Bridge on the I/39 road
Pokorná, Šárka ; Svoboda, Adam (referee) ; Panáček, Josef (advisor)
The topic of this Bachelor thesis is design of thle bridge on the I/39 road. Three variants of studies were created. Study C has been choses as the best variant – prefabricated pre-tensioned beams with composite deck. Bridge with one span. Time dependent analysis was taken into account.

CONSTRUCTION-TECHNOLOGY PROJECT OF BRIDGE DEMOLITION AND BRIDGE CONSTRUCTION
Hofírek, Radovan ; Venkrbec, Václav (referee) ; Henková, Svatava (advisor)
This diploma thesis deals with the demolition of a bridge located at the D1 motorway from Prague to Brno. The bridge no longer meets the load and width requirements of today´s standards. The thesis also deals with the construction of a new bridge, which will be expanded into D28/120 category. This expansion will allow for provisory use of the carriageways of one half of the motorway in both directions. The whole reconstruction is very time consuming that is the reason the new bridge is made of prefabricated pre-tensioned girders with a composite bridge deck. This can save time and the new bridge can be open for service in a shorter period of time.

Bridge over a local road
Kováč, Daniel ; Mojzík, Petr (referee) ; Nečas, Radim (advisor)
This master thesis is focused for design, respectively for creating counterproposal of existing structure of Motorway Bridge located at D1 motorway between Jánovce and Jablonov in district Levoča in Slovakia. This bridge is over a local road. The main aim of this thesis is design, analysis and assessment of bearing elements of bridge deck. For purposes of this thesis was created three variants of bridge deck. Detailed analysis was performed on bearing construction from post-tensioned precast beam with monolithing concrete slab. Two mathematic models were used for analysis of chosen variant. First model was spatial 3D shell construction. The purpose of this model was determinate cross spreading line of other constant load and live load. Second, flat 2D model, was for determination creep and shrinkage appeared from long-term load. These effects were observed in at advanced defined time nodes. Outcomes from upper mentioned model were used from design and assessment of bearing elements of bridge deck, design prestressed reinforcement cables and concrete reinforcement rods.
