Monitoring masonry buildings affected by the surrounding construction
Kirschbaum, Adam ; Heřmánková, Věra (referee) ; Cikrle, Petr (advisor)
This bachelor’s thesis deals with monitoring of a building object affected by a surrounding construction. In the first, theoretical part the defect of wall constructions, ways of measuring wall cracks and possibilities of a static load are described. The second, practical part deals with monitoring of a multi-storey building which was damaged by a building of a neighbouring object in the gap site. It covers the inspection and documentation of the damage and the description of the applied methods. The results of measuring are elaborated graphically and analysed in connection with interventions to the construction.

Survey and Diagnostics of Brick Structure
Brothánek, Jan ; Heřmánková, Věra (referee) ; Anton, Ondřej (advisor)
The diploma thesis deals with a structural and technical survey of the surviving cellar of the German House in Brno. The first part of the thesis is devoted to the theoretical description of the constructions, methods performed and their evaluation concerning the investigated space. The aim of the survey is to determine the strength characteristics of the masonry and on their basis to propose appropriate rehabilitation and structural protection.

EVALUATION OF MASONRY BUILDINGS STATIC SECURING EFFECTIVENESS
Ledvoňová, Monika ; Šulák, Pavel (referee) ; Šulák,, Pavel (referee) ; Pospíšil,, Pavel (referee) ; Cikrle, Petr (advisor)
The theses looks into the evaluation of the efficiency of statical support of masonry buildings based on the measurements of changes to the crack width of the building. Monitoring of building is one of the main tools for their evaluation, in addition to the initial inspection and survey. In this way, monitoring is given in standards, for example in ČSN ISO 13 822 Bases for design of structures – Assessment of existing structures [1]. The first theoretical part is focused on defects and failures of brick masonry and methods of its monitoring, especially the measurement of displacements in cracks in masonry buildings with a special focus on the use of Hollan crack measurement gauge. The research part listed chronologically alternatives of structural support, both implemented during the construction works or afterwards. The comprehensive chapter then describes in detail wrought iron rods, this work deals with the testing of these rods in its laboratory part. The entire issue of practical part closely focuses on masonry estates built between the 1850s and 1950s and it is divided into two separate chapters. One part deals with laboratory tests of wrought iron rods, as one of the main reinforcing elements of historic masonry buildings that belong to the period in question. These elements were tested non-destructively (tests using a hand-held hardness tester and a hand-held X-ray analyzer) and subsequently also subjected to destructive testing, in which tensile tests of these rods were performed, including their joints. The subsequent practical part is focused on the complex monitoring of a selected brick building, which was damaged by bordering construction activities, specifically the construction of a multi-storey residence in its immediate vicinity. The results of this measurement enabled the design of a methodology for monitoring multi-storey masonry buildings, which completes and concludes the whole topic.

Static provision of castle
Kulla, Lukáš ; Bažant, Zdeněk (referee) ; Strnad, Jiří (advisor)
The aim of this final thesis was static protection for castle in Miroslavské Knínice. It was necessary to explore several respects and find signs of violation. Next analyze and propose suitable assurance of individual parts. Separe into the stages of construction and to consider the proposal in terms of ensuring the resistance of materials. Finally create a detailed documentation in the range suitable for performance. Based on engineering geology and visual survey was designed horizontal bracing prestressing cables at three levels. The first level "A" consists of a closed circuit of prestressed reinforced concrete passports, supplemented by the cross and construction of prestressed reinforced concrete passports. Next level "B,C" is used to secure the top of the building. Levels “B,C” are proposed using prestressed cable in spare cable channels.

Survey and Assessment of Brick Building in Brno, Palacky Street
Španihelová, Ivana ; Anton, Ondřej (referee) ; Cikrle, Petr (advisor)
The thesis summarizes the methods used to test and evaluate the characteristics of vertical masonry structures and further shows the evaluation procedure according to ČSN ISO 13 822. In the second part of this work there is a practical example of brick building assess-ment process, including determining the strength of the walls and the conversion of select-ed critical elements of the existing structure – window pier and wooden beamed ceiling.
