Static design of the structure composed of combination of steel and structural glass
Potůčková, Simona ; Melcher, Jindřich (referee) ; Karmazínová, Marcela (advisor)
The objective of the bachelor thesis is to design the load-bearing construction system and its cladding made of a combination of steel and structural glass and to verify its sufficient resistance. The object has rectangular floor plan with dimensions of 7,5x10,5 m and and its total height is 24,5 m. The building is located at the suburban area of the city Ostrava, precisely Ostrava Poruba. The construction is composed of a ground floor and six upper floors. The main load-bearing system consists of steel frame formed by six tubular columns connected beams and sway bracings ensuring the spatial rigidity of the structure. The object was designed according to currently valid standards using ULS and SLS verification.

Entrance hall of multi-storey building in university area
Jež, Matěj ; Melcher, Jindřich (referee) ; Karmazínová, Marcela (advisor)
The objective of the bachelor thesis is to design and verify sufficient resistance of load-bearing construction system and cladding made of structural glass. The object is located in university campus at the suburban area of the city of Ostrava, in district Ostrava Poruba. Floor plan is 8,5 x 12 m. The object is composed of six floors and its total height is 21 m. The object is connected to rest of the building. Main load-bearing system consists of frame made of composite steel and concrete rectangular columns and steel beams. Staircase steel beam and reinforced concrete slab are ensuring spatial rigidity. The object was designed according to currently valid standards using ultimate limit state and serviceability limit state verification.

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.
