Statical solution of reinforced concrete structure
Stehno, Pavel ; Ivana,, Švaříčková (referee) ; Zlámal, Martin (advisor)
In this bachelor thesis I study designing and appraising monolithic ceiling slab, which is statically solved by two - way slab. In order to dimension this load - bearing structure to effect of bending moments will be applied computer simulation. The solution is checked by simple method of total moments. Very important part of this thesis is structural analysis affecting pushing through the ceiling slab. Pushing will be soluted by manual analysis, results will be compared with output values of computer analysis. Critical state sagging of the ceiling slab is solved very marginally. The main purpose of this thesis consists of creation technical report, structural analysis and design documentation of soluted structure.

Design of strengthening of the concrete structure from 1928
Bažantová, Lenka ; Pinkas, Karel (referee) ; Klusáček, Ladislav (advisor)
The bachelor’s thesis is focused on assessment of the existing construction four-storey building. The supporting system consists of cast-in-place concrete frame. The aim of this work is to assess the support structure for the expected loading of the resulting change in use of buildings for residential or commercial purposes. The subjects of assesment are columns, beams, girders and floor slab. In another part of work is suggested by reinforcement of non-conforming elements. The work includes the development of stroctural analysis and reinforcement drawings of reconstructed elements.

Examination of the activity and possibility verification ability of various types of corrosion inhibitors
Kroča, Michal ; Švehla, Vladimír (referee) ; Drochytka, Rostislav (advisor)
The aim of the work is to describe the degradation of concrete structures from the perspective of corrosion of steel reinforcement. The basis of a detailed survey and analysis of additives containing corrosion inhibitors, designed to improve the concrete matrix and increased protection of steel reinforcement. The essential part is a summary of the detection methods designed to verify the presence of inhibitors in reinforced concrete (direct method) or anti - corrosion effect on steel reinforcement (indirect method). Subsequently, to compare the available products in the market based on their characteristics and parameters, including prices and environmental point of view. From the data obtained is drawn optimization calculation, the output of which is to determine nevhodnějšího product for protection of steel reinforcement embedded in concrete structures, especially at a dosage rate specified by the manufacturer.

Possibilities of using GPR to detect reinforcement of concrete structures
Filipu, Martina ; Heřmánková, Věra (referee) ; Anton, Ondřej (advisor)
The aim of this study is to outline how is GPR used to detect reinforcement in concrete structures. In each part the study deals with diagnostic testing methods used for building construction and shows a recognisability of steel reinforcement in concrete. Then it closely examines applications of GPR in a diagnostics of reinforced concrete structures with using Hilti PS 1000 device. In the practical part I conducted a building survey of wall silo using GPR and electromagnetic indicators. The aim was to identify the position of reinforcement which was subsequently compared with the project documentation. The construction survey was carried out as a reason of several serious defects such as cracks and tilting of major part of one of the silo walls.

Survey and Diagnostics of Reinforced Concrete Structure
Blaha, Jaroslav ; Heřmánková, Věra (referee) ; Anton, Ondřej (advisor)
The subject of this master’s thesis is the diagnostic survey of the industry cast-in-place hall. The thesis contains theoretical and practical part. The theoretical part is focused on available options of diagnostic methods and options of materials evaluation. The practical part contains material assessment of chosen elements of construction. This part of thesis is focused on localizing the position and the diameter of reinforcement in every single element. Next step is focused on the quality of the concrete, particularly compressive strength and modulus of elasticity. The modern machines, like Hilti PS 1000 and Profometer PM-630, are used to localize the position and diameter of reinforcement. The quality of concrete is determined by removed bore core. Evaluation of material characteristics of the structure is in the conclusion.

The assessment of existing industry hall structure
Hamrlík, Martin ; Chalabala, Jiří (referee) ; Klusáček, Ladislav (advisor)
The bachelor's thesis is focused on an assessment of existing industry hall structure of a rectangular floor plan. The supporting system design consists of a precast reinforced concrete skeleton. The aim of this work is to determine the structure of the expected loading of a new crane runway. The subjects of assesment are columns, girder of crane runway, short corbel and concrete foot. In other part of the project is designed reinforcement nonconforming elements. The work includes the development od structural analysis, drawing of hall structure and reinforcement drawings of reconstructed elements.

Survey and Diagnostics of Reinforced Concrete Structure
Filipu, Martina ; Heřmánková, Věra (referee) ; Anton, Ondřej (advisor)
The master´s thesis deals with concrete properties and it introduces problematics of building survey. In each part the study deals with diagnostic methods used for building construction. Then it closely examines selected methods, which are used for recognisability of steel reinforcement in concrete. In the practical part I conducted two engineering surveys of reinforced concrete industrial buildings. The main aims were to identify the position of reinforcement in selected elements of crane runway and to evaluate the quality of used concrete. The last part of thesis is focused on static assessment of short corbel of crane runway.

Reinforced Concrete Frame - Design of Selected Part of the Building
Hardubej, Martin ; Zlámal,, Martin (referee) ; Švaříčková, Ivana (advisor)
The thesis is focused on an assessment of existing structures at the four-storey apartment building. The supporting system design consists of a monolithic reinforced concrete skeleton. The subjects of assessment are girders, columns, beams and continuous slab. Another part of the project focuses on the design for reconstruction of nonconforming elements, which are the girders and beams. The work includes the development of structural analysis and reinforcement drawings of reconstructed elements.
