The course Mechanics of materials and structures describes the static, kinematic and constitutive aspects which together determine the mechanical response of a structural system subject to external actions, with reference to elastic solids and structures. Focusing on trusses, beams and simple frames, analysis tools are developed during the course that allow to interpret and predict the response of such systems to external loads, pointing out the differences between statically determinacy and indeterminacy. Some elements of continuum mechanics are given, the study of the stress state being dealt with in more detail. The course also covers concepts and procedures for strength verifications and for buckling verification of compressed elements. In the exercise sessions, sample design calculations are illustrated, in order to make the students ready for the activities to be carried out in the design studios.
Risultati di apprendimento attesi
Lectures and exercise sessions will allow students to: have a good understanding of the elastic behavior of simple structural systems; analyze trusses, beams and simple frames subject to external actions (mechanical loads, thermal effects, support settlements), both with reference to statically determinate and indeterminate systems; carry out strength verifications (for plane stress situations), displacement checks and buckling verifications of axially loaded compression members; carry out the sizing of simple structural members (this ability being a central aspect in the activities that students are expected to carry out in the ‘design studios’).
After a successfully completed course the student should be able to:
identify the purpose and function of various structures,
analyse beams, frames and simple trusses with respect to internal forces, stresses and deformations,
design structures to avoid failure by stregth and buckling.
The topics covered include: (1) the principles of stress and strain, (2) constitutive equations, (3)axial forces, shear forces and bending moments in statically determinate beams, (4) normal and compound stresses in beams, (5) analysis of composite beams, (6) deflections of statically determinate beams, (7) method of superposition, (8) deflections and internal stresses in statically indeterminate beams, (9) elastic column buckling and (10) shear stress, shear flow and shear center.
Students should have a general knowledge of the basic Statics
Modalità di valutazione
There will be a written exam and one oral exam final. The written can be replaced with two mid-term exams. The exams will be administered in class and will test the student’s comprehension and ability to apply material learned in class and through assignments. All tests are in-class.
Midterm Exam: 20%;idterm Exam: 40%
Oral examination: 40%
