Working materials are provided in OPAL. For the module part "BIW4-12 Reinforcement of Solid Structures" here, and for the module part "BIW4-12 Measurement and Testing Technology" here.
Contents and qualification objectives:
The content of the module is analysis and recalculation as well as repair and reinforcement of existing solid structures.
After completing the module, students will be familiar with the methods of static-constructive building diagnosis using mathematical and experimental methods. They will be able to analyze existing solid structures with regard to their condition and load-bearing behavior and to plan and calculate the necessary reinforcement measures. Reinforcement with the aid of textile-reinforced concrete is also a focal point.
After completing the module, students will have in-depth knowledge of modern concrete technology in existing and new buildings, particularly with regard to the production, properties and areas of application of high-performance concretes with and without fiber reinforcement.
Teaching methods:
4 SWS lecture and 2 SWS exercise
Prerequisites for participation:
The competences to be acquired in the modules of the foundation course (BIW1-01 to BIW1-11) and the foundation course (BIW2-02 to BIW2-06) are assumed.
Applicability:

Requirements for the awarding of credit points:
Credit points are awarded if the module examination is passed. The module examination consists of a written examination (240 minutes).
Credit points and grades:
8 credit points can be earned through the module.
Frequency of the module:
Module is offered every academic year, starting in the winter semester.
Workload:
The total workload is 240 hours.
Duration of the module:

Exercise
Reinforcement of solid structures
The exercises focus on practical examples. It is shown how the analysis and evaluation of existing structures is carried out and what basic possibilities exist for further procedures. In addition to the technical possibilities, questions of economic efficiency and sustainability are also taken into account.
Practical courses
Measurement and testing technology
2 practical courses (duration 4-5 hours in total) take place in the
Otto Mohr Laboratory
Zellescher Weg 22
01062 Dresden.
| Practical course 1 | Getting to know the measuring and experimental techniques |
| Practical course 2 | Carrying out small experiments |
Certificate
No certificate is required.
Examination
The module is completed with a written examination (240 min).
