The subject of this thesis was to design and assess the load-bearing structure of the grandstand roof at the sports stadium. The ground plan dimensions are 35x70 m. The object will be located in Moravské Budějovice. The construction is made of grade steel S355 and steel fasteners. Assessments were created for 2 variants. Variant A with truss, Variant B with plate girder. The truss variant, which is elaborated in more detail, was evaluated as more advantageous.

In this master's thesis a steel structure of roofed stands of a sports stadium is developed. Inner forces and design of elements are solved with the program Scia Engineer. The computational model is designed as a three-dimensional bar structure. Main elements are also designed by hand for verification. Elements and joints are designed according to ČSN EN 1993. Anchorage of columns is designed as semi-stiff. Three variants differ in type of longitudinal bracing. The most convenient, a model with truss bracing, was worked out in detail.

The object of this thesis is to design and assess steel structure of multi-storey office center in Nový Jičín. The object is supposed to have an rectangular shape with dimensions 54 x 72 m and roofed atrium in the middle. The object has 6 overground floors. Roof height is 29 m. Two construction variants were designed and assessed. Longitudinal and transverse rigity of variant A is ensured by truss bracings and variant B is braced by bracing frames. Floor structurs of both variants are made of steel secondary and primary beams, which are supported by steel columns. Facade and atrium roof cladding is made of glass panels.

The content of the master’s thesis is a design and evaluation of the timber construction of roofed footbridge for pedestrians and cyclists across the river Bělá in Jeseník in two different options of structure. The final version is solve in detail. It is a bridge with a span of 32 m and width of 4 m. The supporting structure is made of two two-hinged arch of glued laminated timber with lower deck and steel suspender. The bridge deck consists of two main girders, cross beams and stringers. Roof is from arches, roof beams, steel columns and cross beams. The stability of the whole construction is provided with horizontal longitudinal bracing in the plane of the deck and in the plane of the roof. The calculations are processed according to Czech technical norms ČSN EN.
