Study Guide

Objective

In demanding and exceptionally demanding structural design:

The student is able to apply
- use of stiffening methods in different frame systems and cases
- good properties of the stiffening system
- fire measurement methods
- methods of preventing continuous collapse

The student is able to take into account
- the impact of buckling support on the whole
- the impact of the torsional support on the whole
- the impact of the flexibility of the stiffening system
- impact of building height on stiffening
- impact of building length on stiffening
- impact of horizontal displacements on stiffening
- the impact of the location of the stiffeners on the stiffening

The student is able to calculate and examine
- dimensioning of the NR lattice tendon support
- dimensioning of the torsion support of the beam
- stiffening rigid wall dimensioning
- dimensioning of the stiffening beam intermediate base
- dimensioning of the stiffening log wall
- dimensioning of NR truss top stiffening
- dimensioning of the stiffening of a wooden high-rise building
- dimensioning of the stiffening of a wooden hall building

The student is able to identify
- internal and external forces of the stiffening system
- mechanical operation of the stiffening system
- the mechanical operation of the stiffening system as a whole
- weaknesses and strengths of the stiffening system
- effect of stiffening on acoustics
- the effect of stiffening on the vibration of the midsole

Location and time

Lectures held in the autumn term 2025. The course is carried out as online studies i.e., lectures tied to time but not to place.
Lectures on Wednesdays at 15.00-18.00: 15.10, 22.10, 29.10, 5.11, 12.11.2025.

Materials

- lecture notes
- material in Moodle

Teaching methods

Lectures combined with exercises once a week.
Mandatory homework that encourages you to calculate and provides a routine for solving mechanical problems.

The content and program of the course, working methods and requirements are described in more detail in the weekly plan, which is available in the Moodle course.

Exam schedules

The grade for the course is determined by four exercises done during the course.
If necessary, the exercises can be renewed within a certain period of time when this has been agreed with the teacher.

Student workload

Attendance at lectures is not mandatory.

Students are expected to attend each lecture in order to be able to complete the course.

The course has a steady load due to exercises. Every exercise and lecture requires preparation.

Further information

Students need a computer with dual screens, good internet connection, web cam and headset, to be able to participate in this course.

Evaluation scale

H-5

Assessment criteria, satisfactory (1)

Students fulfill the objectives of the course, and in the relevant realization compulsory parts, at a satisfactory level.

Assessment criteria, good (3)

Students fulfill the objectives of the course, and in the relevant realization compulsory parts, at a good level.

Assessment criteria, excellent (5)

Students fulfill the objectives of the course, and in the relevant realization compulsory parts, at an excellent level.

Assessment methods and criteria

The grade for the course is determined entirely by the four exercises. In order to pass, the exercises must be successfully completed. Homework must receive 40% of the points for the course to be considered completed.

Assessment criteria, fail (0)

The student has not shown sufficient basic knowledge of the subject. That is, either the
student lacks approved parts or he or she performs below 40% of the total combined points of the exercises.

Assessment criteria, satisfactory (1-2)

Course grades 1-5 are determined entirely by the four homework assignments.
The course is evaluated according to a linear evaluation scale. 40% of the total number of homework points is required to reach the passing level.

Assessment criteria, good (3-4)

Course grades 1-5 are determined entirely by the four homework assignments.
The course is evaluated according to a linear evaluation scale. 40% of the total number of homework points is required to reach the passing level.

Assessment criteria, excellent (5)

Course grades 1-5 are determined entirely by the four homework assignments.
The course is evaluated according to a linear evaluation scale. 40% of the total number of homework points is required to reach the passing level.
