Monitoring of buildings in relation to surrounding construction activity
Ledvoňová, Monika ; Heřmánková, Věra (referee) ; Cikrle, Petr (advisor)
This thesis deals with the monitoring of buildings disorders caused by surrounding con-struction activity. The first section describes the methods of monitoring failures, from the detailed inspection to the result evaluation, there is also given an overview of measuring instruments. The second part describes the methodology of passports implementation and contains an example of the object repassport that was violated by tunneling. There is a comparison of passport and repassport. The third largest section describes a practical ex-ample of monitoring object cracks around which the building activity took place. There is a documentation of failures, a description of the measuring spots choise, installation of the bases, monitoring, processing of results and conclusion.

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.

Analysis of critical places in road transport
Doležel, Martin ; Ledvoňová, Monika (referee) ; Bilík, Martin (advisor)
The diploma thesis deals with the modification of the existing intersection of roads I/43 and III/37717 in the village of Lažany in the South Moravian Region. The main road at this intersection is a two-lane undivided road. The intersection in question is the site of frequent traffic accidents. The subject of the diploma thesis is the description of changes in road markings in selected type intersections. The subsequent selection of own connecting intersections, a traffic survey of this location and a draft of drawing documentation consisting in the adjustment of vertical traffic markings and horizontal traffic markings, which will serve to stabilize traffic and minimize the occurrence of traffic accidents
