Pedestrian bridge over the Jihlava river in Třebíč
Vavřička, Lukáš ; Velešík, Marek (referee) ; Koláček, Jan (advisor)
The bachelor thesis deals with design of concrete pedestrian bridge over the Jihlava river. At the beginning two variants were created, one of which was future postprocessed. The cable-stayed construction, whose main support part is created by two pylons fixed to post-tensioned bridge deck, is pin-supported on abutment. Suspension of the deck is implemented by cables pin joined to the top of towers and sides of the deck. Material of the main concrete load-bearing structure is concrete C45/55. The steel elements of structure are made from steel S355, suspenders are designed with steel Macalloy 460. The structural assessment report was processed mostly by hand calculation with use of program MS Excel, for structural check of pylon use of program FIN EC beton was chosen. The load calculation was performed with program Scia Engineer. The drawing was created in AutoCAD software and the visualization in Lumion.

Highway arch bridge
Vavřička, Lukáš ; Šopík,, Leonard (referee) ; Koláček, Jan (advisor)
The aim of the master thesis was a design of arch highway bridge made of prestressed reinforced concrete. In the beginning two versions of construction were designed, with box-girder and double-girder cross section of bridge deck, from which the variant of double-girder cross section in combination with box-girder arch were chosen for further detail postprocessing. The basics of the solution laid in right choice of dimensions of elements creating load-bearing system and construction geometry. Subsequently global beam model was created, which was used to prestress design and structural assessment of ultimate and serviceability limit states of pillars, arches and bridge deck during the building phases, service lifetime and in the end of lifetime of construction. For detail assessment, linear and nonlinear analysis was created using Midas Civil. To check the cross-sectional direction of bridge deck, slab model was made using Scia Engineer software
