Diagnostic methods for the evaluation of the state of timber structures
Dvořáčková, Soňa ; Anton, Ondřej (referee) ; Heřmánková, Věra (advisor)
This Bachelor´s thesis is focused on diagnostics methods which are destructive, semidestructive and non-destructive. Thanks to these methods, we find out features and characteristics of the material. In the thesis, there is performed diagnostic measurement on a wooden beam and comparing of the results from the method of thorn resistance placement and the results from wood strength measured along the grain. At the end of the thesis there are mentioned statistics calculations.

The Architectural and Engineering Research of the Building Construction
Blaha, Jaroslav ; Heřmánková, Věra (referee) ; Anton, Ondřej (advisor)
The subject of this bachelor thesis is the diagnostic survey of the industry prefabricated hall. The thesis contains options of reinforced concrete diagnostic. Consequential conclusion judges material characteristics of the beam and roof girder.This thesis is focused on localizing the position and average of reinforcement in every single element. Next step is focused on 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.

Diagnostic methods for the evaluation of the state of a timber structure
Rusz, David ; Komárková, Tereza (referee) ; Heřmánková, Věra (advisor)
This thesis is focused on implementation and subsequent evaluation of selected diagnostic methods for a survey of timber structure. The first part of thesis describes wood structure and characteristics, the next part is about diagnostic methods followed by diagnostics of specific element of timber structures. The main aim of the thesis is to compare nondestructive, minor destructive and destructive methods for timber structures and their application in the practice.

The methodology of survey and diagnostic methods for the assessment of the state of timber structure
Suchánková, Zuzana ; Anton, Ondřej (referee) ; Heřmánková, Věra (advisor)
The bachelor thesis is focused on study of diagnostic methods and methods of research of wooden elements condition. Theoretical part describes composition and quality of wood, its destroying factors and protection against them. In other part individual diagnostic methods are analysed and they try to describe metodology of research in in-sit. Second analytical parts apply selected diagnostical methods on particular wooden elements that are taken out from construction. The goal of the bachelor thesis is explanation of procedure of wooden elements research. Comparison of individual diagnostic methods that are used for wooden elements is another part of goal.

Diagnostics of ceiling structures - possibilities of using GPR
Resl, Jaroslav ; Heřmánková, Věra (referee) ; Anton, Ondřej (advisor)
The thesis is focused on the overview of the diagnostic methods for engineering surveys. The distribution of ceiling structures according to various parameters is described. The theoretical part then provides an analysis of diagnostic methods for the ceiling structures in more detail. It includes a description of the operating principles of GPR. The practical part explains the construction and technical survey of ceiling structures using ground penetrating radar as well as measuring on a physical model. Practical measurement is focused on the use and limitations of the radar.

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.

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.

Diagnostic methods for the evaluation of the state of a timber structure
Balas, Ondřej ; Anton, Ondřej (referee) ; Heřmánková, Věra (advisor)
This thesis is focused on the description and evaluation of selected diagnostic methods used for a survey of timber structures in the field. The first part of the thesis describes a structure and characteristics of wood; the other part provides a description of diagnostic methods followed by determination a level of injury and verification material characteristics of the particular element in the timber structure. The main aim of the thesis is to compare the diagnostic methods for the evaluation of the state of timber structures and verification of their application in practice.

Diagnostic methodology of timber construction
Zouharová, Kateřina ; Heřmánková, Věra (referee) ; Anton, Ondřej (advisor)
The thesis is focused on the appraisal of a wooden roof construction in reconstructed family house in the village Lomnice. The first part describes the structure and properties of wood, in the next section followed by a description of diagnostic methods. The final chapter is complete diagnostics of wooden roof truss with remediation measures. Rating roof truss was based on a survey of sensory and instrumental methods. In the first part was determined the type of roof truss system. In the next section was researched damage of elements and his causes. Remedial measures were established for each type of damage to the components resist any attack as long as possible.

Diagnostic methods for evaluation of construction timber
Heřmánková, V. ; Kloiber, Michal ; Tippner, J. ; Anton, O.
In the present time, there is an effort in the Czech Republic to increase the share of realization of wooden structures. For this reason the necessity to pay higher attention to wood as building material, to learn how to inspect its quality before starting the building as well as of the already bulit-in wood is evident. The paper performs diagnostic methods for evaluation of construction timber being used at the workplaces of the authors. The methods are sorted according to the kind of invasiveness onto non-destructive, semi-destructive and destructive.
