Learning Outcomes
The course aims to: • offer the knowledge towards the engineering analysis and the design of civil engineering structures like buildings, bridges, pipelines, geotechnical and underground structures by building the knowledge for the behavior of materials and structural elements. • define normal and shear stresses, strains and deformations that are being developed to any section of a structural element, symmetric or non-symmetric, open or close thin or thick. • improve the knowledge of elastic and plastic behavior of materials. • cover energy techniques and methodologies for the analysis of fundamental and simple structures. • provide the knowledge of instability for compressive members focusing on buckling. Acquiring skills. After the successful attendance of the course the student will have the ability to: • calculate internal forces and convert them to normal and shear stresses, deformation and strain, for elastic and elastoplastic materials and for complex cross-sections. • calculate the maximum moments and in general forces that a simple structure can withstand. • check the failure of a structural element due to flexure or due to the critical external force for buckling. • design a structural element for a specific external force in order not to exceed the maximum strength of the material. • calculate the deformed shape of a structural element so as not to prevent its functionality.
General Competences
  • Apply knowledge in practice
  • Retrieve, analyse and synthesise data and information, with the use of necessary technologies
  • Adapt to new situations
  • Make decisions
  • Work autonomously
  • Work in an international context
  • Advance free, creative and causative thinking
