Shopping gallery
Lorenc, Jakub ; Barnat, Jan (referee) ; Pilgr, Milan (advisor)
The subject of this diploma thesis is the design and assessment of main load-bearing elements od the steel structure of shopping gallery in Hodonín. Part of floor plan is rectangular and rest of it is half-circled. Object's dimensions are 7é m x 147,75 m (and roof overhang 1,5 m on each side), the height of the ridge is 13,43 m and the height of the roof's dome is 22,70 m. It's a two-storey building. The load-bearing structure consist of pin-suported columns, in this case there is max. 8,5 m distance between them in direction of main frame. The distance between main frames is 9 m. The spatial rigidity of the structure is ensured with floor slabs and system of bracings. The cladding consists of sandwich panels, roof's fanlights and dome of glazed areas. Most of elements are made of S355 steel.

Stability problems of laminated structural glass members
Pešek, Ondřej ; Lokaj,, Antonín (referee) ; Brodniansky,, Ján (referee) ; Melcher, Jindřich (advisor)
Transparent and subtle structures are features of modern architecture. Structural glass is constructional material that provides to realize architect's visions and ideas. Glass as a constructional material is more often used as a material for primary load-bearing structures. Realization of safe, reliable and economic glass structure is real challenge for structural engineers because of absence of standards for designing of glass members and elements. Compressed members (columns), bended members (beams) and members loaded by compression and bending (beam-columns) were analysed in the frame of the doctoral thesis whereby the emphasis is being placed on the lack of stability – flexural buckling, lateral-torsional buckling and flexural-lateral-torsional buckling. Measuring of shape and amplitude of initial geometrical imperfections is a part of doctoral thesis. The theoretical analysis describes the behaviour of the member by means of solving the differential equations. The solution according to the second order theory developed for metal members is applied on structural laminated glass members with use of effective cross-sectional characteristics. Numerical analysis is focused on the use of commonly available software based on finite element method in order to predict the load-bearing resistance of laminated glass members. Actual behaviour of laminated and monolithic structural glass members was found within experimental program. The correctness of FEM model and analytical solutions were evaluated by comparing with test results. The goal of the doctoral thesis was determine of buckling curves for calculation of flexural buckling and lateral-torsional buckling resistances by the same calculation procedure as for metal members. Because of small number of experimentally tested specimens the Monte Carlo simulation was performed.

Statical and dynamical analysis of glass structures
Trojanová, Lenka ; Křiváková, Jarmila (referee) ; Němec, Ivan (advisor)
Glass and the glass elements found thein way into almou all area sof human aktivity thanks to technological advances of the last 20 years. The are of construction i sof course no exeption, quite the contrary. These days it is difficult to imagine building without the glass element, whether it is a part of the interior or exterior. Yet the theory on this issue is at a very low level in the Czech Republic. The content of my work is static and dynamic analysis of structures of glass, when it is applied in practice, it will save money.
