Slides projected during the lessons and lecture notes.
The aim of the course is to provide students with basic knowledge on the stress of structures, on the science of construction and on the characteristics and use of building materials. Methodologies for the design of small buildings in non-seismic areas will be applied, using the appropriate tools for the graphic rendering of a project.
During the course, software for structural verification and Autocad will be used.
Type of Assessment
Intermediate tests and final oral examination. Acquisition of Badges from the Moodle platform.
Intermediate tests are counted for final vote.
Intermediate tests remain valid in the following academic years.
Evaluation criteria: in written tests with open questions or carrying out calculations, the unsuccessful answer and the wrong answer are considered in the same way; the oral exam takes into account: argumentative rigor, completeness, originality, language properties.
Scalar and vector quantities. Oriented segments and vectors. Sum and difference of vectors. Varignon equation.
Static references: Forces: Definition, Characterization of forces. Equivalent forces. Unit of measure of forces. Forces applied to bodies. Sign convention for forces and their designation. Rule of the parallelogram of forces or Galileo. Force systems. Force composition and decomposition: parallelogram of forces method, subsequent result method, funicular polygon method. Static moments of forces. Varignon's theorem. Couples. Moments of couples
Center of parallel vectors. Center of gravity. Determination of the center of gravity of plane figures. Static moments of plane figures. Moments of inertia. Moment of inertia of flat figures
