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.

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.
