Design of steel-concrete composite structure of road box girder bridge on by-road of Bludov
Kuba, Michal ; Marván, David (referee) ; Nečesal, Petr (advisor)
The aim of this work is design and assessment of the box-girder road bridge on by-road of Bludov. Bridge is designed as composite steel concrete bridge with 5 spans with distances between supports of 31,25 m; 40,0 m; 60,0 m; 60,0 m and 40,35 m. Main bearing structure is designed as open steel box-girder with reinforced concrete deck. Box girder is braced with longitudinal and transversal bracings. Main structure is separated for each traffic direction. The bridge crosses river Morava and railway in 2nd and 3rd span, respectively. The category of road I/44 is S 21,5/100. The height of steel box girder is designed as 2,5 m. Bridge will be built by incremental launching method, with in-situ casted concrete deck afterwards. The bridge is designed according to current standards. Supporting elements are designed from steel of class S 355 and concrete of class C35/45.

Building survey and evaluating the state construction
Nguyen, Martin ; Komárková, Tereza (referee) ; Heřmánková, Věra (advisor)
This diploma thesis deal with the building survey and evaluating the state of existing constructions. In theoretical part are described the types of civil engineering surveys and diagnostic methods for conducting a survey of reinforced concrete structures. The practical part deal with describes the structural and technical survey of the production hall in the industrial area Fatra Napajedla, evaluating the strength of concrete on the existing structure through donations cores and verification of compliance with the reinforcement according to project documentation. The last part is focused on a static assessment of selected supporting elements of the structure.

Static load test and the assessment ceiling of reinforced concrete structure built in the 1st half of 20th century
Málek, Jaroslav ; Láník, Jaromír (referee) ; Žítt, Petr (advisor)
This master thesis deals with static load test and static assessment of selected segments of reinforced concrete ceiling construction of the Hennebique system at the Faculty of Arts at Masaryk University in Brno. This thesis contains: the execution of the static load test, the data evaluation of the static load test and the data evaluation of the complementary laboratory testing, geometric orientation of bearing elements, the checking of the ceiling placement in the peripheral position, and the diagnosis of the reinforcing of the construction. This thesis also includes the static assessment according to various standard norm rules and the numerical analysis in ATENA software program.

Reinforced concrete structure of the railway platform roofing
Vodová, Pavla ; Bažant, Zdeněk (referee) ; Šulák, Pavel (advisor)
The bachelor‘s thesis deals with assessment of existing damaged reinforced concrete strucutre of the railway platform roofing according to the original project documentation. Apart from assessment of existing structure, there is prepared a design of two alternative solutions. The first alternative is a remediation of damage structure with description of appropriate diagnostic methods for testing concrete structures and with description of technological process of implementation of remediation. The second alternative is design of completely new structure instead of existing one. This new structure is designed as a monolithic frame contruction with restraint reinforced concrete panel and one – step foundation block. In this bachelor’s thesis there were prepared a design and assessment of sub – sections and work – out appropriate drawing documentation. All static assessments are calculated according to ultimate limit state.

The steel construction of an exhibition pavilion
Petrovičová, Lucia ; Hron, Lukáš (referee) ; Štrba, Michal (advisor)
The content of this bachelors thesis is design and appraisal of the steel construction of an exhibition pavilion. Ground plan dimensions are 39,2 x 50,0 m with approximate height 10,7m. The supporting system of the structure consists of planar transverse linkages which are created by lattice truss.The design is selected from two pre-solved geometrical and structural variants which are compered on the basis of the weight of structure and ultimate and serviceability limit state. From the selected variant is made detailed static assessment and drawing documentation.

The load bearing steel building structure of the car showroom
Hubáček, Ondřej ; Karmazínová, Marcela (referee) ; Melcher, Jindřich (advisor)
This work contains a proposal supporting steel structure of the single- industrial buildings intended for parking motor show / exhibition cars in Brno. Building plan dimensions are 20 x 36 m. The main structure is defined by a planar cross-linked. Transverse bond is formed trusses, connected by purlins. Trusses are on both sides of the structure hinged to the fixed columns. The main beam is made up of trusses with an installation height of 1,5 m at midspan. Distance crosslinks is 6 m. Spatial rigidity is ensured by a system of longitudinal transverse stiffeners. Steel truss rods are made of rolled profiles are pillars of HEB profiles and purlins are designed from rolled profiles I. The design is carried out according to standards EN. Used material bearing elements is steel S 235 (regular steel).

Design of a railway beam bridge
Jedlička, Martin ; Panáček, Josef (referee) ; Nečas, Radim (advisor)
The aim of this bachelor thesis is to design a monorail concrete bridge. Focus will be put to design several preliminary versions of a girder bridge. There will be chosen one variant which will be examined more. I will make an assessment and comparison of this variant from concrete and prestressed concrete. As a result of this assessment I will choose the variant which is more convenient and make drawings documentation. The bridge is situated nearby city of Velké Pavlovice in the South Moravia. The rail is a monorail number 255 from Hodonín to Zaječí. The bridge goes over the Trkmanka brook. Calculation of inner forces is made in SCIA Engineer 2012 program. Design is made according EC standarts.

Analysis of Thermoplastic Pipes in a Soil Environment
Ekr, Jan ; Kuklík,, Pavel (referee) ; prof. Ing. Alois Materna, CSc., MBA (referee) ; Gratza, Roman (advisor)
The doctoral thesis deals with an analysis of thermoplastics pipes in a soil environment, in particularly, pipes performed by using trenchless technologies. In the doctoral thesis, experiments of polyethylene pipes loaded by external hydrostatic pressure were performed. The aim of the experiments was to determine a behaviour and load-bearing capacity of the polyethylene pipes loaded by external hydrostatic pressure. For the experiments, a steel pressure chamber was designed and produced which allowed loading and observing a pipe during its loss of the stability. Mechanical properties of the pipe material were determined based on the tensile and bending tests. The series of detailed numerical analyses of the pipe experiments were performed. Various material models which take into account elastic, plastic and viscous behaviour of thermoplastic materials were used. In addition, series of standardized calculations of polyethylene pipes installed using trenchless technologies were performed. The aim was to create new design diagrams for practical assessment of these pipes placed in the partially deteriorated old pipes. In the case of the deteriorated old pipe, a numerical model for determination of design coefficients was created. These design coefficients were verified with standard values. Then, the results of the numerical model were compared with the results of the more complex numerical model which better take into account pipe-soil interaction of various soil types.
