubina in city Příbor. For final design of pedestrian bridge was made three preliminary designs of constructions and one of them was choosen for detailed processing, assessment and making drawings. The choosen variant is made as prestressed concrete's beam with parapets. For calculation of internal forces was used Scia Engineer Software. Assessment was made by method of ultimate and serviceability limit state. A process of constructio's works are not going be treated in this work.

Cable-supported bridge
Adler, Filip ; Glovina, Filip (referee) ; Nečas, Radim (advisor)
The subject of this master thesis is to design a pedestrian bridge supported by cables. There are three variants of studies created for this case and for most suitable one, all documentations were produced. The primary focus of this work is on static design solution with an output of several drawings. Static model for results from load cases included construction stages and was created in Midas Civil. Design and checks were performed by hand calculations, complemented by checks of several sections by IDEA StatiCa software. Analysis and calculations are compliant to up-to-date codes and respect the fundamentals of analysis due to limit states.

Pedestrian bridge across the river Svitava
Bezručová, Kristína ; Koláček, Jan (referee) ; Nečas, Radim (advisor)
The aim of this thesis is the design and analysis of pedestrian bridge across the river Svitava. Three variants were designed. The variant of one-span frame construction with a parabolic haunch was chosen for analysis. The calculation of load effects was made in software Scie Engineer. For evaluation was used MS Excel. The design and assessment are according to the europien standards. The time dependent analysis is not treated in this work.

Beam bridge over a local road
Kunčarová, Edita ; Panáček, Josef (referee) ; Nečas, Radim (advisor)
The aim of this thesis is to design a one-span pre-stressed bridge structure over a local road. There are three possible versions of this particular construction designed as a part of this thesis, one of which was chosen for further design. The structure has been designed and calculated for the ultimate limit state as well as the service limit state. The calculations were made both by software and manually. Scia Engineer 19.1 has been used for software calculations and for the display of internal forces.

Static solution of the ceiling structure of apartment building
Habanec, Kamil ; Nečas, Radim (referee) ; Zich, Miloš (advisor)
The Bachelor thesis deals with the static solution of the ceiling construction of an integrated apartment building. The aim is to design, or change the sizes of the projected structures in the submitted project, to ensure the interruption of thermal bridges and protection against foot noise. Subsequently, their static solution, dimensioning and assessment to marginal states. The elements intended for the solution are ceiling structures above the second upper floor, beams, a connecting staircase and a column. The calculation of internal forces was performed in the student version of SCIA Engineer 20.0 with a comparison of values on an independent simplified model. The work also includes drawing documentation for the aforementioned elements. The calculation was carried out according to the applicable standards and principles.
