2018/19
The course aims to provide the students with the necessary notions and tools to understand and interpret the mechanical behavior of structures in relation to the assessment of their safety. The subject contents are presented in three sections, respectively devoted to: mechanical behavior of structural elements, methods of structural analysis for stress and displacement calculation, fundamentals of solid mechanics. Structural analysis is carried out by means of professional software, which is described both from the theoretical and the practical point of view.

Structural analysis is carried out by means of professional software, which is described both from the theoretical and the practical point of view.
By the end of the course the students will learn the fundamental notions about the mechanical behavior of structures and materials, in terms of strength and deformability, the basic concepts of structural safety. The students will understand the simplest models of evaluation of the structural response, being able to select the relevant geometrical and mechanical parameters, as a function of the considered actions. In addition, the students will be able to understand and assess properly the results obtained from the calculations, included those obtained with the computer. The students will be able to schematize and solve a framed structure with professional software, and to provide the results in terms of internal forces and displacements of the structure. Finally, the students will be capable of assessing the strength of sections and the stability of structural elements.

Wide usage of mathematical methods and concepts is made all along the course. Knowledge of linear algebra, differential and integral calculus is required. It is assumed that the student is acquainted with the concepts of force system equilibrium, is able to calculate the external reaction forces and to draw the diagrams of internal reactions of statically determinate planar structures.

The course is delivered with lectures in order to present all the topics of the subject. Attendance to all lectures is strongly recommended. The course will take advantage of a dedicated web 2.0 server for the improvement of the study at home. The server will provide interactive applications, periodic tests for self-assessment, a social forum for the interaction among students, professors or assistants, and a framework for wiki collaborative activities.
