Design of a one-span concrete bridge
Barkáč, Erik ; Panáček, Josef (referee) ; Nečas, Radim (advisor)
The subject of this bachelor’s thesis is to design and analysis a one-span concrete bridge. The supporting structure is one-span prestressed slab with the lenght of 20m.the load effect is calculated by Scia Enginner and compared with manual calculation. The design and assesment are according to the europien standards. The time dependent analysis is not treated in this work.

Highway multispan bridge over wide wally
Bobek, Lukáš ; Daněk, Ing Stanislav (referee) ; Klusáček, Ladislav (advisor)
The aim of this diploma thesis is to design and assess highway bridge. The structure is located on the D1 motorway section bridging a wide valley between the Slovak villages Doľany a Klčov. Three variants have been created – box girder bridge with transverse overhangs, a pair of girder bridge and a pair of box girder bridges. The various proposals were compared with each other. For the most valuable option is selected prestressed box girder bridge with transverse overhangs, which are supported by prefabricated concrete struts. The selected proposal was subsequently elaborated in detail, the load-bearing structure is analyzed using Scia Engineer 16. In calculating the internal forces is adjusted for the effects of construction methods, even as time-dependent analysis TDA. When designing the load-bearing structure it is considered the action of permanent load, also loading from transport and temperature. The structure is assessed for serviceability and ultimate limit states according to current standards. The bridge deck is built by incremental launching method. The principle of this method consists of building the segments in a casting yard located behind the bridge abutment. Each segment is matchcast against the previous one and prestressed to the section of structure already built. The whole superstructure is then jacked forward a distance equal to the length of this segment. This process is repeated until the bridge deck is in its final position. Chosen method of construction is very fast and efficient, to the country in the valley isn´t damage during construction.

Reinforced concrete structure of a administrative building
Čačaný, Matej ; Buřič, Pavel (referee) ; Šulák, Pavel (advisor)
The diploma thesis is focused on design and assessment selected parts of the reinforced concrete structure supporting six storey office building with regard to the ultimate and serviceability limit state.This thesis contains a static calculation and technical drawings of concrete slab above first floor, staircase and two columns. For calculation of internal forces was created a 3D structural model in Scia Engineer 16. Assessment of all designed parts of the structure is done according to Eurocode 2 (ČSN EN 1992-1-1).

Design of a one-span slab bridge
Dorko, Patrik ; Nováček, Jan (referee) ; Nečas, Radim (advisor)
Bachelor thesis deals with the design of slab bridge structure.The purpose of the bridge is to transfer traffic across a river. This work includes design of two potential variants. The chosen variant is a slab of trapezoidal cross-section made from prestressed concrete, which was assessed to serviceability limit state and ultimate limit state. Internal forces were determined by computing program Scia Engineer 2015 and compared with manual calculation, using method of resisting width. This work also includes static analysis and drawing documentation.

Spatial reinforced concrete frame of the industry object
Body, Roman ; Šulák, Pavel (referee) ; Šimůnek, Petr (advisor)
The aim of bachelor thesis is design and appraise the structure of the spatial reinforced concrete frame of the industry object founded on foundation slab. The structure is without the cladding. To the calculation of internal forces is used computing software Scia Engineer 2013.1. Roof slab, rung, beam and column are designed. Designed life of the structure is 50 years.
