Structural assessment of the reinforced concrete chimney
Teplý, Jakub ; Hasala, Ivo (referee) ; Girgle, František (advisor)
The aim of this thesis is assessment of existing condition reinforced concrete factory chimney, who has undergone structural and technical survey, under which was found many failures caused of horizontally tension - significant vertical cracks in the chimney stack. The object of this work will also make appropriate proposals rehabilitation of concrete stack by design prestressed cables monostrand in horizontal direction, grouting open cracks and reprofiling surface of chimney stack.

Strenghtening of the load bearing parts of the production hall
Čížová, Kateřina ; Pinkas, Karel (referee) ; Klusáček, Ladislav (advisor)
The diploma thesis deals with the strenghtening of the supporting parts of the production hall in Drásov. In the first part the existing load bearing capacity of the structure is solved. The next step is to design of strenghtening variants for nonconforming columns and short corbel. Columns and short corbel are strenghtening with monostrand. At the end of the thesis, verification of the load bearing capacity of the strenghtening structure is performed.

Design of reinforced tank
Štramberský, Martin ; Sliwka, Pavel (referee) ; Zich, Miloš (advisor)
The matter of this diploma thesis is a static storage tank for petroleum substances, the study of a solution for appropriate shape of shell and its effort to dihedral for roofing, and the study of effect of the storage of inner roofs walls of the tank to the size of the internal forces. The internal walls are carried out by the method of finite elements in the engineering program Scia Engineering 2013 and on the basis of it, designing of the framing sections of the tank. There is a calculation part of the lower horizontal bias wreaths of the shell and internal supporting wall. All the components are assessed on the 1st limit state of the load-bearing capacity and the 2nd limit state of the application (emergence cracks, limiting voltage in the concrete and a prestressing steel). The existing external wall is assessed only on the marginal status load of carrying capacity. The part of diploma thesis is also drawing documentation, accompanying report and technical report. The goal of the diploma thesis was to design the tank without an occurrence of the cracks in the concrete so as the vertical wall was prestressing only in the horizontal direction and the optimal proposal roof tanks as an addition.

Roof of the swimming pool
Pelikán, Adam ; Šopík, Leonard (referee) ; Stráský, Jiří (advisor)
This diploma thesis is about designing the structure of roof of swimming stadium. Three solutions are created - concrete arc with tie, steel truss slab and concrete pretensioned membrane. One choosed solution - concrete pretensioned membrane - is afterwards developed. In the beginning there are several designs of geometry fulfilling the requirements for given type of structure being created. In part of static calculation, the parametrical mathematical model in form of macro in APDL language for Ansys software has been created. Afterwards all the parameters (initial state of cables, level of pretension, dimensions of membrane and peripheral frame, etc.) has been optimized in order to the membrane be fulfilling criterias for ultimate limit state and serviceability limit state. Afterwards other selected parts of structure has been checked. On basis of designed geometry and design checks in static calculation the drawings of conctruction and designed parts has been created. In the end, the 3D model of the structure has been created in graphical software Rhinoceros. Then visualizations of structure in concstruction stages and after completion has been rendered.

Variant solution of concrete flat slab supported by columns
Fárková, Karolína ; Pulec, Vladimír (referee) ; Perla, Jan (advisor)
The thesis focuses on the design and assessment of a locally supported ceiling slab. The slab was designed in two variants: a reinforced concrete slab and a prestressed slab, both of which were subsequently approximately economically evaluated. To calculate internal forces, a 3D model was created using the FREM 5 program. The structural analysis was conducted using the finite element method and the method of equivalent frames. Both slabs were assessed for ultimate limit state and serviceability limit state.
