General Information

Main field: Technology.
Elective Compulsory for: V3
Language of instruction: The course will be given in Swedish

Aim

Analysis of bars, beams, trusses and frames belongs to the most common computing tasks for a structural engineer. The aim of the course is to give knowledge of how to define physically correct models and to use them for solving engineering problems. The generality of the element based analysis method is emphasised by the fact that also one-dimensional flow problems such as thermal conduction, diffusion and groundwater flow are treated.

Learning outcomes

Knowledge and understanding
For a passing grade the student must

• be able to theoretically model bars, beams, trusses, frames and one-dimensional flow problems such as thermal conduction, diffusion and groundwater flow.

Competences and skills
For a passing grade the student must

• be able to use element based displacement method to analyse trusses, frames and one-dimensional flow problems.
• be able to choose suitable models for analysing structures, including dividing the structure into elements, defining degrees of freedom, and defining support conditions and loads.
• be able to perform computer based analysis of the structures in question.
• be able to present a clear written description of basic conditions, model for analysing the structure, results, and conclusions from computations performed manually and using computer, for different applications.

Judgement and approach
For a passing grade the student must

• be able to assess the consistency of the obtained results in relation to the assumed conditions and the defined computational model.
