Fundamentals of reinforced concrete construction (water management) (BWA14)
Table of contents
This course is only offered in the summer semester.
General information
Lecturer: N. N.
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 Eurocode. 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.

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).
Exam
Examination at the end of the summer term: theory and calculation part, duration 120 min, all documents are accepted
Examination requirements: Acceptance of 6 homework assignments and successful defense of the document.
