• Being able to calculate a concrete beam regarding; shear force, bending moment and deflection in according to EuroCode 2

Main purpose

The purpose is to obtain knowledge about statics used for prefabricated concrete element building with the goal of implementing the design of concrete element buildings.

Knowledge

After completion of the course, the student must:
– have knowledge about statics used for prefabricated concrete element building with the goal of implementing the design of concrete element buildings.
– Obtain knowledge on commonly used joints.

Skills

After the completion of the course, the student must:
– Be able to complete a building structural model comprehend the corresponding calculation model.
– Be able to determine the horizontal transfer of forces to walls in a statically determinate and a statically indeterminate wall structure, using elastic or plastic distribution of forces.
– Be able to understand and use the effective design concrete compressive strength used in plastic design of concrete structures
– Be able to explain the principles of the strut and tie model and to solve simple tasks using it.
– Be able to use the Stringer method in the calculation of walls and diaphragms.
– Be able to complete stability calculations of walls both for one storey buildings and multiple storey buildings.
– Be able to calculate the strength of shear walls (Strut and tie model, the Stringer method and vertical load bearing resistance).
– Gain an understanding of casting joints and be able to calculate these in accordance to DS/EN 1992-1-1.
– Be able to calculate some of the commonly used joints.

Competences

After completion of the course, the student must be able to use knowledge and skill within all subject areas to plan and make relevant choices of techniques and theories in order to solve structural design project.

Evaluation

Examination

Prerequisites:
In order to register for exam, ALL course assignments must be handed in on WiseFlow during the semester.
At least 80% of the assignments must be handed in before a given deadline in order to register for the exam.

Type of examination:
Oral Exam with an external examiner.
25 minutes per student in total incl. grading.
The exam will be based on course assignments solved and handed in to given deadlines during the semester.
The student must bring all the assignments on paper for the exam.

There is no preparation time before the exam.
On the exam day, there will be a draw between the subjects covered by the course assignments. Several course assignment may enter into the drawn subject.

Re-exams:
Evaluation is performed as an oral examination using the same method as the ordinary exam.

Grading criteria

Grading based on the Danish 7-point scale.

Examinations account for 100% of final grade.
