ECTS

Prerequisites

Main purpose

The course aims to provide the student with knowledge and understanding of elastic determination of internal forces and deformation in plane structures and in this context use computer software as a quality control.

Knowledge

After the course, the students must have gained knowledge of and understanding within:

• Bar loads in plane trusses.

• Diagrams for internal forces for externally statically determinate structures: Normal force, shear force, bending moment and torsional moment.

• Linear elastic relationship between stresses and strains (Hook's law)

•Center of gravity, moment of inertia, moment of resistance.

• Elastic calculation of normal stress from normal force and bending moment.

• The Robot program for control calculation of reactions and sectional force curves.

Skills

After the course the student must be able to:

• Determine bar forces using the node method and Ritter's shear force method for lattice structures.

• Determine and record shear force curves for structures.

• Determine center of gravity and moment of inertia for arbitrary cross-sections.

• Determine normal stresses from bending and normal force as well as elastic length deformations in steel.

• Use Robot to calculate reactions and shear forces in smaller structures.

Competences

At the end of the second semester, the student must be able to use the acquired knowledge and skills acquired during the semester to perform elastic shear force and stress calculations in arbitrary cross-sections in the subsequent semester projects, as well as length deformation in steel.

Topics
