Risk analysis of load bearing RC structure review
Bohatec, Jiří ; Laníková, Ivana (referee) ; Šimůnek, Petr (advisor)
Master´s thesis deals with the evaluation of existing structures according to ISO 13822, discusses the dangers that can in determining the reliability of existing structures occur. This standard shall consider the risks by analyzing the possible occurrence and impact of defects (Failure Mode and Effects Analysis). In a concrete example shows a process for determining the reliability and suggest the increase. On a practical example I use a universal risk analysis matrix (Universal Matrix of Risk Analysis) with, identify and quantify the significance of the various dangers associated with project implementation.

Strengthening of reinforced concrete frame structure
Jelínek, Tomáš ; Laníková, Ivana (referee) ; Šimůnek, Petr (advisor)
This thesis reviews a strengthening of reinforced concrete column in frame structure. The column is strengthened with angles and battens. This work is divided into three parts. In the first part there is chosen an appropriate theoretical model. In the second part there is described every step of the design and the assessment which is based on two assumptions. Angles are expected to carry a part of load directly. Concrete is confined with battens. Therefore we can expect better deformation characteristics. There was also used a program ATENA 3D to elucidate one of the problems. The third part consists of designing and assessment of a particular column.

Risk analysis of load bearing RC structure review
Bohatec, Jiří ; Laníková, Ivana (referee) ; Šimůnek, Petr (advisor)
Master thesis deals with the evaluation of risks in the course of strengthening reinforced concrete column. It describes the assessment of existing structures according to ISO 13822, discusses the dangers that can occur when determining the carrying capacity of the existing structure. It also describes the different phases of strengthening steel banding, their functions and influence on the overall capacity. Also showing calculation process of strengthening reinforced concrete column, using steel banding, based on standard EN 1992-1-1 and EN 1998-3. In a concrete example of reinforcement is shown a process for determining the carrying capacity and then designed to the increase. In the two examples performs risk analysis using the universal matrix of risk analysis that identifies and quantifies the importance of various hazards associated with the calculation and implementation of the project.

Reinforcement concrete column strengthening via steel bandage
Stloukal, Štěpán ; Laníková, Ivana (referee) ; Šimůnek, Petr (advisor)
The steel bandage is an economical and effective widely used method for strengthening RC columns. Diploma thesis reviews most common design proposals for the types of the bandage with directly loaded and not directly loaded steel angles. This work also includes a comparison of the different constitutive laws for confined concrete. In order to simulate real behaviour of strengthened structure the numerical analysis has been carried out using non-linear software ATENA. According to the European standards and adopted hypotheses the simplified analytical model has been derived to be able to calculate load-bearing capacity of a strengthened column under normal force and bending moment. The proposed model considers the contribution in confinement pressure caused by steel bandage and the contribution of directly loaded angles. In addition, the direct application on real frame structure has been performed.
