By the end of this course, students will be able to have: 1. A systematic understanding of the key concepts and aspects for the calculation and design of structures under dynamic loadings. 2. An adequate knowledge of calculation and design of lightweight structures that includes leading knowledge in this field in mechanical engineering in structures under dynamic loadings. 3. The ability to apply their knowledge and understanding to identify, formulate and solve problems of structures under dynamic loadings using established methods. 4. The ability to choose and apply analytical and modeling methods to solve structures under dynamic loadings problems. 5. An understanding of the different calculation methods that are used for the analysis of structures under dynamic loadings. 6. The ability to combine theory and practice to solve structures under dynamic loadings problems. 7. An understanding of the different applicable methods and techniques and their limitations for the analysis of the structures under dynamic loadings. 8. An awareness of the implications of engineering practice in the design and calculation of lightweight structures. 9.

Learning activities and methodology
- Lectures, classes to resolve doubts in small groups, student presentations, tutorials and personal work, oriented to the acquisition of knowledge (1.5 ECTS). - Lab and classes of problems in small groups, individual tutorials and personal work, oriented to the acquisition of practical skills related to the program of the course (1.5 ECTS). Due to the uncertainty about the teaching format to which the health circumstances will lead us during the next course, it is expected to start in the semi-attendance mode, and may lead to training 100% classroom or 100% online depending on the evolution of the spread or control of the pandemic and the health and hygiene standards dictated by the authorities of the sector.
