Code

CE-STU1

Version

3.0

Offered by

Civil Engineering

ECTS

5

Prerequisites

For exchange-/transfer students:
General admission requirements as well as individual assessment of conditions.

Main purpose

The course builds upon the basic principles of structural steel developed in the previous STD courses. The aim of the course is to enable the student to create structural steel systems and undertake calculations of load bearing steel structures, including connections in ultimate limit state and serviceability limit state.

Knowledge

After completion of the course, the students must:
–  Have knowledge about different types of steel structures (e.g. industrial buildings, hangars).
– Have knowledge about the principles for calculation of plate elements with stiffeners and be able to calculate a chosen few.
– Have knowledge about the resistance of transverse forces (design resistance of webs in plate girders).
– Have knowledge about flange induced web buckling.
– Have basic knowledge of fire design for structural steel.
– Have knowledge of various steel connection types.
– Have a basic understanding of load transfer in steel connections.

Skills

After completion of the course, the students must:
–  Be able to model globally stable structural steel systems.
–  Be able to calculate buckling of plates, eg. in welded plate girders.
–  Be able to calculate cross sections in class 4 using the effective cross section in the ultimate limit state.
–  Be able to calculate a plate girder with respect to lateral torsional buckling.
– Analysis of bracing systems which are required to provide lateral stability of beams and compression members (eg. columns).
–  Be able to calculate restraint in structural parts subject to compression.
– Be able to analyse/calculate some chosen structural steel connections (eg. welded connections in portal frames, design tension resistance of a T-stub flanges in plate girders).

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.

Teaching methods and study activities


The course is scheduled for 14 weeks with 4 lectures each week. Workload for the students corresponds to 138-hour.
Activities vary between theoretical lectures, self-studies, consultation periods in connection to the work with assignments and students presentation of assignments.
 
Student Activity Model
Category 1: 35%, ~ 48 hours:.(Participation of lecturer and students, Initiated by the lecturer): Lessons, scheduled, Excursions, Project guidance, Laboratory work, Exams and tests
Category 2: 65 ~ 90 hours: (Participation of students, Initiated by the lecturer): Assignments, self-study, Project and group work, Homework and preparation for exams, Evaluation of the teaching

Evaluation

Examination

Oral Exam with an external examiner.
20 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.
In order to register for exam, all course assignments must be duly handed in. Course assignments must be uploaded to Itslearing during the semester and to WiseFlow at given deadlines.
There is no preparation time before the exam and it is allowed to bring the assignments to the examination. 
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.

Reexams are performed as oral exam 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.
