Pedacogical computer program in structural mechanics

OBS! ANSÖKNINGSTIDEN FÖR DETTA EXJOBB HAR LÖPT UT.
With the increasing use of computers in structural mechanics, teaching tends to give more and more importance to mathematics in order to explain what the software does. However, a deep physical understanding of how structures behave is essential. To develop these skills, a chapter concerning qualitative analysis of trusses, beams and frames is included in the basic course of Structural mechanics. This course is part of the KTH program in Civil Engineering and Urban Management.

The purpose of this project is to develop a pedagogical computer program which will be used during laboratories.

The program consists on several beams and frames which are presented on the screen. For each structure, the students have to guess the form of the bending moment and the direction of the supports reactions. They enter their solutions easily by using a few keys of the keyboard. The program draws the solution corresponding to the entered keys. When testing their solutions, the students get the number of mistakes and have to modify their solution until they find out the right one.

A previous version of this program has been developed in 1994 using Turbo Pascal. This version is now too old and a new version, with several new features, must be developed:

- the layout of the program must be changed.
- a random procedure for choosing exercises must be implemented.
- a system of codes that students get after completion of the lab and that they send to the teacher must be introduced.
- an option, showing the deformation of the structures, must be added.

One or two students interested in programming are sought for this project. They will have all freedom to decide which programming language to use. Knowledge in structural mechanics is not necessary for the project.
