Girder road bridge
Tang, Minh Phú ; Požár, Michal (referee) ; Panáček, Josef (advisor)
The subject of the Bachelor thesis is to design a road bridge with a single span. The bridge carries a road of a class III., category S7,5, over the international roads E442. Three studies have been designed. Study C has been chosen for detailed elaboration. It is a monolithic double-girder post-prestressed construction. The calculation of load effects is performed in Scia Engineer 19.1. Only the effect of vertical load effects was considered, while the horizontal effects of the load were not taken into account.

The reconstruction of the prestressed railway bridge
Macková, Lucie ; Šedivý, Jan (referee) ; Klusáček, Ladislav (advisor)
Diploma thesis describes the design of main structure reinforcement of the railway bridge ,,Gagarin’’ in the 5,872 km of route Český Těšín – Ostrava Kunčice. Reinforcement is achieved by combination of composite slab-shaped channel with the continuous gravel ballast and free additional prestressing cables. There are 3 variants for which the design and assessment of main structure is performed. Evaluation of the options is performed on basis of calculations. There are made additional calculations and drawings for best variant.

Bridge over the Jihlava river
Hibš, Daniel ; Klusáček, Ladislav (referee) ; Panáček, Josef (advisor)
This bachelor thesis deals with the design of a new bridge construction over the Jihlava river in Luka nad Jihlavou. The bridge is located on the road III/4044 at stationing 0,033 km. The bridge evidence number is 4044-1. Three studies were worked out in this thesis. First variant of load-bearing structure projects prestressed beams with composite slab, the next variant suggests dual girder construction and the third variant is prestressed concrete slab. The first study was selected – the bridge made of post-tensioned prefabricated beams with composited reinforced concrete slab. The calculation was carried out in the SCIA Engineer program, and selected outputs were checked by manual calculation. In addition, the time dependent analysis with construction phases was performed.

Bridge over the I/55 road and railway line
Gross, Tomáš ; Pachl, Radek (referee) ; Panáček, Josef (advisor)
The main aim of the diploma thesis is a design of two bridges on D1 highway (Říkovice – Přerov). Structural system of these two bridges is a seven spans continuous beam. The bridges span the rail track and road I/35. The structural system of these two bridges is identical. The preliminary design is processed in two options. The first one considers the use of post-tensioned pre-casted beams PETRA with cast-in place cross beams and composite bridge deck. The second draft considers the use of two slab-beam with the cross beams. Effects of loads were calculated in SCIA Engineer program. The build-up phases were assessed by TDA method. The assessment of the structure was made according to EC.

Bridge ower the Opavice river
Tang, Minh Phú ; Russnák, Adam (referee) ; Panáček, Josef (advisor)
The diploma thesis deals with the design of a road bridge on the I/57 expressway over the relocation of the cycle path, the Opavice river and the local road, which involves the relocation of the access to the waterworks. The bridge structure is located in the territory of the town of Krnov. A study of the area's bridges is part of the project and three studies have been prepared. Study A was chosen for detailed processing. It is a continuous box girder bridge with three spans. The superstructure is designed as a monolithic, post-tensioned structure. A sliding girder is being investigated for the structure's construction. Scia Engineer 18.1 is used to do the load effects computation. Only the consequences of vertical load effects have been addressed, with no consideration of horizontal load effects. The structure was evaluated using limit states, taking into account the impact of construction on its design.

Reconstruction of the engineering structure
Rulíšek, Jakub ; Pinkas, Karel (referee) ; Klusáček, Ladislav (advisor)
This thesis deals with the reconstruction of the Chropyně Engineering Works. The thesis deals with two variants of the structural solution of removing two supporting columns and replacing them with one. The last part of this thesis is a static analysis of measured geodetic data from an old design of a similar solution for this reconstruction. The first option addressed in detail is the additional prestressing and partial strengthening of the truss by concrete, the solution includes the design of the reinforcement of the new column, the design of the strengthening of the footing by additional prestressing and the verification of the fire resistance of the column and the truss. The second variant of the structural solution is the reinforcement of the truss by additional bracing and concreting. In the static analysis of the measured geodetic vertical displacements, a model was created and by successively adjusting the original material and subgrade parameters, the aim was to make the results from the measurements and the results from the calculation program as identical as possible.

Design of reinforced tank
Štramberský, Martin ; Sliwka, Pavel (referee) ; Zich, Miloš (advisor)
The matter of this diploma thesis is a static storage tank for petroleum substances, the study of a solution for appropriate shape of shell and its effort to dihedral for roofing, and the study of effect of the storage of inner roofs walls of the tank to the size of the internal forces. The internal walls are carried out by the method of finite elements in the engineering program Scia Engineering 2013 and on the basis of it, designing of the framing sections of the tank. There is a calculation part of the lower horizontal bias wreaths of the shell and internal supporting wall. All the components are assessed on the 1st limit state of the load-bearing capacity and the 2nd limit state of the application (emergence cracks, limiting voltage in the concrete and a prestressing steel). The existing external wall is assessed only on the marginal status load of carrying capacity. The part of diploma thesis is also drawing documentation, accompanying report and technical report. The goal of the diploma thesis was to design the tank without an occurrence of the cracks in the concrete so as the vertical wall was prestressing only in the horizontal direction and the optimal proposal roof tanks as an addition.
