Courses:
2 SWS lecture and 2 SWS tutorial, offered every summer semester.
Applicability:
The course is offered as an export for students in the bachelor's degree program in water resources management. It is part of the elective course of study.
Prerequisites:
Mathematics, basic knowledge of statics and strength of materials.
Lecture content:
The lectures and exercises impart knowledge of reinforced concrete construction according to DIN 1045-1. The lectures deal with essential topics from design, construction and typical applications of reinforced concrete as a building material in hydraulic engineering. The corresponding exercises deal with the respective topic on the basis of a calculation example. As part of the course, simple structural components are designed to deepen and consolidate the application. In addition, a visit to a construction site and a laboratory visit are planned.

| Reinforcement of reinforced concrete components General design rules and rules for special components, types and presentation of reinforcement, processing of steel bars, construction of reinforcement cages, preparation of reinforcement sketches, tensile force cover and anchorage |
| Water impermeable concrete structures Water impermeable concrete, moisture transport through concrete, proof of water impermeability, structures made of waterproof concrete - white tank and black tank concept, joints |
| Prestressed concrete Concept, types of prestressing, properties, special features and application examples |
Exercise
The exercises deal with the respective topic on the basis of a calculation example. During the exercises, a simple reinforced concrete component is designed. The exercises can be downloaded before the respective exercise.
- Exercise 1: Internal forces on the DLT and combination of actions (incl. load assumptions)
- Exercise 2: Exposure classes and concrete cover
- Exercise 3: Bending design with tables and by approximation methods
- Exercise 4: Shear force design
- Exercise 5: Column design (model column method)
- Exercise 6: Crack width limitation and limitation of bending slenderness
- Exercise 7: Tensile force design, anchorage of longitudinal reinforcement and reinforcement sketching
Evidence
As part of the course, each student must complete a voucher consisting of several subtasks. The voucher deals with topics that have been taught in the lectures and exercises. The sub-tasks must be handed in 14 days after the completion of the treatment of the corresponding topic in the exercise. Each student must receive credit for at least 6 of 7 possible homework assignments in order to be admitted to the examination. The slips will be defended in a 1-hour discussion at the end of the semester. Successful defense is also a requirement for admission to the exam.
It is desirable that a student of the year agrees to check the assignments against a sample solution (contract as SHK possible for about 20 h).
