Courses:

7th semester: 2 SWS lecture, 1 SWS exercise
8th semester: 2 SWS lecture, 1 SWS tutorial

Applicability:
Compulsory elective module in the specialization studies, especially for the specializations structural engineering and computational engineering.

Previous knowledge:
Engineering Mechanics (BIW1-03, BIW1-04), Linear Algebra and Analysis (BIW1-05), Statics (BIW2-02), Reinforced Concrete Design (BIW2-05).

Lecture content:
The subject of the module is the fundamentals and possible applications of numerical and other computer-aided methods in the field of solid construction. For this purpose, the special material properties of concrete, crack formation, the interaction of concrete and reinforcement and the respective approaches for modeling and discretization are dealt with. Based on this, the application to typical problems of solid construction is carried out by means of examples.

You can find working material here OPAL. OPAL.
