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.

Nonlinear Analysis of Composite Cross-Section With Respect To Effects of Shrinkage, Creep, Ageing and Temperature
Hron, Lukáš ; Kulhavý,, Tomáš (referee) ; Čajka,, Radim (referee) ; Vráblík,, Lukáš (referee) ; Navrátil, Jaroslav (advisor)
Advanced computational methods for the analysis of building structures are used more often in engineering practice. Their use is enforced not only by the demands for aesthetics, functionality and high economy of the construction, but often directly by code provisions and requirements. Therefore, it is necessary to provide for an engineer the robust, but transparent tool, which can be used for an efficient design of structure all over it's design working life. This work deals with the creation of a computational system for time dependent analysis of concrete and composite structures. It is assumed a solid or composite concrete section with possible application of pre-tensioned and/or post-tensioned tendons. Each phase of step-by-step build composite cross-section has a general geometry. The used algorithms give us the possibility of a detailed analysis of the structure in individual construction stages, provide the designer better view on the behavior of structures with respect to concrete aging, shrinkage and creep, relaxation of prestressed tendons and provide an information on the redistribution of internal forces in the structure and in different phases of the cross-section. Stress state of the structure calculated in this way come in useful further in the design and checking of ultimate and serviceability limit states. Results of time dependent analysis are verified by manual calculations and by comparing with the results obtained by simplified methods.

Bridge over the Moštěnka river
Kaut, Tomáš ; Čtvrtlík, Libor (referee) ; Panáček, Josef (advisor)
The content of the thesis is to solve the bridge over the Moštěnka river. It is a bridge with one field. 3 studies are designed, one of that was elaborated within the Framework of this thesis. Was selected option no. 2 concrete prefabricated T- beams with coupled concrete slab. The static´s models were created in SCIA Engineer 19.1 and IDEA StatiCa 10.1 and the reports were processed manuály, according to EC. The effects of wind, snow, acceleration and braking forces and slope of grade line have been neglected.
