Problems of Reliability of Steel Members Sensitive to Imperfections
Nezbedová, Anna ; Lehký, David (referee) ; Kala, Zdeněk (advisor)
This thesis deals with the problems of reliability of steel members sensitive to imperfections. Formulas for nonlinear analysis of compressed and bended members are derived. For compressed elements, there is described the issue of buckling, for bended elements it is lateral-torsional buckling. Then a statistical analysis of reliability of these problems is performed and also comparison with the approach described in Eurocode 3.

Load bearing RC structure of office building
Ferencz, Balázs ; Zlámal, Martin (referee) ; Šimůnek, Petr (advisor)
The Master’s thesis is focused on the analysis and design of selected members of load-bearing structure of an administration building according to the ultimate limit states (ULS) and seviceability limit states (SLS). The calculation and the analysis was supported by design software SCIA ENGINEER 2012. Structural analysis deals with the design of the reinforced concrete (RC) flat slab above the 4rd strorey which is particularly supported by RC columns and particularly lies on RC walls. Furthermore, the Master’s thesis contains analysis of some selected columns of last three storeys, column of lowest storey, construction of stairway between 4rd and 5th storeys. The work beside this deals with the calculation and design of foundation of the object. The rest parts of the load-bearing structure are not solved in the Master’s thesis.

Planetarium
Sokolová, Eva ; Šmak, Milan (referee) ; Barnat, Jan (advisor)
The master’s thesis object is to create a design of a load carrying steel structure planetarium. Its ground plan dimensions are 36,1 x 49,0 m. The planetarium hall’s roof is designed with system of trusses and purlins. The projection hall’s roof consists of ribbed cupola with radially arched ribs. The stiffness of the whole construction is ensured with bracings. The walls of the whole object are composed of columns, rails and bracings.

Stress and deformation analysis of railway bridge over the Odra River
Svoboda, Josef ; Profant, Tomáš (referee) ; Fuis, Vladimír (advisor)
This bachelor thesis deals with strain, stress and deformation analysis of the planar truss bridge construction. The aim is to determined the size of axial forces for statically determinate system and then making construction changes to reduce axial stresses in the individual beams in the structure. This structural modification becomes statically indeterminate structure. To solve this problem we consider different positions of the train at the bridge. The obtained values we can use to assess stress and deformation of the structure and the analytical results will be compared with the results obtained using the finite element method.

Study of Precision of the Stability Analysis
Sotulář, Jiří ; Pilgr, Milan (referee) ; Hron, Lukáš (advisor)
The thesis deals with the precision of the stability analysis of the pressed member. The loss of stability of the bukling is determinate by using several metods, which are compared each other. The thesis is partitioned into three parts that works together. The first part deals with the theory of analysis of the buckling stability. Here is described the gradual solution of analytical analysis for real beam and here is described the final compared for ideal, imperfekt and real beam too. It is also short solved buckling by using software. In the second part is compared by using computing systems and anylitical analysis for several basic buckling systems. The results of the compared are summarised in the final graphs and tables for each solved element and systems. In the third part are designed and static checked load-bearing element of steel storage hall. The buckling beams are checked by using findings from the previous analysis.

Steel Structure of Observation Tower
Klimeš, Pavel ; Šmak, Milan (referee) ; Hron, Lukáš (advisor)
The bachelor thesis concerns with the design and static analysis of the lookout steel construction, which has the height of 25 m and is situated in the Žabčice location. The technical report and drawings are included in the thesis as well. The aim of the thesis was to determine the lookout total load (including permanent, live and climate loads), its implementation in the computer software SCIA Engineer 2012.0 and to perform the stress analysis of selected rods, joints and anchorages by means of the manual calculation. The author of the thesis focused on the climatic load due to wind and ice accretion, which was determined with the use of two approaches according to standards ČSN EN 1991-1-4, ČSN EN 1993-3-1 a ČSN ISO 12494. Both the approaches were evaluated and for the less favorable one the static analysis was carried out.

Nonlinear Response of Steel Structures on Statical Loading
Nezbedová, Anna ; Vlk, Zbyněk (referee) ; Kala, Zdeněk (advisor)
This paper deals with the nonlinear response of steel structures to static loads. There are formulas derived for nonlinear analysis compressed, bended and tension members. By compressed elements, there is described the issue of buckling, by the bended, it is lateral-torsional buckling and tension elements are cables. As an example there is an calculation of a suspension two spans pedestrian steel bridge under load action of asymetrical loads. As another possible calculation process, the finite elements method is described.

Family house load-bearing structure composed of thin-walled steel members
Bulíček, Radek ; Melcher,, Jindřich (referee) ; Karmazínová, Marcela (advisor)
The aim of the bachelor thesis is to design and verify load bearing members of single-storey family house composed of thin-walled cold-formed elements. Parking space for cars of timber members is the part of the house, too. The family house is in rectangular plan with dimensions of 9.5 x 10.5 m. The roof of the house is hipped, on the side of the house with the parking place rafters are associated with garage rafters. The following elements were statically assessed: structural members of the house roof (rafters, collar tie, roof bracing), structural members of the ceiling (ceiling beams), reinforcing timber frame, external and internal load bearing walls (columns), load bearing elements of the parking space (rafters, purlins, columns). All assessments were performed according to currently valid standards. The calculation showed that the resistance and serviceability of all components are satisfied.

Reinforced concrete frame construction
Duda, Tomáš ; Strnad,, Jiří (referee) ; Koláček, Jan (advisor)
The bachelor’s thesis describes the design and assessment of the load-bearing part of the reinforced concrete structure of the department store – the frame. Respectively design and assessment of individual structural elements of the this frame at ultimate limit states. This is a rung frame R1, column S1, footings P1 and floor plate D1 above the first floor of this building.
