AIMS AND CONTENT

LEARNING OUTCOMES

The course aims to provide fundamental concepts on the equilibrium, deformability, and strength of structures, necessary for understanding the basic aspects of structural design. The student will acquire methodologies to describe the mechanical behaviour of beams and trusses, including principles for controlling strength and deformability in relation to the materials adopted. Significant examples drawn from built architecture will be referenced to achieve the objectives.

AIMS AND LEARNING OUTCOMES

The subject aims to provide the fundamental concepts of balance, deformability, and resistance of structures, necessary for understanding the basic aspects of structural design. The first objective is developing the ability to model isostatic systems and to determine their equilibrium conditions in compliance with the principles of statics of rigid systems. The second objective is the acquisition of methodologies to describe the mechanical behaviour of elastic systems, including the principles for controlling the strength and deformability of the adopted materials. To pursue the objectives mentioned above, reference will be made to significant structural examples taken from built architecture. At the end of the subject, the student will have to know the fundamentals of the material's strength and the structural mechanics, describe the behaviour of a rigid body under the action of external and internal forces, describe the behaviour of elastic structures from the point of view of the analysis of the state of stress and deformation, analyse and solve structural analysis problems.

TEACHING METHODS

The subject takes place through theoretical lessons and applicative exercises, during which significant structural examples taken from built architecture are also recalled.

SYLLABUS/CONTENT

1) Rigid body equilibrium.

Actions (internal and external forces) and reactions (constraints and constraint reactions); principle of action and reaction; concentrated and distributed forces, volume forces. Statics and kinematics of the rigid body. The cardinal equations of statics. Calculation of constraint reactions.

2) Statics and kinematics of the beam.

Balance and congruence. Forces and displacements: stress characteristics and kinematics of displacements. Labile, isostatic, and hyperstatic systems. The indefinite equilibrium equations for the beam. State diagrams: normal force, shear stress, and bending moment.

3) Compendium of mass geometry and surface geometry.

4) Flexible and elastic curves.

Study of the rectilinear elastic beam: description of the state of deformation of the axis line (linear expansion and flexural curvature), deduction of the kinematic compatibility and constitutive relations, and formulation of the corresponding elastic problem, determination of the state of normal tension on the transversal section of the beam and execution of the strength verification.

EXAMS

EXAM DESCRIPTION

The exam consists of a written test whose contents concern the topics covered during the series of lessons.

ASSESSMENT METHODS

The learning assessment focuses on the contents exposed in class and consists of a written test.

The written test allows you to verify the acquisition of knowledge relating to the analysis of balance, strength, and deformability through the resolution of application examples that simulate real structural problems.
