Slab bridge across the local creek
Štíchová, Kateřina ; Panáček, Josef (referee) ; Nečas, Radim (advisor)
The subject of this bachelor thesis is the design of a load–bearing structure in the village Velké Karlovice, which passes a roadway II/481 across the watercourse. There are three options of design and one of them – the variant of prestressed slab structure is chosen for more detailed elaboration. The span between bridge supports is 19.50 m and total width of the slab structure is 12.00 m. The slab structure is solved in two ways– – by the manual calculation (for check) and also by creation of the calculation slab model in the program. The manual calculation is based on element of 1.00 m widht and 19.5 m length, which is taken out of the slab. The statical model of this element is a sample beam. The internal forces are obtained from the manual calculation and they are compared with the forces of the slab model. The assessments are solved on the slab model according to valid standards.

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 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 a siding
Slovják, Petr ; Olšák, Martin (referee) ; Panáček, Josef (advisor)
The subject of the Bachelor thesis is to design a road bridge. The bridge, part of road II/353, is crossing over a siding. Designed bridge should replace the current one. Three preliminary studies were developed. The chosen variant is designed as single span double-girder prestressed concrete bridge. The span length of the bridge is 23,0 m and pot bearings are used. The load effects are calculated by Scia Engineer.

Bridge over a roundel
Gross, Tomáš ; Klusáček, Ladislav (referee) ; Panáček, Josef (advisor)
The bachelor thesis deals with design construction of two new bridges over the roundabout. Roundabout is part of exit 354 of the D1 motorway. Bridges is located at kilometer 278.786 on road I /11. Three studies were developed. Design of the first study is post-tensioned prefabricated I beams, which are composite reinforced concrete slab. Design of a second study is post-tensioned slab-beam. Design of a third study is post-tensioned doublebeam. For a more detailed assessment of the study was chosen No. 1 - post-tensioned prefabricated I beams, which are composite reinforced concrete slab. Calculating the effects of the load is solved in Scia Engineer. Construction phase was carried out using TDA - temporal analysis. Testimonials are partially controlled by manual calculation.

Bridge across Bystrica creek
Nani, Pavel ; Glovina, Filip (referee) ; Zich, Miloš (advisor)
The subject of my diploma thesis is a detailed static calculation of the post-tensioned concrete road bridge across Bystrica creek near Banska Bystrica in Slovakia. The bridge is element of turning ramp a motorway R1. The spatial curvature continuous bridge has 9 fields. It was made a spatial curvature computational model of the bridge for a structural analysis. The model was comparison with a straight computational model of the bridge. It is made comparison effect of the construction bridge in stages on the size of the internal forces too. The load-bearing structure was checked according to CSN EN 1992-1-1, CSN EN 1992-2 and CSN 73 6214.

Diagnostic and Reconstruction Design of Brick Building in Medlice
Košárek, Jan ; Cikrle, Petr (referee) ; Kocáb, Dalibor (advisor)
Master’s thesis deals with diagnostics and reconstruction of neo-gothic chapel in Medlice. Summary of appropriate testing methods for this chapel is compiled. Visual examination of whole structure have been performed by diagnostics. Masonry element strength was found out at specimens which had were taken out from structure (drill cores and whole bricks). Masonry elements also was tested by Schmidt hammer LB. Mortar was tested by Kucera’s drill. Masonry strength required for static calculation was computed from achieved values. After examination of all structure defects have been designed reconstruction by post-tensioning.

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.
